Abstract

As the spatial, historical, and cultural nucleus of Carthage, the Byrsa Hill is a stark illustration of the erasure inherent in the city’s colonial reconstructions. In 146 BC, Romans obliterated the last resisting Punic forces in the acropolis on the hill’s summit, completing the genocide that was the third Punic War. A century later, Roman colonists radically reshaped the hill into the organizational nexus of a new colony, removing and burying Punic remains to form an enormous monumental platform . Although this platform was occupied throughout Carthage’s Roman, Byzantine, and Islamic periods, following its “discovery” by European explorers in the early 1800s, it became the center of French colonial excavations in the ancient city. In the last 160 years, the hill has been excavated by many different project directors, and the published archaeological datasets for the site vary widely in accessibility, quality, and completeness.
In this thesis, I use the Byrsa Hill as a case study to investigate systemic problems in the ways that archaeologists traditionally organize and publish their data. By integrating previously published architectural datasets from the Byrsa Hill, I uncover many inconsistencies and gaps, including vague, contradictory, and missing descriptions of Roman features from older and newer excavations. My restructured dataset enables new interpretations of the development of the site in the Roman period, in particular revealing the diversity of construction strategies employed during the complex’s Augustan-era construction. This interpretation contrasts with previous studies, which have uncritically and selectively used the problematic datasets to emphasize the unity of the complex’s design and construction. This lack of prior critical engagement, I will argue, shows that research on the site has been limited by divisions of labor and publication norms that remain common in archaeological research today.

Lay Summary

In this thesis, I investigate the Byrsa Hill, a site in the ancient Mediterranean city of Carthage (located in modern-day Tunisia). This site was the center of the ancient city for thousands of years, and, perhaps consequently, it has been a target for erasure by colonizers. Such erasure has been closely associated with the work of reconstruction, both during the foundation of the Roman colony 2000 years ago, and during the French occupation of Tunisia (1881-1956).
By digitizing previously published maps and profile drawings for the Byrsa Hill, I draw new conclusions about the site’s early Roman occupation, and I uncover many errors that have not been pointed out or corrected since the maps and profiles were published. The errors themselves, and the lack of prior corrections, point to deep and systemic problems in the ways that archaeologists of this site (and in general) traditionally manage and publish their data.

Preface

This thesis is my own original, unpublished, and independent work. All maps, diagrams, and other figures were made by me, unless otherwise specified.
All figures which were sourced from previous publications have been reproduced with permission from their respective publishers. Permission for figures from the volumes Byrsa I, Byrsa II, and Byrsa III was granted by École Française de Rome. Permission for figures from Deneauve (1983) was granted by Cahiers des Études Anciennes. Permission for figures from Deneauve (1990) was granted by l'Comité des Travaux Historiques et Scientifiques. In the chapters and appendices below, all of these figures are identified either by a conventional in-text citation (e.g., Deneauve 1983, 105 fig. 8), or a Figure ID (e.g., ). For an explanation of the Figure ID system, see Chapter 2, Section 2.1.
In-text citations and the bibliography of this thesis follow a modified Harvard format. In the interest of clarity, in-text citations referencing Byrsa I, II, and III use the short title of the volumes, rather than the author and year. Thus, a citation that would normally read (Lancel et al. 1979, 103) instead reads (Byrsa I, 103). This is to ensure that readers who are familiar with the site and accustomed to the title-based citation systems common in Francophone archaeological publications can easily identify these volumes.
A brief note is warranted on the internal-linking functionality embedded in the digital version of this thesis. In the PDF file, all cross-references are internal hyperlinks—i.e., clicking on them will take you to the locations they reference. Cross-references include references to chapters, sections, subsections, footnotes, as well as most in-text citations.

Acknowledgments

In scale, complexity, and pacing, this thesis has been by far the most difficult project I have ever done. It is the culmination of five years of working, learning and dreaming, and yet the vast majority of the project was compressed into the last five months and conducted mostly in solitude. After losing two vibrant communities and many, many friends to the COVID-19 pandemic, I spent thousands of hours alone in my bedroom, cataloging and correcting errors in other people's data, and trying to understand why so many generations of archaeologists have suffered under such similar circumstances and struggled with such similar problems. Words cannot express how prohibitively solitary the experience has been.
And yet, this thesis would not—could not—exist without the support of many other people. If not for the love, wisdom, and generosity of my family, my partner, my friends, and my colleagues, I would not be writing these words today.
Thanks first must go to my family, my partner, and my closest friends: Chris, David, Rebekah, Gus, Amber, Leif, Walker, Jaye, and Ben. These people loved me, encouraged me, and held me through some of the hardest days of my life.
Thanks also goes to my faculty advisors and mentors. My advisor, Prof. Kevin Fisher, and my second reader, Prof. Matt McCarty, provided insightful guidance and patient support throughout every stage of this project. They believed in me, my ideas, and my abilities, even when my project felt terribly overwhelming. Without them, I could not have brought this thesis to fruition. Prof. Fisher also provided partial financial support, in the form of money from the following grants: SSHRC #895-2018-1015 and SSHRC #435-2018-0463. Prof. Florence Yoon provided advice and support during the early stages of this project, and (perhaps unintentionally) she inspired my strategy to address one of its earliest challenges: the sustainable translation of large, highly-structured documents. Prof. Alison Wylie provided late-stage consultation on some of the systemic issues that I uncovered.
Thanks also are due to my friends from Green College, including Azhar, Sophie, Alison, Noga, Yotam, Hannah-Ruth, Saori, Sadia, Alicia, Steve, Aisha, Elahe, Alex, and many, many others. Much of the sentiment and conviction underlying this thesis were born in conversations with these friends, and their continual curiosity and kindness have been a source of great comfort and inspiration.
No less thanks are due to my friends from the CNERS department, especially Brianne, Lara, Anna, Gillian, Liz, Safia, and Ben (a different one). No one—not faculty, family, or (non-grad student) friends—will ever be able to understand what we went through this past year. Their openness, supportiveness, and utter grit comforted me, grounded me, and gave me the strength to keep pushing my project forward, even when it seemed that it would never end. A very special shoutout goes to Brianne, Lara, and Liz, who kept me sane during many long workdays in the Reading Room.
There are so many others I could thank here. My very good friends Danny, Wed, Anthony, and Jacob also listened to me and supported me and never failed to bring a smile to my face. UBC's librarians were invaluable—Evan Thornberry, Paul Lesack, Stephanie Savage, and Steve Bunnell, all of them provided very helpful consulting on this project. Help also came from staff at various publishers. Richard Figuier (from École Française de Rome), Pascale Fleury (from Cahiers des Études Anciennes), Patricia Millier (from Persée), and Agnès MacGillivray (Comité des Travaux Historiques et Scientifiques) all helped me to obtain the permissions I needed to reproduce many of the maps and profiles in my initial dataset, and their generosity is deeply appreciated.
I could go on for pages more, but I will end my list here. To all those whom I've neglected to name, thank you so very much. Your contribution to this project is not forgotten.

Chapter 1 Introduction: Reforming the Lifecycle of Archaeological Data

“Thus, we find ourselves in the contradictory position of being encouraged to pursue steady fieldwork, reminded in publications on the ethics of the profession that it is our obligation to publish our work promptly [...], yet the system of rewards and constraints under which academics labor pushes us against fulfilling standard publication requirements.” (Pollock 2010, 201)
This project started out as an inquiry into the role that the Roman reconstruction of the Byrsa Hill played in Augustus’ consolidation of power and legitimacy during the early years of his reign. The foundation of the Colonia Iulia Karthago was a massive logistical undertaking, involving the clearing, sorting, and reworking of vast quantities of stone rubble, and the excavation and transportation of hundreds of thousands of cubic meters of earth. The Byrsa was at the center of this tremendous labor: its summit, which had housed the Punic city’s acropolis, was graded down to virgin soil, and the sides of the hill were buried in a layer of backfill 2 to 3 stories high, creating a rectangular platform that covered an area of at least 35,000 m2, which is 3 times the area of the forum of Augustus at Rome (Gros 1992, 101).
1
This rough estimate does not include the area west of the cardo maximus, which was essentially unexcavated prior to Ladjimi-Sebaï's small investigation in 1994 and whose relationship to the rest of the complex is uncertain (see Byrsa I, 47, 55 and Ladjimi-Sebaï 2005, 94-97). The construction of a modern road after 1994 has likely rendered the area unsuitable for further investigation (Ladjimi-Sebaï 2005, 97).
This monumental complex served as the organizational nexus for the new colony’s uncompromising orthogonal grid, establishing the axes of the cardo maximus and decumanus maximus and constraining the dimensions of the insulae. In my original proposal, I laid out a plan for using the Roman Byrsa complex as a proxy to study the social and political ramifications of the foundation of the Colonia Iulia in the context of the early Roman empire.
The COVID-19 pandemic created many barriers to this research. Some barriers were expected: the Canadian government essentially banned travel to Tunisia, which precluded any form of ground-truthing, and to Italy and France, which precluded in-person archival research. There does not seem to be a centralized archive for the archaeological excavations on the Byrsa, not even for the UNESCO-backed excavations of the 1970s and 80s, and no smaller archive has been digitized or published online.
2
According to Mr. Turquin (pers. comm.), archives manager of l’Ecole française de Rome (“EFR”, publisher of the Byrsa volumes), the unpublished materials from the excavations (maps, drawings, etc.) are not housed in the EFR archives. Some of the personal materials of Serge Lancel may be housed in the Centre Camille Jullian, but they are not mentioned on the organization’s website.
Thus, I was limited to data which were published in books or articles—particularly the volumes Byrsa I, II, and III, which are the primary excavation reports from the 1970s and 80s, and which lacked the completeness and precision that may have been found in unpublished archives. Other barriers were unexpected: with the closure of libraries across the world, the Interlibrary Loan service stopped accepting requests for physical items, and it did not resume accepting requests until January of 2021—thus, for the first 3 months of this project I was limited to data which was published in books and articles that had been digitized and re-published online. This became a major cause for concern once I learned that Persée, the repository on which I depended for digital copies of Byrsa I and III (as well as many other articles), had digitized their sources using methods that created major distortions in maps, profiles, and other types of figures. It was only in January, when I was finally in possession of all of the physical books from the UNESCO-backed excavations, that I was able to diagnose the cause of the distortion problem and resolve it (see Appendix A).
Even as I resolved this pandemic-imposed problem, I began to encounter other roadblocks to data collection that were inherent in my sources, such as inconsistent data recording schemes, incomplete and selective site plans, and cursory or opaque analyses. I became increasingly preoccupied with the causes of those problems, many of which I have come to see as deeply rooted in the systems that have long structured—and still continue to structure—the lifecycle of archaeological data. These are systems of inquiry, by which excavations are conceived and planned to achieve specific priorities (i.e., to prioritize certain kinds of data); systems of excavation, by which data in the field are collected and organized, and by which the locations and final depths of excavation units are decided; systems of analysis, by which those data are turned into evidence for specific interpretations or claims; and systems of dissemination and storage, by which those data, evidence, interpretations, and claims are entangled together in figures (maps, profiles, photos, etc.), tables, and text, arranged in documents or other structured media (presentations, archives, databases, etc.) and made available to other scholars or the general public.
These problems are embedded in the practice of archaeological research today, particularly as it is conducted by western researchers working in the ancient Near East and North Africa.
3
By “western researchers,” I refer primarily to researchers from the United States, the UK, and France. Following Pollock (2010, 197-198), I do not mean to imply that archaeological practice is homogenous between (or even within) these countries. Rather, I wish to call attention to recurring elements in the various ways that archaeological research is practiced.
Problems of inquiry are evident, for example, in the neocolonial fixation on narrowly-conceived times and cultures—often “Roman” or “Greek,” or defined in opposition thereto—and the desire to selectively preserve their material remains as “cultural heritage,” to the intellectual neglect and physical destruction of others that are of more relevance and interest to local communities and stakeholders. Given the ubiquity of this problem, it is impossible to discuss representative examples in detail within the constraints of this thesis, but it has been identified in recent and on-going archaeological projects in Afghanistan, Egypt, Iraq, Tunisia, and many other countries.
4
General discussions of this complex problem can be found in Pollock (2010) and Meskell (2018). As Pollock (2010, 198-210) notes, this problem continues to be built into the frameworks of funding, publication, and employment that structure archaeological labor. This problem is too complex and widespread for a bibliography to be shared for each of the named countries, but a few illustrative examples may still prove helpful. For commentary on the problem in response to the destruction of the Bamiyan Buddhas in central Afghanistan, see Bernbeck (2010). For a discussion of the problem in excavations near the Egyptian village of Gurna (West Bank), see Meskell (2020). Isakhan and Meskell (2019) touch on the problem in their critique of UNESCO’s ‘Revive the Spirit of Mosul’ project, though their focus is on cultural heritage preservation and policy, rather than archaeological investigation. Some projects which have notably avoided this problem include Ronayne’s (2006; 2016) study of (and participation in) the campaign against Turkey’s Ilısu Dam and Forensic Architecture’s (2018) investigation into ISIL’s destruction of Yazidi temples.
In excavations on the Byrsa, these problems of inquiry first manifested in the early excavators’ obsession with the site’s Punic remains. In their quest to uncover Punic features, especially tombs, these excavators tore through the hillside, giving only cursory attention to Roman levels and essentially ignoring medieval Islamic remains.
5
Lancel (in Byrsa I, 13) puts it plainly: "Il faut le dire tout de suite : à Byrsa comme ailleurs à Carthage, le premier objectif des explorateurs des ruines de la cité antique fut d'abord, sinon exclusivement, la découverte des restes de l’époque punique.”
The later excavators of the 1970s and 80s attempted to rectify these shortcomings: they recorded Islamic remains when they found them (though these were relatively few and far between),

See e.g., the medieval cistern in reference grid cells , 12 and , 9 (shown on maps , , , , in profiles , and , and in discussion in Byrsa II, 190). For an explanation of the notation for reference grid cells, see n. 1. For an explanation of the notation used to identify maps and profiles, see Section 2.1.
and they carefully documented the Roman backfill and occupation layers in the few locations where their stratigraphy was undisturbed.
7
See e.g., discussion on the “Butte of Lapeyre” in Byrsa I, 97-142
Ironically, these lacunae in Roman and medieval remains at times forced them to focus most of their attention on Punic features and artifacts, unavoidably reprising the proclivities of their forebears. This association was strengthened by the tone of their mission, which was situated within UNESCO’s larger campaign to “Save Carthage” from encroaching urban development.
8
On the inception and development of the UNESCO campaign at Carthage, see Ladjimi-Sebaï (2005, 45 n. 158) and references therein. UNESCO’s efforts to uncritically preserve “cultural heritage” according to narrowly western definitions are well documented (Meskell 2018). The violence and alienation caused by this work, and the role of archaeologists as perpetrators, has only recently begun to be examined (e.g., Bernbeck 2010; Pollock 2010; Bernbeck and Pollock 2016; Pollock 2016; Meskell 2020).
On the Byrsa, that meant mostly saving ruins from the Punic city, since prior excavations had greatly diminished or outright destroyed the Roman, Byzantine, and Islamic remains.
9
Prior excavations are not only to blame—so too is the construction of the Saint-Louis Chapel (founded 1840), Cathedral (founded in the late 1880s), and Museum. As Ladjimi-Sebaï (2005, 57 n. 207) points out, the museum first coalesced around the materials uncovered during the Chapel's construction.
Problems of excavation involve deficiencies inherent in the techniques and decisions that directly govern the collection and recording of data. In the UNESCO-backed excavations on the Byrsa, these issues are evident, e.g., in the lack of proper stratigraphic illustrations in certain sectors (Section 6.1), the lack of comparative data on the construction of the foundation piles (Section 5.1.2), and the lack of technical description of the only extant remains of the Augustan apses (Section 5.1.3). As I will explore in Sections 6.3 and 7.1, these problems are linked to traditional divisions of labor and publication norms in archaeological research. In other words, these are systemic problems, not personal ones.
Problems of analysis involve the opaque creation of “archaeological fact”, in which the distinctions between “data” and “interpretation” become blurry or disappear entirely. For example, as I discuss in Chapters 5 and 7, it is sometimes very difficult (if not impossible), in the maps of Byrsa I, II, and III to see which features were found in situ and which were speculative or reconstructed. This sort of ambiguity makes it very challenging to independently evaluate the excavators’ analyses and reuse their topographical data.
Because problems of excavation and analysis can only be identified through the careful review and analysis of excavation records, they can become obscured by problems of dissemination and storage, which are more intractable and farther reaching. On the Byrsa Hill, the problem can be put simply: the results of excavations can be accessed only by a few dozen scattered articles and several books.
10
Traditionally, western archaeologists tend to distinguish books between “monographs” (one topic, generally one author) and “edited volumes” (multiple topics, multiple authors). Historically, excavation results have tended to be published under a single author (typically the site director), but multiple-author volumes did sometimes occur. Archaeological research on the Byrsa has been published in both—Byrsa I and II can be considered edited volumes, and Byrsa III a monograph.
These sources, even those from the UNESCO-backed excavations, contain major gaps, and yet there are no centralized archives for the unpublished excavation records.
11
For a discussion of the gaps in technical description of the Roman foundation piles, see Section 5.1.2. For a discussion of ambiguities and inconsistencies in the figures of Byrsa I, Byrsa II, and Byrsa III, see Section 6.1 and Appendix D. Gaps in sources prior to the UNESCO-backed investigations are discussed throughout. On the lack of centralized archives for excavations on the Byrsa, see n. 2.
This problem is situated within a broader “publication crisis” in archaeology, which has remained entrenched despite numerous attempts to address it over the last 50 years. This crisis is complicated by the fact that book publication continues to be a crucial (and increasingly difficult) barrier to professional entry into academic archaeology.
The published results of the UNESCO-backed excavations are essentially limited to Byrsa I, Byrsa II, and Byrsa III.
12
Some additional results are published in Gros and Deneauve (1980) and Deneauve (1983).
Each of these volumes was published no more than 5 years after the last of its data was collected: Byrsa I (published 1979) covers excavations in 1974–1976, Byrsa II (published 1982) covers excavations in 1977–1978, Byrsa III (published 1985) covers excavations in 1977–1980. Within the literature on Carthage more broadly, this timeframe is unusual, as most publications were delayed by 10 years or more. The volumes for the British excavations (1974–1979) were delayed by 5 years (1984) and 15 years (1994).
13
Some additional work was conducted in very limited fashion in 1980, 1982, and 1983 (Hurst 1994, xi). Hurst himself (1994, xi) acknowledges that this delay lasted a “long time.”
The volumes for the German excavations (1974–1980) were delayed by 11 years (1991) and 17 years (1997). The volumes for the Swedish excavations (1979–1983) were delayed by 19 years (2002 ) and 35 years (2018). These large publication delays can be found at many other sites across the Mediterranean,
14
Two examples from the eastern Mediterranean bear mentioning. The first example is the royal palace of Ugarit, a massive complex dating to the Late Bronze Age. Although the palace was excavated in the 1950s under the direction of Claude Schaeffer, systematic study of its architecture only began in 1989. This new project, which is under the direction of Jean-Claude Margueron and Olivier Callot, is still ongoing (Matoïan 2008, 20). To date, the project has only produced several preliminary publications (Callot 1986; Margueron 1995). The reason for the absence of further publications is unclear—Schaeffer’s documentation may have become misplaced or withheld (as Matoïan (2008, 30, 48) seems to imply), and after 2011 is it possible that the Syrian Civil War stymied field and archival research. A second example is the Uluburun shipwreck off the southeast coast of Turkey. Considered the best-preserved instance of a LBA shipwreck, the site has been the subject of over 40 years of excavation and research. Despite this attention, there has been no comprehensive publication of the site, even though it has produced numerous papers and theses—c.f. the overviews published by site director Cemal Pulak (e.g., 1998) and Shih-Han Samuel Lin’s (2003) remarkably exhaustive M.A. thesis, which was written under Pulak’s supervision.
and they reflect the fact that it is enormously difficult and expensive to prepare excavation records for publication as a book.
The protracted delays in preparing such books are not helped by the fact that they are often unsatisfactory, either because they are impersonal (Hodder 1989), or “boring” (Boivin 1997 quoted in Opitz 2018), or incomplete (as I explore in the chapters below). Implicit in these problems is a sort of tension between the need to acknowledge the narrativity inherent in archaeological observations and analyses, and the need to transparently document those observations and the logic of those analyses for other scholars and the general public. The idea that a book-centric approach to site publication is inadequate for addressing this tension has been debated since the early 20th century (Richards 2004), but it first received widespread consideration (at least among British scholars) in the late 1970s with the publication of the Frere report (Frere 1975). Since then, it has occasionally been examined by committees (see especially Cunliffe 1983 and Carver et al. 1992) and written up in personal observations (e.g., Pollock 2010; Morgan 2013).
15
As far as I can tell, the only books published on this subject are Shanks (1996a) and Shanks and Magness (1999), both of which (rather ironically) have gone out of print.
Prior to the 2000s, these efforts were largely ineffective, because the technologies necessary for quickly connecting distant researchers with excavation archives were either inaccessible or did not exist (Richards 2004). As the internet has matured and digital publication tools have proliferated, some excavations have adopted hybrid research schemes that attempt to balance open or accessible archiving with more conventional publication media (e.g., Opitz, Mogetta, and Terrenato 2016), but these are still exceedingly rare. In general, for a variety of reasons, traditional books remain the standard for site publication.
16
The reasons for this are complex and differ between countries. As Morgan (2013, 282-283) points out, the permit requirements of host countries (among other legal factors) often dictate the pace at which preliminary (i.e., “interim,” but all too often final) reports are published, and differences in research cultures can place varying amounts of emphasis on primary data vs. interpretation.
Previous treatments of this issue have largely viewed it through theoretical and methodological (and sometimes economic) lenses: what is the nature of archaeological data and interpretation, and how should they be disseminated to be more accessible and useful (and more cost-effective for taxpayers)? Somewhat less discussed is the problem’s professional dimension.
17
Though see Pollock (2010, 202-203) and Morgan (2013, 284).
As academic Review, Promotion, and Tenure (RPT) requirements have steadily increased at north American institutions over the last 20-30 years (Schimanski and Alperin 2018; Alperin et al. 2021), book publication has continued to be the “gold standard” of applications for tenure within the humanities (Estabrook and Warner 2003).
18
Estabrook and Warner’s (2003) study constitutes, as far as I can tell, the only interview and survey-based statistical evaluation of the role of book publication in RPT requirements. Cronin and La Barre’s (2004) study has a similar purpose but is based on an analysis of official written criteria, rather than personal surveys and interviews. While Estabrook and Warner’s (2003) study is now a bit dated, their results are still readily accepted in broader studies of RPT requirements in higher education (e.g., Schimanski and Alperin 2018; Alperin et al. 2021). Estabrook and Warner (2003) interviewed researchers exclusively in History, English, and Anthropology departments, but their findings seem applicable to the field of Classics as well.
This is in spite of the fact that a majority of academics do not believe book publication should be a requirement, nor that a book is necessary to present their scholarship; moreover, failure to complete a monograph correlates overwhelmingly with departure without tenure (Estabrook and Warner 2003).
19
Only among historians did Estabrook and Warner (2003) find a majority of respondents (65.6%) who favored the book requirement. Interestingly, they found no relationship between respondents’ age or tenure status and their opinion about the book requirement. Out of the respondents who left their institution without tenure, 74% (23 out of 31 respondents) had started but not completed their book (these data are viewable in tabular form in an online supplementary page, retrievable from https://web.archive.org/web/20040113221620/http://lrcsurvey.lis.uiuc.edu/surveys/99EZJ2/99EZJ2_0001.html).
I believe this problem can be tied to a lack of training and institutional support in archaeological data management. Archaeologists deal with an incredibly diverse array of data types from a myriad of sources and contexts, and they have the singular responsibility, to an extent perhaps unique among the sciences, to serve simultaneously as excavator, curator, archivist, and writer—to which may be added programmer or webmaster, if they intend to digitally publish their excavation archives. These roles are simultaneous, not sequential. The plans of the writer depend on the plans of the excavator, curator and archivist: the publication of a site report that is integrated with a digitally accessible excavation archive (e.g., Opitz, Mogetta, and Terrenato (2016), whose project design is discussed in Opitz 2018) is logistically impossible if the excavation plans, data recording plans, and data organizational frameworks are not constructed with it in mind. This means that even before the archaeologist sets foot onsite, she needs to have decided how she will meet the needs of scholars who will read her report and reuse her data.
20
Opitz (2018) and Morgan (2013) also argue for the importance of a reader-centric framework. The needs of those who re-use archaeological data are explored from a data science perspective in Faniel et al. (2013).
These requirements make it clear that archaeologists are, in a very real sense, data scientists. Yet while we are taught how to collect, critique, and analyze data, we are not formally trained to organize, structure, or store it.
In this way, the aim of my project has become two-fold: to use the site of the Byrsa Hill as a case study for systemic problems in archaeological data management, in order (I hope) to improve the state of the publication of the site, opening it to wider inquiry. After digitizing and collating most of the previously published cartographic data, I will integrate the data into a single georeferenced dataset. From this initial dataset, I will extract the georeferenced extents of the most important Roman and Punic architectural features, and I will synthesize the existing data on each of them. This combination of extraction and synthesis will produce a new, restructured dataset of most of the Roman and some of the Punic features, which will allow me to pose new interpretations and ask new questions of the site. The entire restructured dataset will be openly published online, enabling readers to replicate my maps and measurements.
21
My initial and restructured datasets are included in the supplementary files accompanying this thesis. My restructured dataset is also published in two repositories: https://github.com/josephburkhart/Byrsa-Archive-Static and https://github.com/josephburkhart/Byrsa-Archive-Active. The first repository mirrors the supplementary files—that is, it will not be altered or corrected in any way. The second repositoty contains an actively updated version of the restructured dataset, to which new features, corrections, and additional information will be added after publication.
A last note. The colonialism inherent in my project should be acknowledged plainly. Firstly, I am a white, settler-colonial, cis-het-identifying man, living and working in Vancouver, British Columbia, on land that was taken by force from the hənqəminəm-speaking xʷməθkʷəyəm (Musqueam) people, who have lived here for many thousands of years, and whose heritage, knowledge, and ways of being are still actively being destroyed today. I directly benefit from the oppression of these people, even though I have tried hard to learn about their history and culture, and to work against the systems which oppress them. Secondly, much of the data I use in my project was collected within colonialist and/or racist systems of thought, which saw Greeks and Romans as beacons of civilization enlightening dark and savage peoples through colonization and assimilation, and which positioned the European colonizers of the 18th, 19th, and 20th centuries as their direct descendants and rightful successors in this quest. These schools of thought had diminished by the time of the UNESCO-backed investigations of the 1970s and 80s, but aspects of them still persisted, and continue to persist today. Thirdly, I am using these data primarily to investigate the social and political implications of imperial Roman colonization. The deaths of Carthage, first in the genocide of 146 BC, and second in the razing and reconstruction of the imperial colony, constitute one of the most profound acts of colonial erasure in all of Roman history. As the observant reader may note in the sections below, the past 160 years of excavation on the Byrsa Hill have in some ways reprised that second death, largely erasing thousands of years of material history through destructive excavation and incomplete publication. It is my earnest hope that this project may set at least a small amount of that injustice to rights.

“A plan of the excavations (Pl. XI) will be found attached to this notice. It was executed by M. Bonnet-Labranche, a diocesan architect. The letters and numbers inserted in the text refer to the said plan.” (Delattre 1893a, 95)
“Nous donnons une description sommaire des divers vestiges conservés ou reconnus, en les répartissant par paliers que nous désignerons par le chiffre de leur altitude”
“We give a summary description of the various remains preserved or recognized, by dividing them in stages which we will designate by the number of their altitude” (Saumagne 1924b, 178).
The three quotes above illustrate some of the different approaches that previous researchers have taken to identifying figures, features, and feature locations on the Byrsa Hill. Since excavations began in the 1850s, the site has seen more than a dozen project directors, and about as many notation systems. Generally, each new system has been presented as a matter of course, with little to no rationale for its design or explanation of its function. As I will show in Chapter 5, more care is needed when attempting to work with data on the scale of an entire site. In the sections below, I will explain the systems that I use to specify figures, features, and feature locations.

Figure ID System

The past centuries of excavation on the Byrsa Hill have produced a truly dizzying quantity of maps, sections, and other geospatial illustrations. The fraction of these that saw the light of publication are scattered across many dozens of articles, bulletins, and books, although the majority of them can be found in the Byrsa volumes. In order to create an integrated dataset of the Roman and Punic structures on the Byrsa, I must draw upon well over a hundred of these graphics, considering their ambiguities and inconsistencies, determining their original geospatial extents, and clearly linking them to the data and feature traces that I derive from them. Due to publishing restrictions, I cannot reproduce all of these figures in my thesis; for most of them I can only provide a citation. It is critical that these citations be meticulous, since my results cannot be reproducible if my dataset is not clear.
Proper citation is made more difficult by the fact I must identify not just the publication and the location of the figure within it, but also the person or entity who digitized that publication. As I discussed in Chapter 1, for most of this work I have been limited not just to drawings that have been published, but to drawings that have been digitized and re-published online. During digitization, figures can become distorted by random or systematic errors, to the point where they become unusable—this problem is abundantly clear, e.g., in Persée's digitized editions of Gros and Deneauve (1980) and Byrsa I and III (see Appendix A). While I have done my best to rid all of my data of such errors, identifying the person or entity who performed the digitization is still necessary to ensure that other scholars can potentially identify errors that I have missed, so that they do not propagate to other studies that draw from my results.
As a result of these requirements, it is difficult to include enough citation information for every figure while maintaining overall readability. To obtain a balance, I will employ a figure ID system that clearly identifies a figure's original publication, location within that publication, and the publication's digitizing entity, all within a unique, compact code. Each code is composed of three identifiers separated by a full stop:

Feature ID System

There are thousands of Punic and Roman features in prior publications on the Byrsa Hill. Many of them are never identified unambiguously, and many are shown on maps with ambiguous symbology that makes it difficult to distinguish features that were actually found from features that were merely reconstructed or hypothesized by the excavators.
I have attempted to resolve these problems in two ways: first, by limiting myself to digitizing only large structural features (walls, cisterns, etc) and mostly omitting architectural fragments; second, by creating a new organizational framework in which each feature is given a unique alphanumeric ID that encodes its ontological category. I am acutely aware that the creation of a new identification system for a site with decades of data may prove naïve, if not futile, so in designing this system I have sought to prioritize accessibility to francophone scholars and compatibility with previous IDs. Each ID is composed of a type code, subtype code (optional), number, and ontological code:
These codes and numbers are combined in the format [type]-[subtype][####][Ontology], so that, for example, refers to an extant apse semicircular wall (or piece of a wall), and refers to a reconstructed cistern (or piece of a cistern).
All of these feature IDs are presented in tabular form with corresponding maps in Appendix C. In these tables, I identify the map from which the feature was traced, and any underlying assumptions that were necessary to complete the trace.
In the interest of full transparency, I have also created unique IDs for the axes I used in my reconstructions. When the reconstruction of a feature involves the use of one of these

axes, I reference the ID for that axis in the feature trace table in Appendix C. A table and accompanying map of these axes is also included in Appendix C.

Feature Location System

The excavators of the French Mission created a customized grid system to allow themselves to specify feature locations in an imprecise but concise fashion. This system divides the entire site into 2020 m major grid cells ( through ) that are identified by column (A through Q) and row (I through XX). The major grid cells are then subdivided into a 44 grid of 55 m minor grid cells (1 through 16). A feature's location is then specified by combining the ID of a major grid cell with the number of one of the interior minor grid cells (e.g., ).
23
There is very little discussion of this system in the Byrsa volumes. Cursory descriptions are provided by Lancel (in Byrsa I, 59) and Gros (in Byrsa III, 5 n. 1). Illustrations of the major grid cell identification system can be found in and , 010a, and 010b. Illsutrations of the minor grid cell identification system can be found in , 010a, and 010b.
This system is the key to georeferencing most of the maps and profiles in the Byrsa volumes. Unfortunately, much of the system was not published, and I had to reconstruct it from the pieces that were. My reconstruction of the grid system will be presented in Chapter 4.
This feature location system works well for concisely (albeit imprecisely) locating figures on a sitemap, and I have chosen to use it in this thesis in order to ensure compatibility and comparability with previous scholarship. It must be noted that a drawback of this system is its opacity to readers who are not already familiar with the site. For example, designating a wall's location as “” would mean nothing to a reader who did not already know that major grid cell is in the southwest corner of the complex. To compromise between these competing demands for compatibility and accessibility, I have elected to use the system sparingly in my discussion of various features, but to embed it deeply in the feature metadata that is presented in Appendix C and included in my supplementary files,

Chapter 3 An Abridged History of Excavations on the Byrsa

“C'est de cette idée de l’interdépendance, non seulement technique, mais monumentale, de l'ensemble des vestiges qu’il convient de partir pour reprendre l'étude de cette colline dont le malheur paradoxal est d’avoir été trop explorée.”
“It is from this idea of the not only technical, but also monumental interdependence of all the remains that we should start to resume the study of this hill, whose paradoxical fate is to have been explored too much.” (Gros in Byrsa III, 25)
The history of excavations on the Byrsa Hill spans 160 years and more than a dozen different project directors. For the first century or so, basically all of the project directors operated independently, with almost no coordination. They ranged widely over the hillside, largely avoiding the areas excavated by their predecessors. Their open-air excavations removed huge quantities of earth and materials, as they searched for features of interest (primarily Punic tombs and inscriptions). When they documented other features at all, they described them briefly and vaguely. Those features very rarely survived the destructive combination of natural erosion and spoliation that followed from excavation, so their descriptions, however cursory they may be, often remain indispensable. Consequently, any large-scale investigation of the Byrsa Hill must give an account of the site’s excavation history.
That history is too long and convoluted for a full account to be included here, but a very abridged account should still prove helpful.
24
For longer, more detailed accounts of this history, see e.g., Lancel (in Byrsa I, 13-55), Ladjimi-Sebaï (2005, 39-101), and most recently Ennabli (2020, 72-109).
For the sake of clarity and brevity, I will not discuss every researcher in this chapter, only those whose findings are pertinent to my datasets. I will also not discuss those findings in detail; such details will be provided, when necessary, in Chapter 5.

Charles-Ernest Beulé (1859)

While the Byrsa Hill was included in a number of loose surveys in the 1700s and early 1800s (e.g., Shaw 1738; Humbert 1821; de Chateaubriand 1859),
25
For the reference information on Humbert (1821) see Audollent (1901, xxiii, 822).
Beulé was the first western researcher to excavate on the site. A French archaeologist and politician with a thorough education in classical literature and history, Beulé had first made a name for himself by excavating on the Athenian Acropolis, where he used a large amount of explosives to uncover a Roman staircase and a Byzantine postern gate (Campbell 2007). During his single, self-funded excavation season (1859), Beulé made a massive informal ground survey of the hill and its immediate surroundings, and his team of excavators (mostly local workers) conducted at least 11 different excavations. Beulé published a very inaccurate map of the survey and excavations, along with a description of their results in Fouilles À Carthage (1861), a rather rather rambling and confused, albeit enthusiastic book, replete with quotes from and references to ancient authors.
26
For the map, see Beulé (1861, pl. I).
The excavations that will be relevant for my dataset are “Fouilles G” (1861, 46-65), which uncovered some apses along the south side of the Roman Byrsa complex; “Fouilles F” (1861, 42), which provided an approximate height for the Roman complex in its southeast corner; “Fouilles K” (1861, 39), which revealed remains of what would later be recognized as a wall of interlocking amphorae, but which the researcher mistook for a cellar; and “Fouilles I” (1861, 66-74), which uncovered another alignment of apses along the complex’s east side.

Alfred-Louis Delattre (1880-1897)
27
Dates of excavation are from Ladjimi-Sebaï (2005, 41).

Almost thirty years after Beulé’s expedition, Delattre began conducting excavations in many locations on and around the hill. These excavations were conducted under the authority of the Pères Blancs, an ecclesiastical order that was tied first to the Saint-Louis Chapel and later also to the Cathedral, and of which Delattre was a member.
28
For further discussion of the Pères Blancs and their role in the early excavation history of Carthage, see Altekamp and Khechen (2013, 472-477) and references therein.
Delattre had a penchant for bite-sized publication, resulting in a mess of small articles and reports that are often vague, repetitive, and confusing.
29
For a list of these publications, see Freed (2001). Ladjimi-Sebaï (2005, 41 n. 139) notes that the mess has been greatly clarified by Benichou-Safar (1976).
For my datasets, his most important excavations are those in the complex’s southwest corner, where he uncovered part of the substructural walls of a temple (Delattre 1893a; note that the excavator mistook these foundations for the walls of a bastion); the south perimeter, where he uncovered an alignment of apses that originally were continuous with those found in Beulé’s “Fouilles G” (Delattre 1893a); and the southeast perimeter, where he found more apses that were backed by a wall of interlocking amphorae (Delattre 1893b; Delattre 1894).

Charles Saumagne (1923-1926)
30
Dates of excavation are from Lancel (in Byrsa I, 35); cf. Ladjimi-Sebaï (2005, 41), who omits 1923.

In 1923, Saumagne began directing a new archaeological project focused on the east side of the complex under the auspices of the Direction des Antiquités et Arts de Tunisie (Saumagne 1924b, 177; Byrsa I, 35).
31
This organization seems to be identical to the Service des Antiquités et des Arts discussed e.g., in Altekamp and Khechen (2013, 473). While Saumagne (1924b, 177), Lancel (in Byrsa I, 35), and Ladjimi-Sebaï (2005, 42) refer to the organization as “la Direction”, Ladjimi-Sebaï (2005, 156, 158) also refers to it as “le Service.”
The excavations and surveys from this project produced the first map to cover the entire site (Saumagne 1924b, 181 plan II), which included very rough elevation measurements. Saumagne continued the project in 1925 and 1926, but he never published the results of these later campaigns (Byrsa I, 35 n. 65); they were finally taken up and brought to publication over 50 years later in Byrsa I. Saumagne (1924a) also investigated urban layout of Roman Carthage and its relationship with the surrounding rural cadastration, but these findings are less relevant for this thesis.

Gabriel Guillaume Lapeyre (1930-1938)
32
Dates of excavation are from Lancel (in Byrsa I, 25) and Ladjimi-Sebaï (2005, 43).

Four years after Saumagne’s investigations had concluded, Lapeyre, another member of the Pères Blancs, began a new project focused on the southern side of the complex. Over the next eight years, Lapeyre conducted a series of excavations that uncovered numerous Punic tombs and Roman substructures, one of which he enthusiastically mistook for part of a Punic enclosure (Lapeyre 1934).
33
This feature is identified as wall D in the Byrsa volumes—see Section 5.1.1.1. Lapeyre deliberately misrepresented this feature in his maps and descriptions—see n. 53.
The quantity and locations of these excavations are difficult to pin down, because their results were published very incompletely and imprecisely, when they were published at all (Byrsa I, 25). Lapeyre recorded almost no stratigraphic information, and his excavations destroyed the vast majority of the Roman strata for the south side of the complex.

Colette Picard (1947)

Intrigued by some features found by Lapeyre under a large building in the southern part of the complex,
34
This is the building “with a basilica plan” (Ladjimi-Sebaï 2005, 43; Byrsa I, 33; Lapeyre 1934, 338 n. 3). This building is a later construction and will not be included in my datasets.
Picard, who was then the curator of the site of Carthage, conducted a limited investigation of the area (Ladjimi-Sebaï 2005, 43; Byrsa I, 31-32). She determined them to be non-funerary walls dating to the late 3rd or early 2nd century BC, near the end of the Punic period (Picard 1951).

Jean Ferron and Maurice Pinard (1950-1958)
35
Dates of excavation are from Ladjimi-Sebaï (2005, 44); cf. Lancel (in Byrsa I, 33), who omits 1950-1951.

Several years after Picard’s investigation, Ferron (another member of the Pères Blancs) and Pinard (an architect) began directing a new project which resumed Picard’s excavations and extended them to the south (Ladjimi-Sebaï 2005, 44; Byrsa I, 33). Underneath the Roman embankment, they found the remains of some Punic buildings along an orientation that was different from the Roman layout. The results of these excavations, while rudimentary, were published rather promptly and completely (Ferron and Pinard 1955).
36
This publication notably includes an extensive finds inventory, which appears to contain mostly ceramics. Unfortunately, the inventory cannot be easily searched because the openly published digitized version of the publication is missing critical text-encoding metadata.
Afterwards, Ferron and Pinard extended their excavations eastwards, where they found remains of more Punic buildings grouped into city blocks. The results of these later excavations were published in similar fashion to the earlier ones (Ferron and Pinard 1960).

Serge Lancel et al. – The French Mission (1972-present)

By the early 1970s, decades of real estate prospecting and urban expansion had caused ancient Carthage to be almost completely subsumed under modern constructions.
37
For further discussion of this expansion, see Altekamp and Khechen (2013, 473-479) and references therein.
In 1972, at the request of the newly independent Tunisian government, UNESCO launched an international campaign to excavate remaining parts of the ancient city, to keep it from being completely destroyed.
38
For further discussion of this campaign, see Ladjimi-Sebaï (2005, 45 n. 158) and references therein.
The Byrsa Hill was re-entrusted to French institutions, and the Académie des Inscriptions et Belles-lettres created a new project, the Mission Archéologique de Carthage-Byrsa to lead the new excavations, with archaeologist Serge Lancel as the overall project director (Morel 2011b). This project, which I will hereafter call “the French Mission,”
39
It must be noted that there were previous missions françaises, which were associated with the Pères Blancs.
began excavating in 1974, and has continued to excavate more or less continuously ever since (Morel 2011b). The project was divided into several teams: the first team (responsible for “sector A”) was lead by Serge Lancel with the assistance of Jean-Paul Thuillier, the second team (responsible for “sector B”) was lead by Jean-Michel Carrié and Nicole Sanviti (succeeded in 1978 by Jean-Paul Morel), and the third team (responsible for the summit and parts of the southern slope) was lead by Pierre Gros with the assistance of Jean Deneauve, Marie-France Giacobbi and Françoise Villedieu (Morel 2011b). A handful of architects have contributes to the project, in particular Gérard Robine, as well as the technical artist Philippe de Carbonnières. Jean-Paul Morel became the director of the project in 1983, a position he still occupies today (Morel 2011b).
The primary publications to come out of this project are Byrsa I, II, and III. Primary excavation results can also be found in several other articles (e.g., Gros and Deneauve 1980; Deneauve 1983; Morel 2011a). While there have been several indications that Byrsa IV and V are in the works, there has been no other major long-form publications from the project since 1985, when Byrsa III was published.
40
Morel (2011b) notes that Byrsa IV is forthcoming, to be published by the École Française de Rome, as with the previous three volumes. Morel was awarded a White Levy grant in 2013 to support the publication of Byrsa V (https://whitelevy.fas.harvard.edu/people/jean-paul-morel), but I have found no other mention of it.

Chapter 4 Collating the Cartographic Data

To date, no large-scale map has been published that indicates features' dimensions, orientations, dating, and construction for the entire Byrsa Hill complex.
41
This lacuna is particularly frustrating because there already exists a physical model of the Roman Byrsa in the Antonine era, which was constructed in the mid-1990s—see Section 5.1.3.4, esp. n. 157.
Ideally, this map should also show elevation data for the upper and lower extents of the features, or at least show the extents of other figures in which elevation data are encoded (such as profile drawings—see Chapter 6). Instead, a multitude of smaller maps have been published (mostly in the Byrsa volumes), which are drawn in different styles, emphasize or omit different features, and conform to varying standards of accuracy and precision. In this Chapter, I will show how I have integrated these smaller maps into a single cartographic dataset, which I will call my “initial dataset.” In the next chapter, I will show how this integration revealed many ambiguities and inconsistencies in prior maps, and how I resolved or mitigated them to produce a final dataset that is as internally consistent as possible.
The first step to producing a unified sitemap is to “georeference” each map in the initial dataset—that is, to determine the extents that it represents within a Coordinate Reference System (CRS).
42
In the Byrsa volumes, the site spatial reference grid system was established on axes of the “Lambert Nord Tunisie” projection (Byrsa I, 33 and 59, n. 2; Byrsa III, 5, n. 1), which is used in the projected CRS “Carthage / Nord Tunisie” (EPSG:22391). Grid North (GN) for the site grid is therefore equivalent to GN for the projection (Byrsa II, 299), which, noteably, is not equivalent to Magnetic North—hence, bearings are generally recorded relative to GN to avoid confusion (e.g., Byrsa II, 376). This CRS is also used by the Swedish Excavations (Styrenius et al. 1986, 82).
Visually, this causes the maps' features to overlap, making it easy to compare features between multiple maps and create traces of their outlines. As far as I can tell, it is not possible to directly georeference any of these maps: none of them display their original datums (reference points within the CRS), and none of their parent publications provide other definitions of their extents, such as coordinates or gridlines in their CRS. Consequently, each of these maps must be georeferenced indirectly, with their contents visually aligned with the contents of other maps either in the initial dataset or some external dataset.

Basemap

The best candidates for basemap were and .
43
Another candidate is , which I did not find until I was near the end of this project. While offers better, more targeted coverage of the reference grid than and , it suffers from several key deficiencies, which are discussed in Section 5.1.1.
Both maps displayed large sections of the reference grid, covering most, if not all, of the Byrsa hill, and both maps also displayed two modern buildings (the Saint-Louis Cathedral and the Carthage Museum), enabling them to be georeferenced relative to features in modern maps. was chosen over for three reasons. First, covers a larger area (over 125,000 m2 more than ), so its reference grid should be more representative of both the hill and its surroundings.
44
is about 410 * 440 = 180 , 400 m2. is about 213 * 250 = 53 , 250 m2.
Second, is printed in a larger scale (1:1000, while is approximately 1:1500), so it should be more precise and less susceptible to printing-induced error.
45
The caption to says that the map is a “réduction au 1/1000e” of a 1:500 plan, but this scale must apply to the drawn map, rather than the printed one.
Third, is drawn in a more exact-looking style, with thinner lines and less stylized features, suggesting that it is intended to be less schematic than . One notable drawback to is that it displays significantly fewer major grid cells (81 compared to 's 120), but these are spread out over a larger area. As I will show in Section 4.2, the missing sections of the reference grid in can be reconstructed from the existing ones.
Before the reference grid could be reconstructed, the basemap had to be georeferenced relative to an external dataset, so that the derived grid would be georeferenced as well. Conventionally, digital georeferencing is carried out using algorithms that determine the “best fit” for a map, given some reference coordinates—the algorithm scales and warps the image, and translates it to its georeferenced location. It is important to give the algorithm as many reference coordinates as possible and to make sure that they are spread out over the whole map, otherwise the algorithm will determine the best fit only for part of the map. In , modern buildings were only shown in a small part of the map, near the summit, so georeferencing the map relative to these buildings would not produce a good fit for most of the site. Because would be used to derive the reference grid, it was essential that the grid cells on the georeferenced map have the correct dimensions. Consequently, was georeferenced twice. First, it was algorithmically georeferenced relative to an idealized 2020 m grid to ensure that the map's grid was properly scaled.
46
All georeferencing was performed using the “Georeferencer” tool in QGIS 3.16.0. The algorithm used for was “Linear.” For every other map, the algorithm used was “Polynomial 1.”
Then, it was manually translated and rotated so that the footprints of the modern buildings in the map overlapped with the corresponding footprints in an external dataset.
47
Rotation was performed using Guilhem Vellut's open-source Freehand Raster Georeferencer plugin (version 0.7.1).
The external dataset used for this purpose was from OpenStreetMap (OSM),
48
This data was published by OSM user ulrichm under the Open Data Commons Open Database License, meaning that it is free to use and re-publish with proper citation.The data is part of Ideally, the external dataset would have come from a local, municipal source; such datasets tend to have much higher resolution. Unfortunately, no such sources appear to be available online.
because its building footprint fit the 's building footprint most closely (data from Google Maps was also evaluated—see Figure 4.1).

Reconstructing the Reference Grid

As was mentioned in Section 4.1, the reference grid in is incomplete. Major grid cells have only been drawn in two areas of the map, leaving large swaths of the site uncovered. Moreover, the minor grid cells have not been plotted at all—in fact, this is the case for all large maps of the site. Both lacunae can be resolved from the existing data:Apses the missing major grid cells can be reconstructed by extending the lines of the existing grid, and the missing minor grid cells can be re-created by mathematically defining a 44 grid for each major grid cell.
The reconstruction of the major grid cells proceeded as follows. "Horizontals" and "verticals" are the lines of the grid, and are referenced by the cells that they run between and around (Figure 4.2). Consequently, "the horizontals from " denotes the 4 East-West lines that run between and around cells . When horizontals or verticals are referenced for more than one row or column, they are constructed from the outermost vertices of those cells (the inner vertices are ignored).

Figure 4.2: Horizontals (dotted lines) and verticals (solid lines) for major grid cells - , overlaid on .
The first cells to be reconstructed were those whose boundaries either were directly plotted on the basemap, or could be determined by extending existing horizontals and verticals (Figure 4.3). Cells and were traced directly from the basemap. Cells were drawn by intersecting the horizontals from with the verticals from .

At this point, two blocks of cells had been reconstructed, leaving a gap corresponding to cells (Figure 4.4). The boundaries of cells were determined by first drawing horizontals between the eastern vertices of and the western vertices of , and then intersecting those horizontals with verticals drawn along their quadrants. Cells were drawn by intersecting the horizontals of with the verticals from . Cells were drawn by intersecting the horizontals from with the verticals from .

To ensure that no part of the site fell outside the bounds of the reconstructed reference grid, two additional rows of major grid cells () were created to the north, and one additional row () was created to the south (Figure 4.5). Cells were drawn by first constructing two new horizontals which intersected with the western vertical from and the eastern vertical from at a distance of 20 m and 40 m from and . These new horizontals were then intersected with the verticals from , , and , and the new cells were drawn accordingly.

Since row XX is south of row I, it is unclear whether the roman numerals continue to increase past XI to the north. Unfortunately, the Byrsa volumes do not resolve this ambiguity. In this thesis, I assume that they increase at least up to XIII to the north.
Cells were drawn by first constructing a new horizontal which intersected with the western vertical from and the eastern vertical from at a distance of 20 m. This new horizontal was then intersected with the verticals from , , and , and the new cells were drawn accordingly.
Because the minor grid cells are not plotted on the basemap, they had to be entirely reconstructed from their description in the Byrsa volumes: measuring 55 m, they were created by subdividing each major grid cell into a 44 grid (illustrated in , , ; textual description in Byrsa III, 5 n. 1). Notably, the reconstructed major grid cells do not measure exactly 2020 m, nor are they exactly square; this is expected, because they were traced and reconstructed from a map that was hand-drawn, printed, and then scanned, each of which introduces error. Consequently, it is not possible to divide them evenly into 55 m minor grid cells. Instead, I divided each one into 16 quadrilaterals by drawing lines between the quadrants of opposite sides (Figure 4.6). This produced minor grid cells which were not precisely square, but were very close, and it spread out the error in the major grid cell among its constituent minor grid cells.
50
Out of 3808 reconstructed grid cells, just 548 (14%) had a side length that deviated from 5.00 m by more than 10 cm. None of the cells had a side length that deviated by more than 50 cm.

Other Maps

Every map of the site (that was useful for my purposes) was georeferenced relative to the reconstructed minor and major grid cells, except for (georeferenced relative to foundation piles in ), (georeferenced relative to the outlines of cisterns and walls in ), (georeferenced relative to the outlines of stones in ), (georeferenced relative to outlines of stones in ), (georeferenced relative to features in and ), (georeferenced relative to features in , , , , and ), (georeferenced relative to features in ), (georeferenced relative to features in ), and (georeferenced relative to features in ).
In total, these maps, which comprise my initial dataset, cover an overall area of 25608 m2, including 21248 m2 (or about 60%) of the hypothetical extents of the Roman Byrsa's monumental complex.
51
Areas are calculated within the Carthage / Nord Tunisie projected CRS, which uses the Clark 1880 ellipsoid (EPSG:7011). The area for the hypothetical extents of the complex does not include the region to the west of the cardo maximus, which is almost entirely unexcavated.
The extents of these maps are plotted in Figures 4.7, 4.8, and 4.9.

Chapter 5 Digitizing the Features

“on ne dira jamais assez combien l'absence d'archives a été préjudiciable à un développement rationnel de la recherche sur le sommet de Byrsa”
“we can never say enough how detrimental the absence of archives has been to the rational development of research on the summit of the Byrsa” (Gros in Byrsa III, 25)
“A large part of our failure to publish what we 'know' may result from the fact that we aren't sure what we do know or how we know it.” (Dever 1996, 42)
Digitizing features from the initial dataset required the resolution of four significant problems. First was the problem of scale: the dataset covers thousands of Roman and Punic features, and digitally tracing features on this scale is a major logistical challenge. Second is the problem of variability: many features are depicted on different maps in slightly different positions and orientations, requiring the evaluation of the different depictions and the citation of the map chosen. Third is the problem of ambiguous nomenclature: many features either have no (published) identifier, an ambiguous identifier (e.g., there is a “mur a” in both Punic block C and Punic block D), or several identifiers (e.g., “mur D” is sometimes called “mur Lapeyre”). Fourth is the problem of ambiguous ontology: on many maps, features found in situ are depicted alongside features that are conjectured (“reconstructed”) by the excavators. For some features, particularly the Roman substructural walls, there is often no visual distinction between the two, dissolving the line between evidence and interpretation.
I have attempted to resolve these problems in two ways: first, by limiting myself to digitizing only large structural features (walls, cisterns, etc) and mostly omitting architectural fragments; second, by creating a new organizational framework in which each feature is given a unique alphanumeric ID that encodes its ontological category. The details of this framework are explained in Section 2.2, but a very brief review may be helpful. The Feature ID codes are composed of type (wall, cistern, etc.), subtype (substructural wall D, façade wall, etc.), number (0001, 0002, etc.), and ontological codes (E - extant; R - reconstructed; H - hypothesized), which are combined into a Feature ID code of the form [type]-[subtype][####][Ontology], so that, for example, refers to an extant apse semicircular wall (or piece of a wall), and refers to a reconstructed cistern (or piece of a cistern).
A brief discussion about the accuracy and precision of my traces is warranted. Because I cannot ground-truth my results, I cannot build a reference dataset to compare them to, so I cannot definitively judge their accuracy. A rough comparison to satellite data from Google Earth (Figure 5.1) indicates that features are within about 2 m of their counterparts in the satellite images, which is very likely within the error bounds for the satellite imagery.
More useful is to consider the precision of my traces. In the interest of brevity, my assessment must be qualitative, rather than quantitative. The precision of my results can be evaluated from the internal consistency of my initial dataset, i.e., to what extent the boundaries of features shift between maps. Much of my initial dataset is consistent to

Figure 5.1: Outlines of the extant B and C foundation piles (in red) overlaid on satellite imagery of the Byrsa Hill from Google Earth. The outlines are about 2-3 m off of their counterparts in the images.
within 10 cm, most of it is consistent to within 20 cm, and all of it is consistent to within 30 cm. This is perhaps reflective of limitations inherent in my reconstruction of the reference grid (see Section 4.2), since the lines of the grid shown in the basemap were approximately 20-30 cm at scale. In summary, my feature traces are reasonably accurate and precise.

The Roman Features

The extant and reconstructable Roman architectural features on the Byrsa Hill mostly fall into two categories: substructures and perimeter structures. The first category includes substructural walls and foundation piles that supported above-ground structures and helped to contain the massive embankment created during the complex's initial construction. The second category includes structures that lined the complex's perimeter, such as the apses which supported the outermost retaining walls, and the stairs that provided access to the platform from the streets below. In the sections that follow, I will examine those features which are most relevant to this thesis, either because they date to the Augustan foundation, or because they replaced other such features. Because the foundation piles and substructural walls generally have previous IDs that are relatively unambiguous, (e.g., C17), I will use those IDs in my initial discussion and then introduce my new IDs at the end of each section.
It is often difficult to assign dates of construction to the Roman features, since most of the time they have already been excavated, then backfilled. Where stratigraphic context is no longer accessible, dating must proceed based on analyses of materials, construction, and the structural requirements of the complex, which can only give a general idea of the complex's development.
52
In general, it seems that the excavators of the French Mission were either unable or unwilling to deconstruct some of the architectural features, which would have allowed them to search for datable inclusions and describe their construction materials in detail. Consequently, their analyses are always comparative and point to construction dates that are very broad.
Features of interest in this thesis can usually be assigned to one of two phases. Features from Phase 1 were generally built during the initial construction program that began with the Augustan foundation and lasted for at least a decade or more. From the very beginning of the program, substructural and structural features were needed to direct, resist, and constrain the pressure exerted by the Augustan embankment, which generally towered 10-20 m over the level of the streets below. Structures from this phase were often constructed of rubble stones bound together with clay or earth, rubble stones that were reshaped and arranged in opus reticulatum, or large sandstone blocks taken from earlier Punic structures and arranged in opus quadratum or opus africanum. Features from Phase 2 were generally built during a large renovation and reconstruction program that took place in the second half of the 2nd century AD under the Antonine emperors. Under this program, the layout of the Byrsa was subtly reorganized to accommodate new buildings, including a temple in the SW corner and a large judicial basilica in the NE corner. The substructural features that were built or refurbished in this period are almost always in opus caementicium (Deneauve 1990, 143-145, retained in Ladjimi-Sebaï 2005, 68), and the structural features often contain stones which were clearly quarried by the Romans from sources not used during the Augustan foundation (e.g., El Haouaria and Hamilcar sandstone, Djebel Jelloud limestone).

5.1.1 The Walls

In the paragraphs below, the construction and dimensions of the substructural walls are discussed. In the interest of clarity, walls are presented in order from south to north. In the interest of brevity, only walls which belong to Phase 1, or replaced those walls, or are relevant for the reconstruction of those walls are presented.

5.1.1.1 Wall D (Figure 5.2)

Wall D (see Figure 5.2) was first investigated in the early 1930s by Lapeyre, who, under the impression that it was some sort of Punic fortification, apparently excavated along it for a length of over 80 m (1934, 341-343). When the wall was re-examined by the excavators of the French Mission (Carrié and Sanviti in Byrsa I, 106-113; Lancel in Byrsa II, 45-46), they found that Lapeyre had deliberately misrepresented its construction and
image: img/fig/12C__igures_Sitemap_Phase1_FocusWallD_WithLabels.png
Figure 5.2: Summary map of Wall D during Phase 1. CRS is Carthage / Nord Tunisie (EPSG:22391). Arrow indicates True North.
its dimensions in his description and his maps to better suit his interpretation.
53
For Carrié and Sanviti’s critiques of Lapeyre, see Byrsa I, 106, 111-112. His simplistic description (1934, 343) overemphasizes the wall’s toughness: “il est constitué essentiellement par de fortes chaînes composées de blocs de pierres de taille.” His map 1934, pl. 2; reproduced in ), which was drawn by Thouverey, depicts some fortifying buttresses along the length of the wall, none of which were observed by Carrié and Sanviti, and at least one of which simply could not have existed (Byrsa I, 110).
Wall D is of bipartite construction. The lower section, which in some places was set in a shallow foundation trench,
54
See e.g., profile , in which the foundation trench is comprised of layers 1 and 2a. The shallowness of this trench may be deceptive, since Lapeyre removed a significant amount of the surrounding soil.
was constructed using essentially the same materials and methods as the E piles: rubble stones from the Punic destruction layer bound together with clay.
55
As will be noted for the E piles (see n. 88), the binding agent is somewhat ambiguous. Carrié and Sanviti (in Byrsa I, 112) characterize it as “un simple mortier de terre.”
, The bottom of this section basically conformed to the topography of the layers immediately below the Punic destruction layer,
56
See Carrié and Sanviti (in Byrsa I, 112): “le plus souvent, ces particularités s'expliquent par l'adaptation des premières assises aux mouvements du terrain, qu'ils soient naturels (déclivité du sol) ou accidentels (fosse sépulcrale).” They further conclude (Byrsa I, 112), “recherchant pour s'asseoir le niveau de l'argile en place, [le mur] a dû s'adapter au relief naturel de la colline, et présente donc une élévation variable selon les endroits.”
but the way the wall conformed was variable: in some places the bottom course was arranged in a spiked formation, in others a stepped one (Byrsa I, 112). The upper section, which was generally thinner than the lower section (suggesting that it was not molded in a trench), was built heterogeneously, with segments of large sandstone blocks alternating with segments of rubble joined with clay (Byrsa I, 112-113). The interface between the upper and lower sections varies in elevation between 52.29 m and 51.11 m for a western segment (), tracking with the elevation of the bottom of the wall (Byrsa I, 113). The variance is not reported for the eastern segments.
Based on the stratigraphy, composition, and construction of wall D , Carrié and Sanviti concluded that the wall closely predated the Augustan embankment (Byrsa I, 113). However, their study only accounted for the westernmost extant segments; two eastern segments were investigated by Lancel (in Byrsa II, 45-46), and these complicate the picture. Profile seems to show that wall D’s foundation trench cuts not just the Punic destruction layer, but also the Augustan embankment above it, indicating that the wall was constructed after the embankment and causing Lancel to reject Carrié and Sanviti’s earlier conclusions.
While Lancel’s analysis is convincing for the eastern segments, I do not think it is necessarily applicable to the western segments, the closest of which is located over 20 m away. The western segments clearly conform very closely to the level of the pre-Punic destruction layers, and the interface between lower and upper sections roughly conforms to it, too. If the entire wall was built after the embankment, why would the builders have contoured the bottom of their trench to the Punic pavement and sub-pavement layers, and then tailored the level of the interface to match that contouring?
57
Especially when the rubble linked with clay construction was clearly capable of standing to a greater height, which is evident in its presence in the upper section.
The contouring and variable construction of the wall’s bottom is more consistent with a modular approach to the wall’s construction, in which different teams of workers under different supervision laid segments of the lower section in different places along a pre-determined centerline. A key advantage of this bipartite approach is its logistical flexibility: segments of the lower section could be scheduled for construction strategically, to meet the distribution of available building materials and the local structural demands of the embankment’s construction.
58
One of the key logistical challenges of the colony’s foundation was the procurement of building stone. Because Carthage possessed no nearby construction-grade quarries, the Punic ruins had to provide much of the stone used in the Augustan colony’s foundation. Thus, prior to (or, more likely, simultaneous with) construction, the city’s substantial Punic ruins were completely razed, and rubble from the Punic city’s destruction was cleared down to the final level of Punic pavement, in order to provide Roman colonists with space and building materials (Deneauve 1983; Gros 1990; Rakob 2000). Thus, the colony’s foundation must have required the deconstruction of vast stretches of architectural ruins, the movement of many hundreds of thousands of cubic meters of dirt and debris, and the clearing, sorting, and re-working of huge quantities of stone rubble, a procedure essentially unparalleled in the ancient Mediterranean world (Lancel 1995; Rakob 2000).
The wall’s upper section may have been constructed separately; certainly some segments of the wall were built in two stages at different points in the construction of the embankment, as the two layers of the construction trench in profile indicate. Construction of the upper section might also have been piecewise, since the arrangement of the large stone blocks varies between segments.
59
This hypothesis could be better evaluated if Carrié and Sanviti had reported the spacing between each of their evaluated segments. They may imply that the spacing is constant (“l’espacement d’axe à axe entre les éléments doubles est plus proche de 6 m que de 5.90 m ;” Byrsa I, 110), but if it was not constant then it would suggest that the upper section was constructed piecewise. Even if Carrié and Sanviti had reported these dimensions, they would not necessarily be representative of the entire wall, since their survey was limited by its fragmentary preservation.
In summary, the wall was probably constructed in individual segments, more or less in concert with the embankment, with the specific timing, order, and methods varying between different segments.
The width of wall D varied, but how is not exactly clear. Lapeyre (1934, 342) reports that it is on average 1 m, but he then reports that the blocks are generally 0.66 x 0.70 x 0.60 m, with some as large as 1.10 x 1.01 x 0.50 m or even 2 m (whether he means 2 m in length, width, or height is unclear) at the southeastern end—these dimensions clearly do not reflect an overall wall width of 1 m. Carrié and Sanviti do not report an average width, but one of their profiles () indicates a width of about 1.2 m for western segment (consistent with map ). Farther east, Lancel’s profile seems to indicate a width of about 1.8 m for the east side of .
60
Although it is obvious from photo that this segment still exists, I must consider it reconstructed because its extant outline is not plotted on any maps.
Unfortunately, Lancel’s cursory description of (about 1.0 m wide, located

even farther east) does not indicate whether the extant feature preserves the wall’s full width. I will assume that it does.

5.1.1.2 Wall G (Figure 5.3)

Wall G (see Figure 5.3) is very poorly published: I am not aware of any previous publication which provides even a cursory discussion of its construction and dimensions, with the exception of Deneauve (1990, 144), who briefly notes that is is made from the same materials, and using the same methods, as wall D and the E piles.
61
Wall G is also shown in photos of excavations of Punic block C in and .

of the site, , wall G is depicted as completely contiguous, but as maps and show, this is incorrect. Three small extant sections can be traced based on , , and . As with wall D, the intervening segments can be reconstructed based on assumptions of continuity, and the extents can be hypothesized based on the extents of the eastern and western Phase 1 apses, as in Deneauve's (1990, 151) proposed reconstruction. All of these sections are shown in Figure 5.3.

5.1.1.3 Wall H and an Associated Wall (Figure 5.4)

Wall H (see Figure 5.4) is mentioned only cursorily in the Byrsa volumes, and subsequent publications have added little to the picture. Deneauve (1990, 149) describes its construction as irregular stones (presumably rubble) joined with earth, which is clearly similar to the construction of wall D, and consequently he dates it to the Augustan foundation. It had a foundation pit nearly 1 m deep (Byrsa I, 94). There are only two extant segments of H in my initial dataset ( and ), but Deneauve, on the basis of (unpublished) excavations conducted to the north of those sections, argues that there were identical substructures 26 m north of them which mirrored the extant sections (1990, 150-151). I retain these reconstructions. The extant and reconstructed sections of this wall are shown in Figure 5.4.
The inner westward spurs of wall H are interrupted by a set of very large sandstone blocks (up to 2.5 m long, almost 1 m wide, almost 1 m high), which are linked together in courses (three are extant) by dovetail seals resting on bare earth (Gros in Byrsa I, 273-280; Deneauve 1990, 157). Two isolated pairs of similar blocks to the west of these courses indicate a westward continuation. Judging from map , this continuation extended at least 24 m west of the westernmost pair, as an excavation trench there revealed the foundation trench of the same wall. Based on the construction and dimensions of this wall, Deneauve suggests it served as the stylobate of a temple which is known to have existed in this area. Assuming symmetry about a central axis, Deneauve infers that this wall circled around behind the temple to meet up with the northern spurs of wall H. It is not clear how Deneauve determines the western boundary of this wall, but judging from , he sets it about 3.8 m to the east of the large Roman cistern. I retain his

reconstructions. The extant and reconstructed sections of this wall are shown in Figure 5.4.

5.1.1.4 Wall K (Figure 5.5)

On the other side of the stylobate wall, wall K (see Figure 5.5) perfectly resumed the track of the northern westward spur of , but in opus caementicium, rather than earth-bound rubble (Deneauve 1990, 149).
62
There is another “wall K” mentioned by Deneauve (in Byrsa I, 172) to the north of the Phase 2 temple in the southwest corner of the complex (see Section 5.1.1.7). Deneauve indicates that this wall is labeled on figure 1 of that report, but it is not. Judging from map (which cites plans made in 1960 by Pinard and 1975 by Borely), Deneauve is referring to the southern wall of the enclosure which was located along the cardo maximus to the north of the Phase 2 temple. In this map, wall H corresponds to the wall H discussed above. This suggests that the excavators of the French Mission adopted and adapted the ID systems used by their predecessors.
Deneauve interprets this dimensional continuity as evidence that wall K represents a Phase 2 alteration or reconstruction of previous Phase 1 foundations.
63
This Phase 1 substructural wall is in my dataset.
Following the same assumptions of symmetry as he used for the stylobate wall above, Deneauve posits an identical wall that mirrors wall K about the temple's central axis. I retain this reconstruction.
64
The Phase 2 substructural wall is in my dataset. The Phase 1 wall is .
The extant and reconstructed sections of this wall are shown in and Figure 5.5.

5.1.1.5 Wall M and Three Associated Walls (Figure 5.6)

Wall M (see Figure 5.6) was a substructural wall in opus caementicium running basically parallel to the cardo maximus about 28 m from the western side of the complex.
65
Wall M is sometimes labelled as two adjacent walls M1 and M2 (see e.g., ).
Extant segments of this wall can be seen e.g., in maps , , and . At wall M’s southern end, a second wall, also in opus caementicium (Deneauve 1983, 95), continued perpendicularly to meet the edge of the cardo maximus. Extant segments of this second wall are visible in and . Additional excavations found segments of a third wall (to the west) and a fourth wall (to the north), which joined the previous two walls into a rectangular enclosure adjacent to the cardo maximus.
66
This building has been preliminarily judged to be a library. Deneauve (1990, 154) proposed this assignment based on the building's location and the thickness of the the east and west walls (i.e., wall M and the second associated wall). Gros (1997, 349) took up this assignment and provided some textual evidence for it. Ladjimi-Sebaï (2005, 73) and Ennabli (2020, 93) retain this assignment.
Unfortunately, the extant segments of the third and fourth walls do not appear to have been published in a reasonably georeferenceable fashion. They are shown on several low-quality
image: img/fig/16C__itemap_Phase2_FocusWallMAndAssoc_WithLabels.png

georeferenceable maps (of which the best is ),
67
The extant segments of the western and northern walls of the enclosure are shown in (printed upside down and in very low quality) which appears visually similar to—and is perhaps reproduced by—Deneauve (1983, 102 fig. 3; also upside down and in worse quality). This second map (Deneauve 1983, 102 fig. 3) seems to have been reproduced in much higher quality in , which in turn has recently been reproduced with some annotations and minor (unmentioned!) modifications by Ennabli (2020, 80 fig. 35). seems closely related to Morel's map (2011b, fig. 1), but the nature of this relation is unclear. The close relationship between these maps is supported by their identical conflation of extant and reconstructed features: all of them show (in solid colors or solid outlines) a complete alignment of 13 apses in the southwest corner and an almost complete alignment of 11 apses in the northeast corner, when it is clear that for each alignment no more than five apses have extant remains (see Section 5.1.3.1). The maps use dotted lines to join solid-colored segments of the substructural walls, but many of these solid-colored segments do not appear on any other maps.
but these maps are invariably printed at a very small scale, and they diverge from the rest of my initial dataset by at least 1-2 m.
68
The agreement between my initial dataset and is much better for certain features, most notably the foundation piles, which generally agree within 0.5 m and never diverge by more than 1 m. Nevertheless, the lack of consistency in the degree of agreement precludes serious consideration of this map for my purposes.
I do take the western extent of the third wall from , since this is a critical constraint that no other map can provide, but every other aspect of these walls must be reconstructed.
I reconstructed wall M as follows. I assume that the northern side was flush with the line of the southern façade of the eastern basilica in (see Section 5.1.3.4),
69
This line is referred to as in Appendix C.
and that it was 4.0 m wide (following Deneauve 1983, 105 fig. 8). I reconstruct the intervening segment between and based on an assumption of continuity. I assume that the southern extent of the wall is given by , and that the northern extent is flush with the line from the south façade of the basilica.
70
This line is referred to as axis of reconstruction in Appendix C.
.
I reconstructed the second (southern) wall as follows. I assume that the west side was colinear with the west side of the third wall, and that the wall maintained a constant width of about 2.1 m, based on the width of the west side of .
I reconstructed the third (western) wall as follows. I assumed that its south side abutted the north face of the second wall, and that its north side abutted the south face of the fourth wall. I assume the west side followed the line shown in .
71
More precisely, I assume that the west side was flush with the line stretching from the southwest corner of the southwest corner room in (see Section 5.1.3.1) to the northwest corner of the third wall in . This line is referred to as in Appendix C.
I assume the wall had a constant width of 4.4 m, following Deneauve (1983, 95).
I reconstructed the fourth (northern) wall as follows. I assumed that the north side was flush with the line of the south façade of the basilica in .
72
On this line, see n. 69. This assumption is visually consistent with Deneauve’s schematic illustration (1983, 105 fig. 8), but seems to differ from Gros’ map ().
I assumed that the east side had a width of 2.1 m as shown in Deneauve (1983, 105 fig. 8). I assumed that the west side was colinear with the west side of the third wall, and that its width was equal to that of the east side.

Deneauve conducted excavations in a handful of locations on the north side of the central square (very near the side walls of the modern museum), which uncovered the remains of substructural walls that paralleled walls D, F, and G, which he termed walls D’, F’, and G’ (see Figures 5.7 and 5.8). The results of these excavations were only published in one cursory article (Deneauve 1983),
73
The excavations in this area are very occasionally mentioned elsewhere, e.g., Byrsa III, 46 n. 6, 140.
which provides very little information about the walls’ locations, dimensions, and construction. The schematic site plan included in this article (Deneauve 1983, 105 fig. 8) is drawn to scale (specifically 1/200), but it is discontinuous and it has no reference grid or other feature which could be used to georeference it.
74
In Deneauve’s map, the excavation trench at the southwest corner of the basilica’s walls does not seem to be included on any other published map of this area, even though the excavation there was conducted in 1983 or 1982, and the last published maps of this area (e.g., ) are from 1985 (though it did take the publisher EFR 1-2 years to release the volume—this was acknowledged by Gros (1982, 636-637 n. 3). The sounding at the northeast corner of the large enclosure adjacent to the cardo maximus found an extant segment of wall M, but again, this excavation trench does not appear on any other accurate, georeferenceable map (see Section 5.1.1.5 and n. 67).

The excavators uncovered the remains of five segments of wall D’. Of these, the westernmost abutted the north wall of the large enclosure adjacent to the cardo maximus (, see Section 5.1.1.5) and the easternmost seems to have been aligned (and perhaps continuous) with the southern façade wall of the basilica (Deneauve 1983, 105 fig. 8).
75
The connection between these two walls is ambiguous, in part because it is not clear precisely what feature Deneauve found in the southwest of the basilica. Deneauve only says “un sondage a permis de retrouver les tranchées de fondations correspondant à l'angle sud-ouest de la basilique exactement à l'endroit prévu, mais surtout de constater que celle de son mur latéral sud se prolongeait vers ‘l'ouest au-delà dé l'édifice. L'extension des recherches n’étant pas possible à cet emplacement, un autre sondage a été ouvert à quelques mètres, à l'ouest. Il a confirmé l'alignement de la tranchée de fondation de ce mur D’, celui de l'égout qui longeait le portique et celui des murs F’ et G’” (1983, 97; italics are mine). It is not clear if Deneauve is talking about a foundation pit in negative (i.e., whose original contents were removed prior to excavation), or a foundation constructed in the form of a trench, essentially the same as a substructural wall; I assumed that it was the latter. It is also unclear whether these foundation trenches in the southwest corner of the basilica belong to the Antonine basilica itself, or to an earlier construction. On Deneauve's plan (1983, 105 fig. 8), wall D’ and the trenches appear to be perfectly aligned and of the same width, a point which Deneauve also notes (1983, 98).
The width of wall D’, judging from the plan, varies between 1.0 and 1.2 m; in my reconstruction, I assumed a width of 1.1 m. No information is given about the construction of this wall, but Deneauve dates it to Phase 1 (1983, 96).
The excavators uncovered the remains of two segments of walls F’ and G’, which ran parallel to each other (F’ abutting the north side of G’) to the south of and parallel to wall D’.
76
The eastern segments appear fragmentary in Deneauve's plan, but he does not comment on this in his discussion.
For the western segment (which according to the plan was located 9.0 m east of wall M), judging from the plan, the interior distance between D’ and F’ was about 9.5 m, F’ was about 1.5 m wide, and G’ was about 1.7 m wide (Deneauve 1983, 105 fig. 8). For the eastern segment (which according to the plan was located 10.0 m east of the line of the Basilica’s western façade), judging from the plan (Deneauve 1983, 105 fig. 8), the interior distance between D’ and F’ was about 9.8 m, F’ was about 1.3 m wide, and G’ was about 1.7 m wide. The interior distance is almost identical to that separating wall D from wall F (Deneauve 1983, 96). No information is given about the construction of these walls, but Deneauve dates G’ to Phase 1 and F’ to Phase 2 (1983, 96). I consider these walls to be reconstructed within the bounds of the two segments. I hypothesized their original eastward and westward extents based on assumptions of symmetry with their southern counterparts (this is consistent with Deneauve's reconstructions in , ).

5.1.1.7 Other Walls

On the north side of wall D’, the excavators found opus signinum paving (Deneauve 1983, 97). On the eastern side of wall D’, the excavators found that this paving was delimited by a foundation pit (Figure 5.9), which Deneauve (1983, 97) notes is aligned with similar remains found 60 m to the west during repair work to the museum.
77
Once again, it is unclear if this foundation pit (“fosse de fondation;” Deneauve 1983, 97) is the remains of a foundation in negative, or an extant segment of a substructural wall molded in a pit (see n. 75). Once again, I assume the latter.
Judging from the plan, the interior distance between this pit and wall D’ was about 10.1 m and the width of the pit was about 2.3 m (Deneauve 1983, 105 fig. 8). Deneauve hypothesizes that the enclosed area constituted a portico opening onto the forum (1983, 97). No information is given about the construction of this wall. Deneauve (1983, 98) does not directly suggest a function, but implies that the wall may have served as a stylobate. To the west of Deneauve’s excavation, more remains (probably) belonging to this substructure were found in during renovation work in the modern museum (Byrsa III, 140).
image: img/fig/19C__Sitemap_Phase2_FocusPorticoSubst_WithLabels.png
Figure 5.9: Summary map of portico substructures during Phase 2. CRS is Carthage / Nord Tunisie (EPSG:22391). Arrow indicates True North.
Consequently, I consider this wall to be reconstructed from this point east (), and hypothesized from this point west ().
The remains of a parallel substructure, which probably served as the stylobate for another portico, were found adjacent to the northwest side of the basilica (Deneauve 1983, 98; Byrsa III, 140). No map of these remains has been published. The width of this substructure is given as 1.75 m (Deneauve 1983, 98), which yields an interior distance of 58.94 m between it and the stylobate of the southern portico.
78
Deneauve (1983, 98) provides a slightly different interior distance between the stylobates of 58.78 m. While the difference between these two distances is within my margin of error, an explanation is included here for the sake of transparency. This interior distance assumes that the north and south stylobates are perfectly parallel, that their interior dimensions are identical, that the distance between the north face of D’ and the north face of the southern stylobate is 12.25 m, and that the interior distance between the north and south walls of the basilica is 83.28 m. I retain the first two assumptions. I do not retain the third assumption—instead I retain my measurements of the interior distance and stylobate width from the plan (Deneauve 1983, 105 fig. 8), yielding a figure of 10.1 + 2.3 = 12.4 m; while Deneauve’s figure of 12.25 sounds more precise, he does not include the individual measurements from which he calculated it. I do not retain the fourth assumption, instead opting for the figure yielded by my georeferenced map : 83.74 m. Thus, the interior distance between the two stylobates is given by 83.74 – 2 12.4 = 58.94 m.
To the west of Deneauve’s excavation, more remains (probably) belonging to this substructure were found in -13 during renovation work in the modern museum (Byrsa III, 140). Consequently, I consider this wall to be reconstructed from this point east (), and hypothesized from this point west ().
A little over 10 m past the eastern ends of this northern portico,

This measurement is based on the reconstruction of the basilica shown in .
in excavators uncovered a segment of a perpendicular substructural wall which supported the basilica’s western alignment of columns ( see Figure 5.10; Byrsa III, 52). The width of the remains was 2.40-2.45 m, and the wall appears to have continued under the entire alignment of columns (Byrsa III, 52). Neither the extant segment nor the reconstructed segments of this wall are labeled on the maps of Byrsa III, and the former is visually very similar to

adjacent later constructions. I assume that the north and south ends of this wall originally abutted the north and south façade walls of the basilica (see Section 5.1.3.4). As far as I am aware, there is no published description of the wall’s mode or date of construction;
80
On the one hand, the lack of a date is not entirely surprising, since the excavators, working in the garden of the modern museum, would likely not have been allowed to dig as low as the foundation trench. On the other hand, the lack of a description of construction is very disappointing, since it was obviously known to the excavators and it could have provided a rough idea of the dating.
I will assume that the wall dates to Phase 2 and that it was constructed similarly to those another substructural wall which was found about 21 m farther east. This eastern wall is structurally related to the apses of the eastern perimeter, so it will be discussed in Section 5.1.3.4.
There are several additional sets of substructural walls that deserve mention. According to Deneauve’s reconstructions (, ), on the east side of the Byrsa, three north-south substructural walls are shown adjacent to (or under) two staircases which provided access to the cardo IV east below (see Figure 5.11).
81
It is not totally clear if these staircases should be considered “hypothesized” or “reconstructed”—see n. 142.
Two walls are adjacent to the southern staircase (), and one wall is adjacent to the northern staircase (). As of this writing, I have not been able to find any published description of these walls. The southern pair is also shown in , but it is unclear if it is directly attested or just reconstructed.
82
The southern pair is also visible in basically the same position and orientation on and related maps, but its ontological category cannot be reliably determined from them (see n. 67).
Based on and , it appears that the eastern wall of the southern pair abuts wall G and belongs to Phase 1, while the western wall abuts wall F and belongs to Phase 2. The northern wall is shown in no other maps. Some of its remains may have been encountered during Deneauve’s (1983, 96) excavation in the southwest corner of the basilica (which his reconstruction calls for it to abut), but his

publication does not mention them.
83
Map might appear to show some excavations at the southern end of the northern pair, but a comparison to recent satellite imagery from Google Earth shows that these are actually a modern building.
In Deneauve’s Phase 1 reconstruction (), the wall seems to abut wall G’, and in the Phase 2 reconstruction (), it seems to abut wall F’. I will assume that F’ was built around this wall, so that its dimensions did not change in Phase 2. I will call the southern pair reconstructed, and the northern wall hypothesized. The relationship between these walls and the adjacent substructural walls will be further discussed in Section 5.1.3.4.
More certain than those pairs of walls are the substructures which appear to have supported a Phase 2 temple in the southwestern corner of the complex (see Figure 5.12).
84
A similar temple has been posited opposite this one, in the southeast corner of the complex (Byrsa I, 135; mentioned also in Ladjimi-Sebaï 2005, 90). No remains of this temple have been published, so I will not consider it.
These walls were constructed in opus caementicium, with an opus quadratum crosswall (which the excavators call Es) giving them the shape of an H (Byrsa I, 168-172). The UNESCO-backed excavations in this area divided the structure into 5 walls: O (west), N (north), S (south), S1 (smaller wall to the south abutting O), and N1 (smaller wall to the north abutting O). Based on maps and , it appears that N, S, and O may actually be continuous with one another (i.e., part of a single unified construction), but this is not mentioned in the excavation report, so I will assume that they are separate.
Finally, there was a retaining wall that was braced by the apses along the south side of the complex. Since this wall is in close structural relation with these apses and other south perimeter structures, it will be discussed in Section 5.1.3.2.

5.1.2 The Foundation Piles

Excavations on the southern slope of the Byrsa have uncovered three rows of Roman foundation piles (B, C, and E) running parallel to the axis of the decumanus maximus and spaced 11-12 m apart.
85
11.40 m between the rows B and C, 12.10 m between rows C and E (measurements taken from Byrsa I, 132).
Each row is composed of up to a few dozen piles, spaced 4-5 m apart, thrust into (or through) the Augustan embankment. These piles served two primary purposes: they assisted in retaining the massive weight of the Augustan embankment (which would otherwise have overwhelmed the support structures lining the decumanus I south), and they served as substructures for walls and other constructions on the surface of the embankment.
These piles stretch almost the entire length of the southern slope of the hill, and given that almost no above-ground Roman structures remained when archaeological excavations began, the piles were likely some of the first Roman features to be discovered.
86
The piles have been attested in publications since at least the 1930s, but they were probably known much earlier. Seventeen of the C piles (and apparently two of the B piles) were known to Lapeyre—see Thouverey’s map in Lapeyre (1934, pl. 2; this map is reproduced in Byrsa I, 24). It is very likely that Beulé encountered piles during his excavations in the southeast corner of the complex, but he does not mention them and as far as I can tell, no evidence of them has survived.
It is unfortunate, then, that no comparative study of the individual piles has ever been published. Instead, brief descriptions are scattered across the excavation reports of Lapeyre, Ferron and Pinard, and the authors of the Byrsa volumes. In the following paragraphs, I draw from the general observations given in these reports to summarize the existing data for the piles’ location, composition, and chronology.

5.1.2.1 The E Piles (Figure 5.13)

The northernmost row contains six clearly extant piles (E1 through E6) and physical traces of three others (Eh, El, Ee), and a very likely location for one more (Ea).
87
There is a gap in between E6 and E1 (at grid cells , 3) suggestive of a missing pile. The report on the center of the southern slope (“sector B”) that is published in Byrsa I describes traces of three missing piles in and (Byrsa I, 129-130); of these three piles, only Eh and El are labeled on a map (see ), even though all of them also appear on and Eh and Ee appear on . In the conclusions to this report, the authors mention an additional missing pile Ea (not discussed elsewhere), which they suggest must have been included in a later foundation structure that was removed during the excavations of Ferron and Pinard (Byrsa I, 133). This structure is visible in the published plan of the 1953-54 excavations (Ferron and Pinard (1955, pl. 2)), and it is outlined with a dotted line in . Based on the latter, it is clear that the hypothesized pile Ea would have occupied the gap between E6 and E1.
These piles are roughly constructed from irregular chunks of Ariana limestone and other stones from the Punic destruction layer that are joined together with clay.
88
For a cursory description of the stones used in construction, see Carrié and Sanviti (in Byrsa I, 129, 132-133) and Deneauve and Villedieu (in Byrsa I, 191).The identity of the bonding agent is more ambiguous: Carrié and Sanviti (in Byrsa I, 129) say that the stones are “simplement liés à l’argile” (“simply bound with clay”), while Ferron and Pinard (1960, 89) and Deneauve (1990, 144) describe them as bound with “terre,” which can mean either soil or clay.
Piles E1, E2, and E3

display a bipartite morphology in which their lower sections appear roughly constructed but relatively straight, while their upper sections appear more exactly constructed but lean towards the east (Byrsa I, 132-133). This suggests that the E piles were constructed by digging foundation pits into (and in the case of Eh, through) the Punic destruction layers, filling the pits with irregular chunks of Ariana limestone and other stones from the Punic remains, intermixed with dirt or clay, and then placing stones in more regular patterns on top of the filled pits. The rough mode of construction, which closely resembles that of wall D, prompted Carrié and Sanviti to conclude that the E piles are contemporary with wall D and shortly predate the Augustan embankment (Byrsa I, 132-133).
In modeling the Augustan Byrsa, it is necessary to reconstruct some additional piles and sections of piles in this row and to hypothesize several more. The extant, reconstructed, and hypothetical features in row E are summarized in Table 5.1 and Figure 5.13. Several of the extant E piles are clearly fragmentary, so I have correspondingly reconstructed some sections: these are , , , , , and . Based on the spacing of the E piles and their proximity to wall D, it seems likely that the E piles served as supports for a colonnade (Byrsa I, 135). As such, it is reasonable to reconstruct additional piles in the gaps between the extant ones: these are , , , , , and (pile Ea). Given the extensions of the colonnade proposed by Deneauve (1990),

we can hypothesize 4 additional piles to the west of El (): these are , ,

, and .

5.1.2.2 The C Piles (Figure 5.14)

The central row contains 21 extant piles (C1 through C21), which are constructed of opus caementicium with small re-used rubble stones whose dressing resembles that of opus reticulatum facing.
90
For the identification of opus caementicium, see Lancel (in Byrsa I, 51-52) and Lapeyre (1934, 343). For the stones see Byrsa I, 74. This assessment is somewhat tenuous. From Lancel’s description (in Byrsa I, 74), it is unclear if these re-used stones are inclusions or facing: “les piles […] comportment dans leur maçonnerie des éléments de remploi, notamment des petits moellons de parement d’opus reticulatum.” Many photographs of the C piles appear to show masonry facing, or at least the imprints of facing that has been lost, but the resolution of the photos is too low to be sure (see e.g., photos , and , , ). Photo seems to show no facing on C7, but this may be contradicted by corresponding profile . Photo seems to show facing for several meters below the top of C17, which then vanishes as the pile widens toward its base; this seems to be reproduced in the corresponding profile drawing . Photo seems to show a similar bipartite construction for piles C15, C14, and C13 (unlabeled in photo—these are the piles 3rd, 4th, and 5th from the right side of the photo, counting inclusively from the corner of C17 shown at far right). It is possible that the wide cladding around the lower parts of these piles is actually soil that the excavators left in place as a support, rather than part of the piles themselves. Likewise, it is possible that the apparent courses of stone or brick-work along the top parts of the piles are actually artifacts of the field techniques used to excavate them. Unfortunately, no explanation for either is given. Ladjimi-Sebaï (2005, 47) directly contradicts this assessment, claiming that the C piles are constructed in opus incertum.
This composition is consistent with a date after the initial Augustan

construction of the Byrsa complex (Byrsa I, 74; Deneauve 1990, 144). The stratigraphy and morphology of the piles support this hypothesis by helping to post-date the piles relative to the Augustan embankment. Studies of the stratigraphy around the piles show no evidence of foundation pits distinct from the piles themselves, and the piles tend to widen slightly toward the top (Byrsa I, 74).
91
Some of the photographs in the Byrsa volumes contradict this assessment of the pile morphology. For example, photo shows that C17 widens at the bottom, and shows a similar morphology for piles C13, C14, and C15 (see note 90). If the lower cladding is not actually part of the piles, they do widen toward the top. However, other piles in row C without such cladding are shown to narrow towards the top in photos and .
Both of these observations suggest that the piles were constructed by digging deep shafts through the Augustan embankment and pouring a mix of concrete and stone inclusions into the shafts.
92
Deneauve (in Byrsa I, 51-52) seems to indicate that the C piles generally cross the entire embankment, but it is not clear if this statement applies to all of them. If the piles had facing, the concrete pouring would have been preceded by the laying of masonry (see note 90).
The C piles were (originally?) joined together with additional stonework to form substructural wall C.
93
This wall was clearly visible to Lapeyre, and is shown in his plan to run unbroken for a length of almost 100 m (1934, pl. 2; reproduced in ). This wall will not be discussed as it is not relevant for the Augustan layout of the site.
The piles are contiguous with the H-shaped foundations on the SW corner of the hill, which also post-date the Augustan embankment and likely belong to Phase 2.
94
These foundations are often called the “quadrilateral” in older publications. This is the same period of reorganization which produced the final layout of the basilical structure in the NE corner of the Byrsa (for discussion, see Byrsa III).
It is possible that the southwest foundations and the C piles are contemporary; Carrié and Sanviti seem to imply that the date of the southwest foundations informs the date of the piles,
95
Carrié and Sanviti (in Byrsa I, 132): “en ce qui concerne le mur C, sa fonction et sa date ont été éclairées par le dégagement d’un temple (à l’ouest de notre secteur) dont l’alignement des piles C prolonge la fondation nord.”
and refer the reader to the following chapter (a report on the excavations on the SW corner) for further discussion (Byrsa I, 132). Unfortunately, while that report acknowledges that the C piles are contiguous with the SW foundations (Byrsa I, 170), it does not discuss their relationship.
It seems likely that the C piles originally extended farther eastward, since the last extant one, C21, is over 40 m away from the east side of the complex. I hypothesize that there were an additional five C piles to the east of C21, sized about 1.8 1.8 m, spaced about 4.4 m apart, and following the same alignment.
96
This is the average spacing of the five easternmost C piles. The alignment used was based on the line between the centers of C17 and C21. The sizing is the same as that assumed for the hypothesized B and E piles.
The extant, reconstructed, and hypothesized C piles are presented in Table 5.2 and Figure 5.14.

The southernmost row contains at least 15 extant piles (B1 through B15), with two other possible piles to the east of B15.
97
There are two oblong features in grid cells , , 6, 7 of map that appear to be traces two additional B piles, but there are no other detailed maps of this area that can completely corroborate this assessment. On map , they are depicted identically to other B piles, so hereafter I will assume that they are unlabeled B piles. I have assigned them the IDs and .
These were constructed differently from the piles in the other two rows, with small pieces of rubble (including some stones that seem to come from destroyed Punic buildings) surrounded by white-grey mortar (Byrsa I, 133).
98
Carrié and Sanviti actually say that the stones are joined with cement (Byrsa I, 133): “petits moellons noyés dans un ciment gris blanchâtre.” In contrast, Lancel (in Byrsa I, 74) characterizes the bonding agent used in these piles as “mortier” (mortar). As with the C piles, Ladjimi-Sebaï (2005, 47) claims that the B piles are constructed in opus incertum. I follow Lancel and assume that the bonding agent is mortar.
Their morphology is also quite different, flaring widely at the base (see photos , ).
99
Although it is possible that this flaring is actually earthen supports left by the excavators (see note 90).
These piles are much shallower than the E and C piles; some do not even make contact with the Punic destruction layers, indicating that the piles post-date the Augustan embankment. Carrié and Sanviti infer that the Punic inclusions were used in other Roman structures before the B piles, prompting them to conclude that the B piles were constructed from the remains of decommissioned Roman structures after the complex's initial construction (Byrsa I, 133). More precise dates for the piles have been proposed, but these are controversial.
100
Carrié and Sanviti decline to offer a more precise date, but suggest that the construction of the piles resembles that of the later Roman walls found on the area of preserved stratigraphy ironically termed “Butte Lapeyre” (Byrsa I, 133). In their discussion of these walls—which they describe as stones joined with lime mortar (c.f. their description of “ciment” in the B piles; see n. 98)—they suggest a dating “postérieurement à l'abandon de la plateforme supérieure de la colline comme centre politico-religieux de la cité, et à la désaffectation des édifices de type public,” but also see no relation “avec la période tardo-romaine et byzantine” (Byrsa I, 100-101). Lancel (Byrsa I, 74) only suggests that the B piles postdate the C piles. Deneauve (1983, 94) says that the B piles are very late, probably Byzantine. Ladjimi-Sebaï seems doubtful of this dating, at one point suggesting that both the B piles and the C piles may date to the Augustan era. In her discussion of sector B, she refers to them as “la double série de piles de fondations en opus incertum datant de l’aménagement de la colline à l’époque augustéenne” (2005, 47). Further on, she qualifies this assessment of the C piles (“les piles de fondations C semblent postérieures;” Ladjimi-Sebaï 2005, 89) but retains her skepticism of the B piles (“quant aux piles B, elles pourraient avoir été installées après la désaffectation des constructions romaines, et il n’est pas possible de préciser leur date de construction;” Ladjimi-Sebaï 2005, 89-90).

While the C piles likely replaced earlier Augustan foundations, the case is not so clear for the B piles. As Deneauve and Villedieu point out (in Byrsa I, 171), supports would have been necessary from the beginning of the complex to hold back the tremendous mass of the embankment—not just in the southwest corner, but also all the way along the southern slope. Out of all of the foundation piles, the B piles had to make up the greatest difference in elevation, which ranged from 13 to 20 m over the eastern third of the south slope.
101
See topographical points e.g., in .
The idea of constructing piles, from unworked rubble stones, on a footprint of about 1.8 1.8 m, to a height of 13-20 m before surrounding them with an embankment seems rather impractical. I think it is reasonable to suggest that the B piles were built during or immediately after the construction of the Augustan embankment, in order to minimize the risk of structural failure. The fact that some of them do not touch the Punic destruction layers has no bearing on their dating, nor does their morphology. In the absence of more information about the pile's inclusions and the strata located below them, I think an Augustan dating is possible, and perhaps probable.
The extant, reconstructed, and hypothesized B piles are presented in Table 5.3 and Figure 5.15.
If we date the B piles to Phase 1, then it is reasonable to assume that they would have originally extended to some point close to the extrados of the southwestern apses, since

some sort of substructure was necessary to help retain the embankment (Byrsa I, 171) and the substructural walls in opus caementicium had not yet been built. This westward extent of the B piles can be indirectly hypothesized based on the layout and construction of these later walls, despite significant gaps in their published data (see Figure 5.16).
102
It is difficult to determine the development of this set of substructures because of problems of publication. First excavated in the early 1890s by Delattre, who considered them some sort of bastion (see Byrsa I, 51 n. 58), they were cleared in places below the level of the foundations, causing some of the walls to collapse. During the UNESCO-backed excavations of the 1970s, they were re-excavated and documented more systematically, albeit very sparsely.
It seems clear that the opus quadratum wall Es was constructed before the other opus caementicium walls N, S, and O, and that its north and south ends, which were ultimately encased in walls N and S, originally spanned both of their widths.
103
This is evident in maps and , where Es is clearly shown to cut wall S (shown also in photo ), and the start of a similar cut in wall N can also be seen. I assume that the northern cut spanned almost the entire width of wall N.
While it is likely that wall Es served an active substructural role in the final building above it, its first purpose might very well have been as a temporary retaining wall. The pouring of walls N and S could not proceed without the destruction of vaults, façade walls, rectilinear walls, and semicircular walls in the first and fourth apses of the southwestern alignment (Byrsa I, 169),

which would have destabilized the second and third apses,

compromising the integrity of the entire Phase 1 support system in an area where the embankment rose 5 – 6 m above the level of apse floors.
106
For elevations see the reconstructed profile .
The installation of Es would have alleviated that problem. Walls N1 () and S1 () appear to have been constructed after walls N, S, and O, and they braced the semicircular walls of the second and third apses against wall O, which kept the semicircular walls upright after their vaults, rectilinear walls, and façade walls were dismantled.
107
It is unclear if this dismantling happened before or after the construction of walls N1 and S1, but after seems more likely to me, since that would have ensured the continued structural integrity of the semicircular walls. Deneauve and Villedieu (in Byrsa I, 169) suggest that the semicircular walls were left in place to help withstand the embankment, and while the bracing function of N1 and S1 seem to support this, I think it is more likely that their primary role was to support the structure above. The pressure from the embankment between them and Es would not have been very great, and it would have decreased dramatically once their interiors were filled up with earth.
Based on the published data, It seems that walls N and S may each have been constructed in two sections: on map , Es's cut into S appears to end just 20 cm short of the outer edge of S (which is within the range of precision of my initial dataset), and the western extant piece of S () ends immediately after that. Moreover, the northwest corner of abruptly ends in a 90-degree angle cut toward Es. This suggests that both N and S may have been poured in two segments, with the first segment stretching between O and Es, and the second segment extending east from Es. Groundtruthing could help confirm or disprove this hypothesis, since it could show whether the matrix of was continuous with the matrix of .
Why was wall Es placed where it was, about 2.5 m back from the extrados of the southwestern apses? The simplest answer would be that it was placed according to the initial plans of the 2nd-century architect who designed the temple, but this answer seems unlikely. The architect must have been aware that there were substructures embedded under the Augustan platform, but they likely did not know their precise locations and dimensions. These would have needed to be determined before they could begin laying the foundations. I hypothesize that the B piles originally extended to a point abutting the east side of Es, whose location was chosen to mark the end of that extension. The architect could then have been confident that Es would function as a temporary replacement for the southwestern support system, allowing the workers to safely decommission the first four apses in the southwest alignment.
108
This alignment is termed “Series 1” in Section 5.1.3.1.
It is possible that the same would be true for the Phase 1 substructure that was replaced by the C piles.
109
In maps and , two adjacent stones appear about 4 m west of pile C1, with a very long stone laid between them and C1. These stones are completely unremarked in the literature, but it would be worth groundtruthing to see if they actually formed part of an earlier support that was encased in cement during the construction of the temple. Lapeyre (1934, pl. 2) seems to show another C pile on the west side of this pair of stones, but no there is no sign of this pile in the later maps.
Notably, this hypothesis would align the westernmost B pile (and perhaps Phase 1 C pile) with the westernmost E pile. While this certainly does not prove the hypothesis, it does make it more attractive, from an engineering standpoint. Thus, I follow this hypothesis and hypothesize an additional seven piles in row B, each about 1.8 1.8 m and spaced about 3.9 m apart (consistent with the extant piles near them), following the same alignment.
It seems likely that the B piles originally extended farther eastward, since the last extant one, , is over 40 m away from the east side of the complex. I hypothesize that there were an additional six C piles to the east of C21, sized about 1.8 1.8 m, spaced about 4.8 m apart, and following the same general alignment as the rest of the row.
110
This is the average spacing of the five easternmost B piles. The alignment used was based on the line between the centers of B1 and B7. The sizing is the same as that assumed for the hypothesized C and E piles.

5.1.2.4 Other Piles

During the excavation of the northern portico of the central square (see Section 5.1.1.6), Deneauve (1983, 96) found the remains of a column sub-base about midway between walls G' and D', leading him to suggest that the northern portico had a central row of
image: img/fig/27C__s_Sitemap_Phase1_FocusOtherPiles_WithLabels.png
Figure 5.17: Summary map of the other piles. CRS is Carthage / Nord Tunisie (EPSG:22391). Arrow indicates True North.
columns similar to the southern portico (see Figure 5.17). This sub-base is not reliably geolocatable. It is somewhat unclear if Deneauve thought there was a row of foundation piles in the northern portico—he makes no such hypothesis in his text, but his plan (1983, 105 fig. 8) specifically labels this sub-base as part of a hypothetical row of E' piles. This hypothesis seems to be retained in Deneauve's Phase 1 reconstruction of the site (), which has a row of 19 squares in the southern portico and an almost identical row in the northern portico.
111
It is possible that these squares are meant to indicate column bases, but Deneauve does not say one way or another. Notably, the squares in the northern portico are not all aligned with each other: the third and sixth squares from the eastern end are shifted to the south. The spacing between these two squares is a little over 16 m, which seems roughly equivalent to the spacing between the two squares shown in Deneauve's plan (1983, 105 fig. 8). This suggests that Deneauve may have actually found two sub-bases, rather than the one that he reports (1983, 96). One problem with this theory is that the distance between the eastern sub-base and the line of the western façade of the basilica in the plan (about 9.8 m) does not match the distance in the reconstruction (about 14.7 m).
Consequently, I will assume that Deneauve hypothesized a row of foundation piles in the northern portico, whose dimensions and spacing were very similar to the E piles. I retain Deneauve's hypothesis, and I further hypothesize that these piles were basically square, about 1.8 1.8 m, stretched between the eastern and western limits given in (slightly adjusted north or south to be midway between walls G' and D'), with a spacing of about 5.3 m. These piles are given the subtype 'X'.

5.1.3 The Perimeter Structures

No Roman features have been more enduringly popular in the minds of western archaeologists than the structures which lined the perimeter of the Byrsa complex. This has created several notable conditions. Temporally, the perimeter structures have the greatest depth of scholarship, ranging from Beulé's foray in 1859 to the first—and, so far as I can tell, only—systematic study of their architecture, conducted by the excavators of the French Mission in the 1970s and 80s. Physically, they are the worst preserved, with the vast majority of the apses and façade walls completely destroyed by prior excavations, early modern and modern constructions, and spoliation. Ontologically, they are very opaque, with large sections of the perimeter so poorly documented that the distinctions between extant, reconstructed, and hypothesized become very difficult to see. The combination of these conditions means that the dataset is paradoxically both sprawling and sparse, and very difficult to untangle. It is necessary to make use (with a critical eye) of some very old measurements and analyses. Sometimes, it is possible to supplement or amend these with the results of modern systematic surveys, but as we shall see below, the results published by these surveys are often (though not always) no more complete than the earlier reports, and sometimes require a similarly critical approach.
This task is very difficult to do at all, let alone concisely. In the interest of clarity, this section will be organized spatially. After a brief overview of the sorts of structures that will be considered, I will discuss the apses on the south side of the western slope, then the apses of the west side of the south slope, continuing in a counterclockwise fashion until the apses of the northeastern corner. The perimeter structures of the northern slope and the western slope are mostly unexcavated and have never been published, so they are omitted. For each section of the perimeter, I will summarize the existing data for the dimensions, construction, and dating of the structures therein.
The perimeter of the Byrsa complex was essentially comprised of façade walls, staircases, rectangular rooms, and apses that lined the complex's edges along the cardo IV east, decumanus I south, and cardo maximus. A brief overview of the apses is warranted. These were rectangular rooms that were separated by rectilinear walls, and that each had an opening onto the street and, opposite that opening, a semicircular recess topped with a semi-dome (cul-de-four).
112
The term “apse” technically refers only to a semicircular recess (Curl 2006), but many archaeologists at Carthage seem to have extended it to also include the room to which the recess is attached. For a discussion on this usage in the context of the French Mission, see Gros (in Byrsa III, 7 n. 3).
While these apses may have performed various functions during their lifetime,
113
Ladjimi-Sebaï (2005, 90) follows Gros and Deneauve (1980, 324) in suggesting that the southwestern apses functioned as small shops, but this assignment seems purely speculative. The function of the eastern apses is also uncertain, but it seems that the apse on the axis of the decumanus maximus was at one point designed to house a statue (Ladjimi-Sebaï 2005, 288-289; Byrsa III, 29). Gros (in Byrsa III, 36-37) suggests that it may also have stored books.
this thesis is concerned only with their structural purpose. They served as the support system of the outermost retaining wall for the Augustan embankment, a role that was essential from the very beginning of the complex’s construction.

5.1.3.1 The Southwest Perimeter

The Roman features of the southwestern section of the perimeter are primarily described in the 1974-1975 site report of Deneauve and Villedieu (Byrsa I, 143-182), and some subsequent findings are published in Gros and Deneauve (1980). These researchers identified a series of five apses (hereafter “Series 1”) along the southern part of the western side, of which remains of three are extant. The other apses were either destroyed by prior excavations or incorporated into a later set of substructures (walls N, S, and O; see section 5.1.1).
114
These apses were first encountered in the late 1880s by Delattre, who thought they were Roman cisterns (not discussed in publication, but marked on his map in Delattre 1893a, pl. XI). Subsequent excavations in this area by Lapeyre (around 1934) cleared the apses below the foundation level, causing the first one north of the SW corner to collapse (Byrsa I, 167). The first architectural survey of these apses was conducted in 1974-5 as part of the UNESCO-backed excavations. By this time, most of the structures were destroyed, and it was no longer possible to date the remains through stratigraphy.
The extant, reconstructed, and hypothesized figures in Series 1 are summarized in Figure 5.18.
image: img/fig/28C__ures_Sitemap_Phase1_FocusSeries1_WithLabels.png
Figure 5.18: Summary map of Series 1 (in the southwest perimeter) during Phase 1. CRS is Carthage / Nord Tunisie (EPSG:22391). Arrow indicates True North.
The rectilinear walls rested on a foundation composed of two courses of rectangular stones (Byrsa I, 168).
115
The only extant example is the northern wall of the first apse north of the corner. Only one block of the second course remains (Byrsa I, 168).
The types (sandstone or limestone, or a combination thereof) and dimensions of these stones have not been published, but rough measurements taken from map suggest lengths around 1.5 m and widths around 1.0 m. The semicircular walls rested on the tufa bedrock of the hill (Byrsa I, 168).
The rectilinear walls themselves have survived just barely, if at all, but judging from Beulé and Delattre's descriptions of the southern apses (apparently confirmed by Deneauve's excavations—see Gros and Deneauve 1980, 322), they would have been constructed in large-block opus quadratum.
116
Deneauve and Villedieu (in Byrsa I, 168) describe a series of blocks that serve as a foundation for some sort of jamb in one of the rectilinear walls. but it is unclear if the researchers are consider the blocks a foundation proper, or else part of the rectilinear wall above them. I assume it is the latter, since the rectilinear walls of the south slope are described as predominantly opus quadratum resting on rudus foundations (see e.g., Gros and Deneauve 1980, 322).
The semicircular walls were composed of small pieces of stone rubble bound together with lime and lined with opus reticulatum (Byrsa I, 167). As with the foundations, the types and dimensions of these stones have not been published, but map suggests a rubble layer thickness around 0.9 – 1.0 m and a reticulatum layer thickness of about 0.15-0.20 m.
The ceilings of these apses have not survived—they were very likely destroyed during the construction of substructural walls O, N, and S. Deneauve and Villedieu report a large fragment of a vault in opus caementicium inside the southernmost apse, but it is unclear if this came from the apse itself or from some other structure (Byrsa I, 168).
These apses likely had a façade wall, as indicated by the shape of the surviving rectilinear wall foundations, but none of this wall appears to have survived (Byrsa I, 168). Its construction may have been identical to that of the rectilinear wall that abutted the north side of the northernmost apse, perhaps comprising the façade from that point northward (Byrsa I, 168).
117
Gros and Deneauve (1980, 323) suggest an alternate interpretation, for which I have found no material evidence: this wall may instead have been part of a series of rectangular rooms, which have not survived.
As Gros and Deneauve reconstruct them (), the apses had very similar dimensions. Interior diameter varied between 3.7 m and 3.9 m. Interior length varied between 6.4 and 6.3 m, Rectilinear walls were about 0.6-0.7 m thick. Semicircular walls were about 1.1 m thick. The façade walls fronting each rectilinear wall were assumed to all be the same size, based on the only extant one (): 0.97 m wide and 1.52 m long. On the basis of construction, Deneauve and Villedieu date the apses of Series 1 to Phase 1.
To the south of Series 1, Deneauve and Villedieu found the remains of a rectangular corner room constructed of façade walls is opus quadratum and opus reticulatum (Byrsa I, 164-167). The room measures approximately 8.9 m in length, and its width is about 5.8 m at its west side and 5.5 m at its east side). Based on its construction, this room likely dates to Phase 1, although later alterations (including the installation of some cisterns) have made its original function unclear.
118
For the chronology of this room, see Gros and Deneauve (1980, 329).
This room is also shown in Figure 5.18.
To the east of that corner room, researchers identified a series of at least six apses (of which remains of three are extant) along the western part of the southern side (hereafter “Series 2”).
119
It is possible that parts of the rudus of one or two other apses are extant, but these pieces cannot be identified on Gros and Deneauve's map ().
The extant, reconstructed, and hypothesized features from Series 2 are summarized in Figure 5.19. In construction, these apses mostly mimic the previous

alignment: the semicircular walls were lined with opus reticulatum (which presumably served as facing for a matrix of rubble joined with lime), the rectilinear walls were build in opus quadratum with stones from the Punic destruction layer, and there was a façade wall (opus quadratum or perhaps opus reticulatum) (Gros and Deneauve 1980, 322).
120
Gros and Deneauve (1980, 322) do not describe the construction of the semicircular walls beyond noting that they include opus reticulatum. Judging from map , it seems likely that the reticulatum facing was attached to the same materials as for the previous alignment, namely stone rubble joined with lime. For the rectilinear walls, Gros and Deneauve (1980, 322) note that only two stones from a single wall are preserved; these cannot be identified on map .
Gros and Deneauve reconstruct façade walls between 0.70 and 0.75 m thick, rectilinear walls about 0.60 m thick, and semicircular walls about 1.0 m thick (). Contrary to the previous alignment, the apses’ rectilinear walls rested on rudus foundations, their interior diameters varied between 3.30 and 3.70 m, and their interior lengths varied between 5.9 and 6.2 m (Gros and Deneauve 1980, 322). On the basis of construction, Gros and Deneauve date the apses of Series 2 to Phase 1.
Gros and Deneauve's map () reconstructs an additional two apses to the east Series 2, which basically keep Series 2's dimensions and construction. After those two apses there is about 10 m of no recorded remains before the alignment of apses resumes with the next series. The area containing the two reconstructed apses, the gap, the next series, and several more apses to the east was excavated in the early 1890s by Delattre. While his measurements and map (1893a, pl. XI; also called ) are not precise or accurate enough to be trusted, I will briefly summarize his descriptions. Delattre claimed to have identified eight extant apses.
121
Delattre (1893a, 102) says that his trenches covered 8 extant apses (though only 7 are shown in his map) in a non-continuous series, leaving two gaps. The gap to the east corresponded with a section of the embankment that Delattre left unexcavated which probably contained most of the Series 3 apses discussed below; it was approximately 4 apses wide. The gap to the west, which was approximately 3 apses wide, was excavated by Delattre. The absence of the 3 apses here was likely caused by later modifications that destroyed the intervening apses. There may have been a 9th apse that he excavated next to the westernmost one on his map—he briefly mentioned it one time previously (1891, 52) but never again (Byrsa I, 48 n. 47). Thus, he claims to have found an alignment of 15 apses.
By the time of his excavation, the rectilinear walls of these apses were entirely gone—perhaps taken as spolia by people living nearby, who would have noticed the apses that Beulé uncovered previously (see Section 5.1.3.2)—leaving behind only the semicircular recesses, which Delattre says were constructed of some sort of stone masonry (1893a, 102-103).
122
The specific term Delattre uses here is “moellons,” which can refer to many different kinds of stonework.
At least one of the apses was lined along its interior with opus reticulatum (Delattre 1893a, 102).
123
Delattre's map can be roughly georeferenced relative to walls S, N, and Es. In the georeferenced map, feature VI (which seems to be one of the pieces of Delattre's alignment of apses) overlaps very well with . Consequently, it is reasonable to suggest that this is the apse wall lined in opus reticulatum that Delattre describes.
Delattre’s (1893a, 102) measurements of these apses suggests an apse width (interior diamter + widths of the side walls) of 3.20 m, which is rather less than that of Series 2. This figure is very imprecise because it is an average of Delattre's hypothesized original number of apses over the approximate length of Delattre's excavations (Byrsa I, 48 n. 48). I retain the reconstruction of the two apses from , and then hypothesize three other apses whose dimensions match those of the westernmost apse in Series 3.

5.1.3.2 The South Perimeter

Such variability grew more pronounced about 8 m farther east, where the UNESCO-backed excavations uncovered a series of about five apses (hereafter “Series 3”) that were originally continuous with those of Series 2.
124
There are 4 fully preserved apses (i.e., including the entire semicircular recess and remains the full width of the semicircular walls) shown on the maps of the Byrsa volumes (, , , , ), but six fully preserved apses are shown on and in Morel (2011b, fig. 1). It seems that these latter two maps may have conflated the gaps from the destruction of the rectilinear walls with the gaps from the destruction of the stone-block sections of the semicircular walls. The apses are also show in Morel (2011a, 327 fig. 1), this time in the correct quantity.
The extant, reconstructed, and
image: img/fig/30C__ures_Sitemap_Phase1_FocusSeries3_WithLabels.png
Figure 5.20: Summary map of Series 3 (in the south perimeter) during Phase 1. CRS is Carthage / Nord Tunisie (EPSG:22391). Arrow indicates True North.
hypothesized features from Series 3 are summarized in Figure 5.20. They are likely the apses that were left buried by Delattre's excavations, but which are still shown in dotted lines on his map (1893a, pl. XI). As far as I am aware, the only published descriptions of these apses are from Lancel (in Byrsa I, 48), who notes very briefly that they are constructed from small pieces of rubble (I assume joined with lime) inset with large stone pillars in opus quadratum, and Morel (2011a, 352), who mentions (also very briefly) that the semicircular walls are in opus caementicium with numerous ceramic and stone inclusions that appear to be Roman in origin, suggesting a later construction date.
125
Lancel’s exact description (Byrsa I, 48): “quelques vestiges des autres absides subsistent encore (fig. 3), ils présentent un appareil de petits moellons dans lequel étaient intercalées des jambes de pierre de grand appareil. Les blocs ont été arrachés mais leur empreinte reste bien visible.” Morel's exact description (2011a, 352): “en revanche, dans le secteur B, ce mur, désormais dépouillé de son revêtement et dont beaucoup des blocs de grand appareil qui en constituaient l’armature ont été récupérés par la suite (sans doute à l’époque arabe), incorpore dans son opus caementicium de nombreux vestiges manifestement romains – pyramidettes d’opus reticulatum précisément, fragments de tuiles, morceaux de marbre (dont certains moulurés) – qui donnent à penser que cette section du mur n’a pas été édifiée entièrement, il s’en faut, dès les tout premiers temps de la Carthage romaine.” On Morel's map (2011a, 327 fig. 1), dotted lines in between the apses seem to indicate that the rectilinear walls narrowed when they were no longer set into the semicircular walls. I do not retain this hypothesis.
Because I have not found any confirmation of Morel's cursory assessment, I retain the late 1st-century BC construction date accepted by Lancel, Gros, Deneauve, and Ladjimi-Sebaï. The semicircular walls can be seen on map , along with a few remaining sections of rectilinear walls in opus quadratum that were set deep into the rubble-lime matrix, all other stone blocks having been removed by previous excavators or local people.
Among the four apses whose recesses were completely preserved, interior diameter was between 2.2 and 3.5 m. If we assume that the outer and inner edges of the façade were colinear with those of Series 2 (meaning that the façade walls for Series 3 were 0.75 m thick), then interior length varied between 5.3 and 5.9 m. The rectilinear wall thickness varied between 1.0 and 1.5 m, and the semicircular walls are preserved to a thickness ranging from 1.6 to 2.2 m, with stone pillars 1.0-1.2 m wide and 0.9-1.7 m long. I hypothesize that for each apse, the façade wall segments had lengths that provided an opening proportional to that reconstructed for the apses of Series 2.
The mode of construction for Series 3 was markedly different from that of Series 2. The rectilinear walls were much thicker and set deeply into the rubble-lime matrix of the semicircular walls. These semicircular walls were also much thicker and were reinforced by thick stone insets, and they tended to be “flatter,” that is, the central angle of the arc of their intrados is smaller. The transition between these two modes of construction can be observed in the westernmost apse of Series 3, whose semicircular wall does not have a stone inset, and whose eastern rectilinear wall does not appear to be set into the rubble.
126
The second observation could be caused by a trick of perspective in the published map, so further confirmation is wanted. Such confirmation may be partially supplied by Delattre's map (1893a, pl. XI), which appears to show the very transition I note here; apses on the west side of the gap of 4 appear not to have blocks inset into the semicircular walls, while apses to the east of the gap do.
The extrados of the Series 3 apses appear to be contiguous with a thick Roman retaining wall (), partially destroyed by prior excavations and spoliation, whose northern extent was found by the UNESCO-backed excavations to the south and southwest of Punic block B (Byrsa II, 143). While this wall is mentioned several times in the Byrsa volumes, I am not aware of a previously published description of this wall’s construction or dimensions, and its extents are not directly geolocatable.
127
It is very difficult to determine the state of this wall's preservation from the few mentions of it in prior publications. At one point, Lancel seems to say that Beulé’s excavations (and the spoliation that followed) completely destroyed this wall along the southern slope (Byrsa II, 85), but contradicts this assessment later on in the same volume, where he notes that his own excavations encountered the wall just southwest of Punic block B (Byrsa II, 143).
Lancel suggests that the wall was destroyed only within the limits of Beulé’s “Fouilles G,” meaning that the extant limits of the former allow the limits of the latter to be precisely identified (Byrsa I, 14).
128
Curiously, Beulé (1861) does not seem to mention this wall at all, even though it was almost certainly behind the apses he excavated in his “Fouilles G.” This point will discussed further below.
Unfortunately, Lancel did not plot the extant limits of the former on any of his maps.
129
Although the northern side of this wall is plotted on many maps (e.g., , , ), none of them distinguish extant segments from reconstructed segments.
I will assume that the limits of the extant section of the wall are even with the limits of Series 3. To the east and west of these apses, the limits of the rest of the retaining wall thus be hypothesized. I hypothesize that the eastward limit was dictated by the wall of amphorae found by Beulé (1861, 39) and Delattre (1894, 89-91), and that the western limit was imposed by the extrados of Series 1. This is consistent with the hypothetical(?) extents shown on maps and .
Based on my above assumption, Beulé's “Fouilles G” began at the western limits of Series 3.
130
It is possible that this assumption conflicts with Delattre (1893a), whose map indicates 2 excavated apses between the gap of four and Beulé's “Fouilles G.” If That gap of four really does correspond with the four fully preserved apses of Series 3, and if Delattre meant that Beulé's excavations began at the eastern edge of those 2 apses, then they would begin one apse to the east Series 3, rather than zero as I have assumed. Ultimately, there is not enough information to resolve this delimma, so I will follow my initial assumption.
These excavations stretched for about 40 m to the east and unearthed another series of (likely) six apses (hereafter “Series 4”).
131
For the length of the excavations, see Beulé (1861, 46, 59, 79). The number of apses warrants some qualification. On Beulé’s map (1861, pl. I; reproduced in ), 6 apses are shown, but he does not specify their quantity in his description. Delattre (1893a, 102), excavating 30 years later, retains the number 6. Beulé’s map shows these apses in an alignment that extends slightly past the axis of the eastern apses, but this positioning is certainly a cartographic error. Deneauve (in Byrsa I, 48; see also map ) suggests that these apses were in fact a little to the west of the SE corner of the complex, and that the apses in the actual corner were only observed by Delattre in 1893. Delattre’s (1894) description does appear—very obliquely—to agree with this assignment, but does not include a map to confirm it.
The extant, reconstructed, and hypothesized features in Series 4 are summarized in Figure 5.21. Beulé describes their construction thus: the apses had an interior diameter of 3.30 m, an internal length (from the apex of the recess to the inside of the fronting wall) of 4.20 m, a rectilinear wall

thickness of 1.10 m, and a fronting wall thickness of 1.00 m. Five apses were constructed (both rectilinear and semicircular walls) from large stone blocks measuring as big as 1.50 x 1.25 x 1.00 m (Beulé 1861, 60). For the rectilinear walls, these appear to have been laid in the regular, interlocking courses of opus quadratum (Beulé 1861, 60).
132
Though Beulé does not specifically say opus quadratum, it seems proper based on his illustrations (1861, pl. II fig. 2).
For some courses, perhaps specifically those of the semicircular walls and/or the foundations, the blocks were not regularly shaped, but still fit very closely together (Beulé 1861, 61 and pl. II fig. 2).
133
Beulé’s description here is ambiguous: “quoique les assises paraissent, au premier aspect, réglées, elles ont cependant des saillies et des retraites, des tenons et des mortaises , qu'on dirait empruntés à l'agencement des charpentes” (1861, 61). “Assises” could refer generally to some of the stone courses, or it could refer specifically to the foundations of the walls. In Beulé’s illustration (1861, pl. II fig. 2) of one of these apses, it appears that the rectilinear wall is opus quadratum, while the semicircular walls are in irregular stonework. Gros and Deneauve (1980, 323) identify this irregular stonework as “une sorte d'opus africanum intercalant des jambes de pierre dans un opus incertum.”
Mortar was found in some external joints and on some uppermost courses, but nowhere else (Beulé 1861, 63). The sixth apse was constructed mostly in opus reticulatum (Beulé notes this is one of several, the rest being presumably unexcavated), and at the time of excavation it still stood 8 m high (Beulé 1861, 63).
134
Beulé’s description is ambiguous. In his initial assessment, it seems that he is referring to a “cintre” (arch) in opus reticulatum, rather than an apse, but in a later elaboration he refers to it as a cul-de-four, which properly is a term for semi-dome but is also commonly used to refer to the vault formed beneath a semi-dome (Curl 2006). Deneauve (in Byrsa I, 48) seems to think that Beulé was describing an apse—i.e., both the rectangular room and the recess (see n. 112)—but I think it is more likely that he was describing only the recess, that is, the vault beneath the semi-dome, and I retain this assumption going forward.
Six meters above the floor, the walls of the recess
135
Here, Beulé uses the term cul-de-four to mean the vault below the semi-dome.
were pierced with square holes which Beulé (1861, 64) surmised once held cross-beams. Beulé does not say whether the other apses also had these holes, but he does note that none of them survived to a height greater than 5 m (1861, 64).
Some aspects of Beulé's description warrant further scrutiny. Judging from the variability observed in the dimensions of the Series 3 apses, Beulé very likely homogenized his measurements to make the apses all appear the same size.
136
Or he may have only measured sections of each apse, and then combined the measurements together. His map (1861, pl. I) shows some sections of the apses in dark shading, and other sections in light shading. These differences in shading may have been intended to distinguish excavated sections from unexcavated sections. Ultimately, it is impossible to tell one way or another. His description of the apses includes no mention of the different shading, and his schematic drawing of the apses (1861, pl. II fig. 1) shows patterns of shading that are different from the patterns in his map (some dark shaded sections appear to have grown larger, while others appear to have shrunk). Subsequent reproductions of this map (e.g., Byrsa I, 15 fig. 1; Ennabli 2020, 77 fig. 32) seem to have basically homogenized the shading.
Nevertheless, his measurements are the only ones we have from this point onward, until the apses of the eastern basilica: all of the apses in Series 4, all of the apses between Series 4 and the southeast corner of the complex, and all of the apses between that corner and the basilica have been destroyed or incorporated into modern constructions, and no measurements or maps of them were ever published. Consequently, I retain Beulé's measurements for Series 4, and I will assume that they are applicable to all of the apses after Series 4 as well. All of these apses will be considered hypothesized.
The dimensions and construction that Beulé reports for Series 4 are noticeably different from those of Series 3 (Figure 5.21). Aside from a slight widening in the rectilinear and façade walls, Beulé's apses are significantly shorter, with an interior length of just 4.2 compared to the 5.7-6.0 m of the eastern apses of Series 3. This means that their extrados would (just barely) not touch the intrados of the nearest apses of Series 3. Moreover, Beulé makes no mention of the south slope retaining wall that was observed to be contiguous to the extrados of Series 3, even though he had to have encountered it, since its presence in this area is attested in the negative (Byrsa II, 85 n. 2).
137
Lancel maintains that the retaining wall passed through this area, even though his excavations found no positive remains of it—see n. 127.
I propose that these discrepancies may be caused by two simple problems: first, that the two easternmost apses of Series 3 were originally lined with semicircular opus quadratum walls that have long since disappeared due to spoliation; second, that Beulé's description of his apses' semicircular walls may reflect the dimensions of similar interior stone walls which lined larger, approximately flat (though perhaps very mildly curved) walls constructed of rubble joined with lime. These semicircular walls would then have been contiguous with the retaining wall. Framed this way, Beulé's odd dimensions and his omission of the retaining wall fit together with his obvious shortcomings. His preconceptions, nurtured by his classical training, inclined him to fixate on the most immediately impressive features of what he thought were the Punic ramparts, and to utterly destroy anything less impressive that proved to be an obstruction.
138
At one point in Beulé's excavations of this area, progress was halted by the presence of large sections of walls built in mortar and small stones, which Beulé thought dated to the time of Theodosius, and which were “à peu de profondeur, renversées par pans énormes, couchées en terre dans toute leur longuer” (Beulé 1861, 50). I have to wonder if these sections of wall may not have been part of the upper section of the retaining wall. Ultimately, the question is moot. When neither Beulé's workers nor Beulé himself could break through the walls, he destroyed them with explosives (Beulé 1861, 50).
Contrary to what appears on his map, it is certain that he did not clear all six apses down to the level of their bases; by his own admission (1861, 59), temporal and financial constraints forced him to simply follow the walls with discrete trenches. This strongly suggests that he would have disregarded adjacent walls of much rougher rubble-and-mortar construction, since the features that captivated him were almost entirely constructed in large-block opus quadratum.
Consequently, I hypothesize that the apses excavated by Beulé were actually constructed with a 2.0-1.5 m thick rubble-and-mortar wall lined with a 1 m semicircular fronting wall of opus quadratum, and with rectilinear walls extending past the intrados of the fronting wall to meet the southern edge of the rubble and mortar wall. I retain this hypothesis for all of Series 4 and the rest of the apses between it and the start of the amphorae wall.

5.1.3.3 The Southeast Perimeter

Several decades after Beulé, Delattre (1893b; 1894) excavated an unspecified number of apses to the east of Series 4, whose contiguity therewith is unknown.
139
Delattre’s (1894, 89-90) brief description of these apses is very opaque—see n. 131.
These features are summarized in Figure 5.22. He notes that one of these apses had interior facing in opus reticulatum (1894, 89-90); the rest presumably were lined with large-block stonemasonry, as was the case for Series 4.
140
Beulé's vague descriptions of the stonemasonry were clarified by Gros and Deneauve—see n. 133.
Leaning against the extrados of these apses, Delattre found a very large wall of stacked amphorae (), which had been filled with the earth of the Augustan embankment and then arranged in an interlocking pattern that was about 4.40 m thick and 6.00 m high (1894, 89-91). This wall stretched for 50 m around the bend of the southeast corner of the complex, with its western end located close to the eastern end of Series 4 (1894, 89). While Delattre provides no map of this area, the extents of this amphora wall can still be reconstructed with some degree of certainty, provided that we make some assumptions about the layout of this sector.
At the southeastern corner of the complex,
141
I have reconstructed the location of this corner at the point where the line of the reconstructed façade of the southern apses in ( in Appendix C) intersects with the line of the eastern façade of the basilica in ( in Appendix C).
the perimeter turned approximately 90 degrees to the north. There were probably apses along the perimeter here—this is strongly implied by Delattre's (1894) description and it is retained in —and I assume that they were of dimensions identical to those of Series 4. About 34 m north of the corner, Deneauve's Phase 1 reconstruction () has a gap in the perimeter to allow for a large staircase (; approximately 30.2 m long and 10.4 m wide) that connected the top of the platform to the cardo IV east below.
142
I have classified this staircase as hypothesized because I could not find any direct evidence for it in prior publications. For other mentions or discussions of staircases here and elsewhere on the Byrsa perimeter, see Byrsa I, 42 n. 5; Gros 1982, 645; Deneauve 1990, 153 n. 10; Ladjimi-Sebaï 2005, 73.
His Phase 1 reconstruction has the eastern end of this staircase flanked by two pairs of apses (which terminate their segments of the perimeter), and the western end of the staircase founded on a short substructural wall.
143
These are (built Phase 1) and (built Phase 2). For a brief overview of these walls, see Section 5.1.1.7. Deneauve seems to have been somewhat mistaken used on the locations and dimensions of these walls. His Phase 1 reconstruction () shows the staircase ending in a wall that is as long as , but located on top of . Likewise, his Phase 2 reconstruction () shows the staircase ending in a wall that is as long as , but located on top of . This is the opposite of what is shown in and
Deneauve's reconstruction calls for the dimensions of the staircase to change between Phase 1, and Phase 2, but due to a lack of evidence and some key inconsistencies, I do not retain this.
144
In Deneauve's Phase 2 reconstruction, this staircase's width decreases by the width of wall F, and the northern pair of flanking apses is shifted south accordingly. This arrangement seems purely hypothetical to me, and I do not retain it. I have found no evidence at all that wall F continued past ; such is not shown in , nor . Note that Deneauve conflates the placement of and —see n. 143.
At each corner formed by the 90 degree turns in this section of the perimeter, Deneauve (, ) assumes there was a corner room analogous to the rooms that definitely existed in the southwest and northeast corners of the complex. I retain this assumption, and in hypothesizing the layout of these rooms I assume that their outer walls were colinear with the façade walls of the neighboring apses, and their inner walls were simply the rectilinear walls of the neighboring apses. I further assume that their widths and lengths were not less than the interior lengths of the neighboring apses, i.e., 4.2 m.
Finally, I assume that the flanking apses terminated the substructural walls ( to the south, to the north) that abutted them. This is contrary to Deneauve's reconstructions (, ), but I do not see any reason to accept his suggestion that walls D and G cut off the openings of the flanking apses here.
145
Or, if they didn't cut off the openings, that they formed the façade; the rough construction of walls D and G would not have been suitable for this purpose. It is completely unclear which of these two options Deneauve meant to convey, because his very rough illustrations do not follow any reliable symbology, and because he does not discuss them in enough depth in the text.
Given these assumptions and hypotheses, and based on the dimensions reported by Delattre, the extents of the amphora wall can be posited with a reasonable degree of confidence. This is shown in Figure 5.22, where I have extended the amphora wall to an interior length of 50 m. It is notable that the amphora wall seems to replace both the retaining wall and the rubble-and-mortar wall reconstructed and hypothesized for Series 4. Delattre clearly says that the amphorae leaned against the extrados of the apses, and based on my interpretation of Beulé's description, I can only assume that Delattre means the inner semicircular walls that by this point were likely constructed almost exclusively in large-block stonemasonry. Why (and how) could the thick substructural walls for Series 3 and 4 have been replaced with a wall of amphorae in this area, which constituted by far the steepest section of the perimeter?
146
The height of the perimeter above the street was at least 19 m, if Beulé's (1861, 42) measurement is to be trusted. It seems to be retained by Lancel (e.g., in Byrsa I, 14) and Ladjimi-Sebaï (2005, 39), so I retain it, too.
I propose that these substructural walls were not necessary in this sector because the descent of the staircase lessened the pressure from the embankment, allowing the south façade of the staircase and the southernmost apses in the eastern perimeter to take some of the load. Indeed, the western edge of the amphora wall is almost completely even with the western end of the staircase—this does not confirm my hypothesis, but it is consistent with it.
One last topic must be discussed before I leave behind the apses of the southern perimeter: dating. It is almost universally agreed that the apses along the southwest, south, and probably southeast slopes date to the Augustan foundation. This dating is based primarily on their construction and partially on their context. The use of opus reticulatum and opus quadratum composed of stones taken from previous Punic structures is commonly found in other Roman structures which date to the colony’s first few decades. Along the southeastern slope, the wall of amphorae could be narrowly dated to between 43 and 15 BC on the basis of stamps (Delattre 1894, 91).
147
Delattre's initial date was recently confirmed by Freed and Moore (1996) and remains universally accepted.
While this logic may not seem watertight—comparative architectural dating is rather imprecise, and the amphora wall did not stretch across the entire south slope—the destruction of the southern apses and the lack of documentation for their stratigraphic context ensures that no other material evidence will be forthcoming. Nevertheless, to these factors might be added one more, namely, that the prospect of modifying sections of this massive southern support, which for most of its length had to withstand the outward pressure from the embankment over a height greater than 10 m, was very probably unattractive. It seems likely that in this sector of the complex, more than any other, structural modification of the retaining wall risked shifting the soil of the embankment and destabilizing the structures above.

5.1.3.4 The East Perimeter

The extant, reconstructed, and hypothesized features of the east perimeter are summarized in Figure 5.23. Based on Deneauve's reconstructions (, ) the pair of flanking apses north of staircase and an adjacent corner room resumed the complex's perimeter, which stretched another 50 m to the north before turning westward again to accommodate a second staircase (), which again was flanked with two pairs of apses.
148
As with the previous staircase, I have been unable to find any published evidence for this one. I also have been unable to find evidence for the southern pair of flanking apses. Consequently, I consider these features to be hypothesized. Deneauve's reconstructions (, ) call for this staircase to change widths between Phase 1 and 2, based on his assumption that wall F' extended all the way to the perimeter. As with the previous staircase (see n.142), I have found no evidence at all to support this assumption, so I reject it.
Since the topography of this stretch of the perimeter would probably have been comparable to that around Series 4, it is reasonable to hypothesize that these apses had roughly the same dimensions as Series 4, and were similarly backed by a rubble-and-mortar wall followed by a secondary retaining wall. Following Deneauve's reconstruction, I assume that there was a corner room at this northern turn, and for both rooms' dimensions I follow the same assumptions that I made for the southeast perimeter. This section

of the east perimeter was in Beulé's time occupied by an old French cemetery and now is completely buried under modern constructions, so it has never been formally excavated.
On the north side of this staircase lie the remains of the last documented section of the complex's perimeter, where Beulé (1861, 67-74) found an alignment of five apses (of which he excavated two) on the eastern slope of the hill, beginning a little over 100 m north of the complex’s southeast corner to avoid the old French cemetery. His sparse description of their construction is superseded by the modern survey conducted by Pierre Gros as part of the UNESCO-backed excavations.
149
Notably, Gros (in Byrsa III) presents his results thematically, rather than organizing them by field survey, as was done the previous Byrsa volumes. As Gros himself acknowledges (Byrsa III, 3), while this makes it much easier to understand and visualize the development of the structures that he investigates, it tends to blur the distinction between observation and analysis, making it harder to critique or reproduce his conclusions. This organization is reflective of Gros’s broader investigative approach, which proceeded according to “le principe de la cohérence et de la repartition symétrique des structures” (Byrsa III, 25).
The extant, reconstructed, and hypothesized features of the northeast perimeter are summarized in Figure 5.23
Gros identified nine apses in Beulé’s alignment (four on either side of a central apse that was on the axis of the decumanus maximus), and two additional pairs of apses oriented perpendicularly, bordering the alignment to the north and south.
150
Lapeyre seems to have seen, or at least assumed, the perpendicular apses, but never published on them (Byrsa III, 7 n. 5). Gros (1982, 637-640 n. 5) says that while they appear “sur certains plans anciens,” it is impossible to tell whether they were actually seen or just hypothesized.
Originally, according to Gros, the apses appear to have been basically homogenous in construction, although they were decorated differently and some were modified in later periods.
151
Regarding decoration, cf. the cul-de-four of the central apse, with its caissons, and its neighbors, which have none (Byrsa III, 9). Regarding modification, see e.g. the apse immediately south of the central apse, which had large horizontal “indentations” cut into its semicircular wall (Byrsa III, 9).
Focusing most of his attention on the central apse, due to its superior preservation, he described their construction as follows.
152
I must point out that one of the great shortcomings of Byrsa III is its complete lack of a systematic architectural inventory for the retaining wall and associated support structures. The partial inventory that is given (Byrsa III, 72-105) is limited to decorative and structural materials from the basilica and its façade; finds from the apses and other substructures are absent. This absence, while not unexpected (given Gros’ overall approach—see n. 149), made it much more difficult to determine and critique the reconstruction of some features, since such details as block dimensions and the components of composite materials (e.g., opus caementicium) are very often omitted. Additionally, some features, such as the N-S retaining wall running tangent to the eastern apses, are only cursorily mentioned when their presence is pertinent to the current analytical theme, and are not marked on any of the maps, leaving the reader largely in the dark as to their dimensions, construction, and dating.

Figure 5.24: Summary map of the northeast perimeter during Phase 2. The dating of to Phase 1 is very hypothetical. CRS is Carthage / Nord Tunisie (EPSG:22391). Arrow indicates True North.
The rectilinear walls rested on earthen berm (“banquette”) foundations—presumably cut into the elevation of the hill as it climbed to the north—while the paved interior of the rectangular rooms had more complex foundations composed of a layer of pebble-cement on top of a layer of rubble.
153
The only rectilinear wall foundation examined by Gros is the wall of the apse immediately north of the central apse—presumably the southern wall, although Gros does not specify (Byrsa III, 33). The foundation of the interior paving is only examined (and perhaps only extant?) in the central apse (Byrsa III, 29). Gros seems to say at one point (Byrsa III, 34) that there were also some foundations in blocks of Hamilcar sandstone, but he does not specify where. The central apse seems to have blocks only from El Haouaria (Byrsa III, 7), while the apse immediately to the north has blocks from both El Haouaria and Hamilcar (Byrsa III, 33).
The foundation of the semicircular walls does not seem to have been directly investigated, probably to minimize the risk of collapse, but it is reasonable to assume that it was identical to that of the rectilinear walls.
The walls themselves were of bipartite construction. The bottom section was El Haouaria and Hamilcar sandstone in opus quadratum, with block width usually 0.40-0.50 m, height 0.50-0.90 m (shorter for higher courses), and length around 0.50-1.2 m.
154
The central apse seems to have blocks only from El Haouaria (Byrsa III, 7), while the apse immediately to the north has blocks from both El Haouaria and Hamilcar (Byrsa III, 33). Block height is reported by Gros only for the blocks of the central apse. Block lengths are not directly reported but can be roughly determined from map B3.P.64a. Block width can be estimated by halving the width Gros gives for the rectilinear walls, and this estimate is confirmed by measuring blocks in .
The blocks had 2.5-5 cm thick joints of beige mortar, and they all bore marks from lifting clamps (Byrsa III, 7). There were five courses for the rectilinear walls and six courses for the semicircular walls. On top of the opus quadratum there were three courses of stones shaped to look like bricks (specifically bipedales), some of limestone and others of sandstone, which were also used in the facing of a bench-like feature in the central apse (Byrsa III, 34). They were presumably joined with the same mortar as was used in the opus quadratum. Gros did not report their dimensions, but Beulé puts the combined thickness of the three courses at 0.40 m (1861, 69). It is not immediately clear if the brick-like stones extended over the rectilinear walls, but Gros (Byrsa III, 7) seems to imply that they do. The impost was pierced with a series of rectangular holes that Gros suggests held scaffolding used during the construction of the cul-de-four over the recess (Byrsa III, 8).
The layer of brick-like stones served as an impost for the vaulted ceiling of each apse, which was constructed in opus caementicium (Byrsa III, 7-8). Over the semicircular recess, this was a cul-de-four, and over the rectangular room it was a barrel vault. The first northern apse may have had a different ceiling system, but it is not clear if Gros accepts this (Byrsa III, 10-11).
The apses were partially enclosed by a fronting wall composed of stonework, presumably in opus quadratum like the rectilinear walls. It was joined to them with the same mortar, had a width of around 1 m, and may have extended for about 1.6 m on either side of each rectilinear wall, creating openings of about 2.75 m for each apse (Byrsa III, 33).
155
The reconstruction of the openings is very tenuous, since by the time of Gros’ excavations the fronting wall was almost entirely destroyed down to the foundations. The reconstruction hinges on connecting the only remaining above-ground piece of an anta (located just south of the mouth of the central apse) with an adjacent block (embedded in the ground along the same alignment), and then hypothesizing a symmetrical structure on the other side of the apse mouth (Byrsa III, 33). In reconstructing the missing segments of façade wall, I assume that each segment is 4.20 m long, stretching about 1.6 m on each side of the rectilinear wall.
Behind the apses, and operating in conjunction with them, was a massive substructural wall. This wall served to support the basilica’s eastern alignment of columns, and its eastern face appears to have braced the extrados of the apses (Byrsa III, 19) and the eastern rectilinear wall of the first northern apse (Byrsa III, 10). The wall was constructed from blocks of sandstone from El Haouaria, presumably in opus quadratum (Byrsa III, 19). The excavators of the French Mission do not directly report any dimensions for this wall, and like its western counterpart it is shown unlabeled on their maps. Judging from map , its width was about 2.0 m. No extant sections of this wall are published on a map, even though they certainly have been found, so it must be entirely reconstructed. The excavators also do not suggest a date of construction.
Gros pointed out that the stonework used in the apse walls closely resembled that of other structures dating to the Antonine period, prompting him to assign a date of construction in the second half of the second century AD.
156
Gros first attempted to date the apses stratigraphically, by excavating below the foundation level at the mouth of the central apse. Unfortunately, later modifications had completely disturbed this area down to the sterile soil layer. It is not immediately clear why Gros did not excavate through the floor of the central apse or one of its neighbors, since the preservation of the original flooring strongly suggested the presence of datable material below. Perhaps he was stopped by restrictions from the local government or personal concern for the structural or aesthetic integrity of the last intact apses in the eastern alignment. Gros’ date of construction is retained by Deneauve (1990) and Rakob (2000), but apparently critiqued by Ladjimi-Sebaï (2005, 75 n. 292)—see discussion below. Gros himself acknowledges that his date wants for more solid confirmation, since “il s’agit d’une hypothèse, que rien de décisif ne saurait fonder; elle s’appuie plutôt sur une convergence de données qui rendent cette identification possible, sinon probable” (Byrsa III, 37).
He suggested that these Antonine-era supports replaced analogous Augustan-era structures, whose dimensions and construction would have been identical to the apses on the southern (Byrsa III, 27, 34) and southwestern (Byrsa III, 34) slopes.
Gros' dating warrants further scrutiny. It is almost universally agreed that the extant apses along the northeastern slope date to the second half of the 2nd century AD. This dating is based entirely on their construction (particularly the distinctive type of opus quadratum and the use of stones to imitate brick-work) since the UNESCO-backed team of excavators did not find any intact stratigraphy that predated them. Consequently, the support system that predated these apses is not materially attested, and while some reconstructions have been proposed, they seem to be entirely speculative. As far as I can tell, the only reconstruction of the eastern Augustan apses to have been published is that of Gros and Deneauve, which appears without explanation or comment in a plan in . The corresponding plan for the Antonine era () is presumably the plan followed by Gros and Deneauve in the construction of their scale model of the Byrsa complex in the 2nd century AD.
157
Gros and Deneauve (1996, 54) note that this model was constructed by C. Redler and J.-L. Terrer of “Espace Graphique” (presumably an architecture firm) based on plans and elevations that were created by architects Gérard Robine and Philippe de Carbonnières, and by archaeologists Deneauve and Gros. Redler, Terrer, Robine, and de Carbonnières are not credited in any other mention of this model that I have found (with the excaption of Ennabli 2020, 92 fig. 44). Such reductivity around authorship and responsibility remains commonplace in archaeological publication, since those who physically collect data in the field (field school students, local laborers, etc.) are very rarely credited by name in the publication of a field report (noted also in Pollock 2010).
This model was featured on the cover of CEDAC 15 and is still housed in the Carthage Museum (Gros 1997, 347 n. 3), but aside from a brief article in a popular news magazine (Gros and Deneauve 1996), it remains unpublished.
158
In Gros and Deneauve (1996), all of the photos are credited “Centre Camille-Jullian, CNRS.” Perhaps the Centre Camille-Jullian houses other materials on the Byrsa as well? See n. 2.
and are really just sketches—the apses are outlined roughly in dotted lines and the level of detail is quite low—but it is clear enough that in the Augustan-era sketch, all of the apses have the same dimensions: an interior diameter of about 3.5 m, and an interior length of about 6.5 m. In other words, it is assumed that all of the eastern apses had the same dimensions as the south and southwestern apses, but with the same façade as the Antonine apses. Hence, Gros and Deneauve assumed that the construction of the 2nd century basilica involved the removal, not just of the Augustan supports, but also of the 7 m-high embankment over an additional 4 to 5 m behind the those supports. They further assumed that the new supports followed a completely different plan from the old ones. I think both of these assumptions have problems.
Problems with these assumptions can be seen in comparison with a similar building project that took place on a much smaller scale in the southwest corner of the complex. The construction of the southwest temple took place with an elevation level difference (platform level – street level) ranging from about 5 to 7 m, along a relatively limited façade (~16 m), in a corner of the platform that probably was not previously occupied by a large structure. The construction proceeded by encasing the existing supports with new foundations and filling the voids with more soil, allowing the embankment front to advance forward. In contrast, the construction of the basilica took place over an elevation difference of at least 7 m, over a façade more than 80 m wide (almost half of the eastern side of the platform), in a part of the complex that was very likely occupied by a major, albeit smaller, structure with another structure immediately west of it.
159
In Deneauve (1990), the first structure is labeled “basilica?”, while the second structure is labeled “arc.” The absence of a site-wide architectural inventory makes it difficult to find the material evidence for these structures in published records.
It seems unlikely that the construction of the Antonine basilica would have pushed the embankment backward, since, if the ground shifted or settled, it would potentially compromise the structural integrity of other foundations nearby.
Moreover, it seems unlikely that the Antonine apses would have followed a different plan from the Augustan ones, since during the construction of the southwest temple they were incorporated into the new foundations, where they continued to play an important structural role. By extension, if the Antonine apses of the eastern slope were replaced by new apses following a different plan, we would expect to see some trace of them in the new foundation structures. We should not assume that all of the Augustan apses were constructed along roughly the same basic plan: the retaining wall of the complex was a massive construction project that required years—potentially well over a decade—of labor. If anything, we should assume a heterogeneous plan that accounted for local variations in topography and availability of building material. It is not unlikely that there were multiple construction workshops operating in tandem on different sections of the retaining wall. The construction methods used along the south slope were clearly not homogeneous, and there probably was not much aesthetic difference, if all of the apses were originally stuccoed.
Accordingly, I hypothesize that the Augustan apses followed the same footprint of their Antonine successors.
160
The question of the layout of the eastern alignment in the Augustan era could be further clarified if the construction date of the retaining wall running tangent to the Antonine apses was known, but as I noted above, this does not seem possible, given the current state of the published data.
I further assume that the substructural wall abutting the extrados of the eastern apses dates to Phase 1. These hypotheses are summarized in Figure 5.25.

The Punic Features

During the initial construction of the Byrsa complex, existing Punic features were either cleared during the leveling of the summit, destroyed to make way for new Roman substructures, or else simply buried under the growing embankment. The architectural features that are most relevant to this thesis are the walls of the five Punic city blocks (A, B, C, D, and E) on the southern slope, since they occupied the most volume and therefore held the most influence over the energetic cost of the reconstruction.
The original goal of this section was to document the digitization of all of the Punic walls, cisterns, tombs, and other features on the Byrsa Hill. Unfortunately, time and size

constraints have made made complete digitization impossible within the scope of this project. As a preliminary effort, I have digitized the walls of the five Punic city blocks on the southern slope, as well as a few cisterns and tombs. The digitized features are summarized in figures 5.26, 5.27, 5.28, and 5.29.
My digitization of these features must be regarded as preliminary. For the walls, I have not recorded the construction methods, as I did with most of the Roman features, and the boundaries of my feature traces only reflect contiguity and source map, not actual context—in other words, the traces of walls are only divided when the map from which they were traced indicates a gap, or when I switch to a new map for tracing.
161
For a few features, it is impossible to reliably trace a feature from a single map. These are indicated in the relevant tables in Appendix C.
This means that the boundaries between walls—and their Feature IDs—could change in the future, as they are refined to better reflect their discrete archaeological contexts. For cisterns and tombs, I have only traced those features that are included in profiles published within the Byrsa volumes (see Chapter 6).
162
As time and resources permit, I intend to digitize additional cisterns and tombs. These will be made available in the updated repository at https://github.com/josephburkhart/Byrsa-Archive-Active (see n. 21).
The locations and dimensions of these features are given in maps and tables in Appendix C, but some additional observations are worth noting. For block A, all features have been traced from map . Even though this map is more schematic and much less well aligned than most others, it is the only one to show block A, whose walls, almost completely buried under the foundations of a later structure, are shown only on . For block B, all features have been traced from map . While the coverage of this block is not as limited as that of A—it is also shown on maps , , , , , and —all of these either are poorly aligned (), lack detail (, ), or else offer only very partial coverage (, , ). Block C was mostly covered by maps , , and , but these maps were in many places poorly aligned with one another. The alignment was particularly off for , reaching close to 30 cm in some places, which was surprising because this map at first appeared much more precise than both of the other maps. Block D was only covered by maps and , both of which were poorly aligned with the larger maps. was taken at the end of the excavations in this block and thus better showed the extents of the walls; as a result, all features for this block were traced from it.

Chapter 6 Digitizing the Topographic Data

In the last chapter, I showed how I digitized all of the Roman features and some of the Punic ones, and I gave a full synthesis of the existing data for features relevant to the site’s first phase. This information can offer some insight into the site’s layout, but it does not reveal anything about the site’s topography, which is essential for understanding the site’s planning, development, and function, particularly in the Augustan era. As I mentioned in Chapter 1, the Augustan construction of the Byrsa complex required the complete reshaping of the entire hill: the summit was ground down to sterile soil, and the slopes were buried under thick layers of soil and debris. Consequently, the design and construction of many of the complex’s substructures and perimeter structures were largely governed by the initial topography of the hillside.
An archaeological site’s topography can now be reliably recorded in great detail using remote sensing techniques (e.g., photogrammetry, LIDAR), but these have never been applied on the Byrsa Hill. Consequently, the hill’s topography can currently only be reconstructed from published elevation measurements. Such measurements can be found in older publications, such as Delattre (1893a, pl. XI) and Lapeyre (1934, pl. 1, 2), but their low accuracy and poor geolocatability renders them basically useless for my purposes.
163
One exception to this is Beulé’s figure of 19 m for the height of the platform in the southeast corner. This figure seems to have been accepted by Lancel (in Byrsa I, 14), likely because there has not been an opportunity to obtain a better measurement.
Thus, I am limited to measurements published in the Byrsa volumes.
164
The raw data for these elevation measurements have never been published, and I am not aware of any published description of the methods used to calculate them. The latter is a major cause for concern: are the elevations reported relative to the mean sea level of the nearby coast, or to some other standard? Without a comprehensive description of the reference points used in these calculations, it could be very difficult to revise or supplement them with new measurements in the future. As sea levels continue to rise in the next several decades, this problem will only grow worse.
Elevation measurements in the Byrsa volumes are given primarily in maps and profiles, although some can be found in the text. While measurements in maps are very easy to digitize, provided that the map can be georeferenced, it is often difficult to determine what layers or features they are describing, and how the elevation of that layer changes over space. Hence, profiles are more useful for my purposes, because they record elevations that change continuously over space and link them to distinct stratigraphic contexts. In this chapter, I will use the term “profile” to indicate any illustration which has a vertical axis, even if it is a reconstructive or composite illustration, rather than a drawing of a trench wall.
The original goal of this chapter was to digitize all of the elevation measurements that were encoded in profiles in the Byrsa volumes, and to supplement them where necessary with measurements from maps. Due to time constraints, I was only able to digitize the extents of most of the profiles, but these should still prove useful to other scholars who wish to better reconstruct the Byrsa hill’s topography in the future. Moreover, the process of digitizing the extents revealed numerous errors and omissions in the profiles and maps, which seem to have gone essentially unremarked and uncorrected in the 40 years since their publication. While some of these mistakes are minor and can be corrected without much trouble, others can render profiles very difficult or impossible to use.
A full explanation of how I corrected each profile would be prohibitively dense and is outside the scope of this chapter. On the other hand, readers who want to use my digitized profile extents may need to see those explanations, in order to evaluate my results for themselves. Consequently, while I take a mostly synthetic approach in this chapter, I have put full explanations of my corrections for the most important profiles in Appendix D. In the sections below, I will present an overview of the most common types of mistakes, and then discuss two example profiles in detail. In the next chapter, I will argue that these mistakes are reflective of deeper problems in the systems by which archaeological data is published.

The Main Problems with the Profiles

There are 99 distinct profiles in the Byrsa volumes, of which I was able to georeference around 60 (see Figures 6.1, 6.2, and 6.3).
165
Note that this quantity corresponds to the number of profiles that are non-continuous. Some profiles (e.g., , ) are split into two pieces in order to fit on a page.
The other profiles were left out for a variety of reasons, but mostly because their reference elevation could not be determined, because they could not be georeferenced, or because they did not seem relevant for my period of focus, the Augustan era. The profiles that I did georeference are summarized in Tables 6.1 (Byrsa I), 6.2 (Byrsa II), and 6.3 (Byrsa III).
The problems with the published profiles may be divided into three main categories: problems with reference elevation, problems with mapped extents, and problems with symbology.

6.1.1 Problems with Reference Elevation

If a published profile does not explicitly tie some locus to a reference elevation, it can be very difficult, if not impossible, to obtain the elevation data encoded in the original profile. Sometimes, it is possible to get a replacement reference elevation from another profile that is adjacent (e.g., gets 51.92 m from ) or colinear ( gets 50.00 m from ), or from a map that covers the profile (e.g.,

gets 49.70 m from ). But other times, no replacement can be found. This can happen even when there is a covering map, if the elevations are printed illegibly (as is the case e.g., for ),
166
Some of the illegible elevation points in this map can be recovered from and , which reproduce sections of . All of the profiles affected by this reference elevation problem cannot be used anyway, because their extents are not drawn on (which is the only map of this area) and cannot be reliably determined by any other means.
or not at all (as is the case e.g., for and ). This latter case is particularly noteworthy—not a single one of the profiles published for the southwest corner of the Byrsa complex has a reference elevation. It may be possible to determine approximate replacements from profiles and 168a-3, but these are purely reconstructive and were not at all intended for this purpose. As of this writing, I have not been able to identify any elevation measurements in other published descriptions of this area that could be used as replacements for the missing reference elevations. This is a major problem. Without a corrective or supplementary publication from the original excavators of this area, the elevation data encoded in those profiles could be permanently lost.

6.1.2 Problems with Mapped Extents

Many profiles do not have their extents clearly plotted on a map. Generally, their extents can still be determined from a map, e.g., in the boundary of a trench (as with profiles and on map ), or in the outline of a feature (as with profiles and 382-1 on map ). For many profiles, the heart of the problem is in labeling: a profile’s extents are plotted on a map, but the profile itself has no label (e.g., ), or the profile’s label is incorrect (e.g., , , , and ),
167
In these example profiles, the errors are in the grid cell labels, rather than the point labels. That is, for example, ’s point label of “h-i” is correct, but its grid cell label of “E IV 12” is incorrect (see Section D.2).
or the extents on the map have no label (e.g., , , , , , , and ). For other profiles, the heart of the problem is in plotting: a profile’s extents are plotted on a map, but the extents are very imprecise (e.g., , , ) or wrong (e.g., and ; ).
168
As noted in Table 6.1, the extents of are plotted correctly in but incorrectly in . The extents of are shown schematically in —these extents are partially incorrect because they do not indicate that the arch between piles C6 and C7 is shown above the profile segments labeled c-d and d-e.
Finally, for significant number of profiles, the extents are not drawn at all (e.g., and 239; ).
169
Notably in this group are many profiles from Byrsa III that I was unable to georeference: , , , , , , and . All of these profiles fell within the bounds of map , which does not show any of their extents.

6.1.3 Problems with Symbology

Sometimes it is difficult to determine a profile’s extents from a map because the profile is actually more of a perspective drawing, i.e., it is a projection of features from multiple locations and angles onto a single plane. Such drawings can be completely continuous (e.g., ), or they can have discontinuities (e.g., ; , and ; and , , and ). While discontinuous profiles can be straightforward when their extents are properly mapped and labeled (e.g., ), they can be difficult or almost impossible to georeference when this is not the case. This issue can be compounded when the extents are plotted on a map incorrectly (as with ),
170
See n. 168.
or plotted on a map but not labeled (as with ).
171
This last little profile, , was by far the hardest profile to georeference after , requiring probably around 6 hours of work spread out across several working days. This is a great illustration of how perspective drawings, if not properly identified on a map, can be prohibitively difficult for anyone apart from the original excavators to understand and re-use. is not included in Appendix D because the excessively confusing nature of the discontinuities made it too difficult to write up.
Sometimes, discontinuities are not even shown in a profile, even though they are obvious in a photograph: this is the case with , which according to photograph should show a gap between tombs A144 and A154 (these are the Feature IDs from Byrsa II). Because this gap is not shown, and because half of the profile is not captured in the photograph, I did not attempt to georeference it.

Two Big Examples

To illustrate how the problems discussed above can significantly limit the available elevation data, it is helpful to consider the example of two profiles in particular. B1.P.200 is the third-widest profile in Byrsa I after B1.P.134 and (compared to which it is considerably more detailed), and no other profile in any of the volumes stretches closer to the southeast corner of the complex.
172
See Table 6.1 for the exact widths. is very schematic and I have classified it as reconstructive.
is partially colinear with , but extends almost 40 m farther northwest, crossing through a large area (Punic block A) that has no other profiles, making it one of the widest and potentially most important profiles in all of the Byrsa volumes.

6.2.1

The extents of profile are clearly plotted and labeled in map (see Figures 6.4 and 6.5), but several problems make the profile very difficult to georeference. First, mapped extents have a width of 23.91 m on the georeferenced map,
173
This measurement is almost identical to the width of the mapped extents on the printed (i.e., non-digitized and non-georeferenced) map, which is 23.95 m.
while the

Figure 6.5: Profile with annotated measurements and corrected grid cell labels.
printed width of the profile is 22.91 m. Second, the symbology of the mapped extents indicates a discontinuity about 8.25 m northwest of the south endpoint, but the profile only shows a discontinuity 18.75 m northwest of the south endpoint. Third, the grid cell labels given in the profile do not match the grid cells that the mapped extents pass through on the georeferenced map. I found that the most direct way to resolve these three problems was to focus on the third problem, so that is the approach that I will take in this section.
The mismatch in grid cell labels can only be caused by one of three things: a) the grid cells in map are incorrectly labeled, b) the profile extents in map are incorrectly plotted, or c) the grid cell labels in profile are incorrect. I will now consider each option in turn.
  • The grid cells in map are not actually labeled,
    174
    The figure caption of map rather vaguely assigns the map to “secteur H III 2, H III 5,” but these grid cells are not identified on the map.
    but the labels can be determined and applied by comparison with map ;
    175
    There is a single grid label “H” at the bottom of the map, which is basically illegible. It is possible—but much more difficult—to make determine the grid cell labels using map instead of . The grid cell labels of this very large site map () are exceedingly difficult to interpret, but they can be clarified by comparison with maps or . There are no other Byrsa I maps that overlap with and contain grid cell labels. I am amazed at this predicament: in order to simply identify the grid cells in , readers of Byrsa I had to consult at least two different maps, printed in different sizes, styles, and contexts in totally different sections of the book, or else wait for Byrsa II to be published 3 years later. Given the problems I’m discussing in this section, the effect of this barrier seems obvious to me: almost none of the readers, if any, bothered to check the identity of the grid cells.
    the resulting labeled map is shown in Figure 6.4. Therefore, the grid cell labels in are correct.
  • The positions of various features along the profile extents plotted in map can be compared to the positions of corresponding features in profile . In , the distance between the southern side of wall a and the next wall to the south (the ID for this wall is not immediately clear) is about 8.17 m—this is consistent with the distance evident in , omitting the discontinuity indicated by the map symbology. This observation indicates that the discontinuity shown in the map was mistakenly omitted from the profile.

    In , the distance between the southernmost wall (ID again unclear) and the left endpoint is about 4.70 m, which is greater than the distance of about 3.10 m in . This difference would be eliminated if I assumed that the south end of the extents continues another 1.5 cm under and past the map’s smudgy grid label, which is not unreasonable.

    Finally, in , the distance between the northern side of wall a and the right endpoint of the profile is about 7.80m. This is significantly smaller than the distance of 10.31 m in .
    176
    This distance in map is measured from the point where the plotted extents intersect with the north side of a reconstructed segment of wall a—the extant segment is actually 0.84-1.31 m southwest of the plotted extents.
    In the map, if I omit the segment stretching between and 10, which is parallel to the discontinuity farther south, the distance in the map becomes 6.24 m, which is much closer to the distance of 7.80 m in the profile. The remaining difference of 1.56 m is eliminated if I assume that the north end of the extents continues to the middle of the triangle next to the profile extent label A'. These observations indicate that the discontinuity shown in the profile was mistakenly omitted from the map.

    Based on these observations, the profile extents plotted in are basically consistent with the features shown in profile , although some adjustments must be made to the north and south endpoints.
  • According to the grid cell labels in , the profile bisects cistern E1 (labeled only in the profile) longitudinally in .
    177
    It is clear that the bisection is longitudinal because the distance between the cisterns walls in profile is about 1.47 m, which corresponds to the cistern's longitudinal length in map .
    Judging from the maps on which this cistern is plotted (e.g., and ; ), this situation is impossible: the cistern must be bisected in cell . From this, it is clear that at least some of the grid cell labels in are incorrect, rendering the rest of the labels suspect.
Based on the above considerations, it is clear that the profile extents plotted in are basically correct, provided that the northern and southern endpoints are adjusted, and that the grid cell labels in are incorrect. The corrected labels are shown in Figure 6.5.

6.2.2

Profile is presented almost without mention in Byrsa II: it is briefly cited only twice, in reference to the steep NW-SE slope along Punic roads II (Byrsa II, 32) and III (Byrsa II, 46). On the surface, the absence of discussion for this profile seems very strange: at a printed width of 62.76 m, this profile is one of the three biggest profiles in all of the Byrsa volumes.
178
The other two are (printed width 62.75 m) and (printed width 97.90 m). The latter is of limited utility because it is reconstructive and does not include any detail on structures below the level of the pavement.
On close inspection, it becomes clear that features within the first 22.40 m of the profile (beginning from the left endpoint) overlap perfectly with features in . Therefore, the leftmost 22.40 m of are colinear with . The profile’s point labels strengthen this association: for both and , the left endpoint is marked A and the right endpoint is marked A’.
Two main problems make the rest of profile exceptionally difficult to georeference.
179
This profile took at least 20 hours to georeference, spread out over several months.
First, the extents are not plotted on any map. This problem is unexpected, because the profile clearly has point labels, and essentially every other profile with point labels in the Byrsa volumes has its extents plotted on some map. Second, the profile’s symbology does not indicate any discontinuities over the segment that is colinear with , so it is clear that I need to deduce the discontinuities in the rest of the profile myself.
To make the georeferencing process easier to follow, I broke the portion of the profile that was not colinear with into five segments (Figure 6.6). Segments 1 and 2 traverse Punic block C, an area that is covered by many other profiles in the Byrsa volumes, and upon closer inspection it appears that the segments are actually composites of these other profiles. Consequently, I have only georeferenced segments 3, 4, and 5.

Figure 6.6: with segment labels.

6.2.2.1 Segment 5

Segment 5 (Figure 6.7) shows a transverse cut through a cistern (width 2.24 m), almost immediately adjacent to the base of a wall whose width (0.95 m) and top elevation (53.60 m) almost perfectly match those of in map m. In this map, is 0.66 m away from the remains of a parallel cistern whose transverse width of 2.09 m is very similar to that shown in the profile. There are no other walls and cisterns in my initial dataset which match the profile’s features as closely as these, so I must conclude that they are the features shown in the profile, and I digitize the cistern as the following features: , , and .
Given those assignments, it is to determine the identity of the remaining feature. About 0.71 m to the left of the cistern, segment 5 shows a longitudinal cut of a tomb (width 1.92 m). Multiple tombs can be seen around this area in maps and , but only one of them matches the width shown in the profile: tomb A192 in (printed width 1.98 m). Consequently, I conclude that it is the tomb shown in the profile, and I digitize it as .
The assignment of the tomb reveals several important points. Firstly, the cut through the tomb is not parallel to the cuts through and the cistern, so the profile is clearly a bit of a perspective drawing.
180
This contrasts with what was observed with , where all of the pieces of the profile were parallel with one another.
Secondly, the north side of is 3.14 m away from the south side of , which is much larger than the 0.71 m shown in the profile. I conclude that there is a hidden discontinuity in the profile.

6.2.2.2 Segment 4

Segment 4 (see Figure 6.8) shows a wall (width 0.69 m) immediately adjacent to (and left of) a longitudinal cut through a cistern (width 6.62 m), which is almost immediately adjacent to (and right of) a second wall (width 0.66 m). Simply put, this configuration is almost identical to the configuration of walls (, ) and cistern shown in the center of Punic block A in map . Consequently, I conclude that those are the walls shown in the profile and I digitize the cistern as , ,

6.2.2.3 Segment 3

Segment 3 (see Figure 6.9) shows a transverse cut through two parallel and adjacent tombs (combined width 1.77 m), located about 2.55 m from wall of segment 4. This configuration almost perfectly matches tombs A183 and A184 in map . Since no other tombs seem to fit as well as these, I conclude that they are the ones shown in the profile, and I digitize them as and .
The profile indicates a discontinuity at the left edge of , which constitutes the end of segment 3.

Deeper Problems

The last two sections have made it clear that the profile drawings of the Byrsa volumes suffer from numerous problems that make them harder to geolocate and interpret. These problems can obscure or erase the elevation measurements for critical areas of the site, e.g., as happened with and all of the profiles of the southwest corner. The loss of such data should be of central concern to scholars of the Byrsa Hill. Archaeology is a science in three dimensions, especially on this site: the Roman Byrsa complex represents a tremendous stratigraphic project, in which the slopes of the natural hill were blanketed in the detritus of its own destruction, piled in drifts many meters high and subsequently anchored in place with substructures, foundations, and retaining walls. The loss of yet more elevation data threatens to permanently occlude our understanding of that project.
How did these problems happen? Why were they not caught upon publication, or corrected in the 40 years since? I do not believe that I have the final answers to these questions, but I do have some ideas.
Some fault must lie with the strategies and decisions that determined how the Byrsa volumes' text, maps, and profiles were first composed. When an entire excavation report is published without any elevation measurements in its maps or profiles (as with the southwest corner; see Section 6.1.1), or when an entire collection of profiles is drawn without any way to determine their extents on a map (as with the many profiles from Byrsa III: 131-133; see n. 169), or when the grid cell labels in a profile do not match those in the figure captions or text (as with ; see Section 6.1.2 and n. 168), something is wrong with the writeup process itself. The last of those problems, I think, offers some further insight into the situation: the researcher(s) who wrote the captions and text were not the same people as those who drew the profiles and maps.
Some fault also must lie with the publisher's editorial decisions, which determine not just the style and shape, but also (to some extent) the content of the final (yet “preliminary”) site publications. The example of is particularly illustrative in this regard. Why was one of the biggest profiles of all of the Byrsa volumes, which for some areas is the sole source of published elevations data, and which was clearly drawn with point labels and multiple reference elevations—why was this profile not given mapped extents and printed so small that most of the elevations are illegible? The simplest (and, I think, most likely) answer is that the prospect of printing two more large foldout pages, which would have been required to reproduce at the same scale as as well as a map of the extents, was deemed too expensive, since the book already was replete with large fold-out maps and profiles.
181
It is also possible that the profile was deprioritized because its extents were too difficult to understand. As I showed in the sections above, there are numerous hidden discontinuities and some of the segments are not parallel to one another. Moreover, much of the profile seems to have drawn from profiles published elsewhere in the Byrsa volumes, This combination of inaccessibility and redundancy might also explain why there is a lack of engagement with in the discussions and analyses of Byrsa II.
From a financial perspective, the omission of the mapped extents and the shrinkage of make some sense. It is expensive to print large, detailed figures; put another way, it is expensive to print full datasets that ensure a publication’s analyses are reasonably reproducible.
Fault aside, why have these problems not provoked prior criticism? I have been unable to find any publication to date that offers such critique of the Byrsa volumes. Many of the problems I have pointed out seem obvious, given the data that I have shown. And therein, I think, lies the answer: it took five to six months of work for me to be able to begin digitizing the profile extents and collecting those data. Granted, three of those months were spent diagnosing and correcting distortions in Persée’s digitized copies of Byrsa I and III, but even so, the remaining two to three months represent around 300-500 hours of work, several weeks of which was spent reconstructing the reference grid. I think that the main reason no one has previously published such a critique of the Byrsa volumes is that no one else has had the necessary tools, time, and interest. The data in these books had to be fundamentally re-structured before problems could really be identified. This is a major barrier to research on this site.
The existence of this barrier points, I think, to an even deeper issue with how archaeologists manage and publish their data. This issue is tied to the division of labor between archaeologists and technical illustrators, and to the publication paradigm that structures the relationships between archaeologists and their publishing editors. This is the issue that I will discuss in my next and final chapter.

Chapter 7 Conclusions: Reforming the Publication of Archaeological Research

“Final publication begins the day the first pick goes into the ground, indeed, before that, in our conception of the project” (Dever 1996, 43)
“L'Afrique carthaginoise est devenue française : c'est nous, à présent, qui sommes les Romains.”
“Carthaginian Africa has become French: it's us, now, who are the Romans.” (Babelon 1896, 116)
My collation, digitization, and re-organization of the archaeological data on the Byrsa complex have highlighted how recurrent problems in archaeological data management have significantly limited our understanding of the site, particularly in the Augustan period. These problems are long-standing, and they are persistent: while the systematic methods and analyses of the French Mission represent a great improvement over the piecemeal efforts of Beulé, Delattre, Lapeyre, and Ferron and Pinard, their publications suffer from some of the same fundamental problems as their predecessors. At times, these problems overshadow the improvements, because they make it difficult—and sometimes impossible—to critique or confirm old interpretations, or to re-use the data to answer new questions. By re-structuring the data into a single internally-consistent dataset, I have made it much easier to do just that. In this chapter, I will discuss these old problems, new interpretations, and new questions.
Before I begin my critiques, I must acknowledge that much of this work would not have been possible without some major advancements in the open publication of old archaeological publications on the Byrsa. Without the digitization and online re-publication of Beulé (1861), Delattre (1893a; 1893b; 1894), Saumagne (1924b), Lapeyre (1934), and Ferron and Pinard (1955; 1960), most of which are out of print and not commonly held by anglophone universities, my dataset, analyses, and interpretations would have had very little historical depth and the scope of this project would have been greatly reduced. Links to these sources are included in my Bibliography.

Old and Common Problems

Most of the problems with the management and publication of archaeological data on the Byrsa Hill fall into three categories: problems related to the distance between archaeologists and technical illustrators, problems related to the distance between different archaeologists, and problems related to the distance between archaeologists and publishing editors. I will discuss each of these problems in turn.

7.1.1 Distance Between the Archaeologist and the Technical Illustrator

The most visible problems that my study has highlighted concern the collection of published maps and the profiles that make up my initial dataset. Put simply, the geolocatability, accuracy, and symbology of the published maps and profiles are often compromised, making them harder for other scholars to understand and re-use. I believe this results from a general disconnect between the (archaeological) illustrator and the archaeologist (writer). This disconnect prompts the question of what the role of a map should be in an archaeological publication.
None of the early maps of the Byrsa Hill follow a coordinate system, nor do they provide reference datums—perhaps unsurprising, since most of them were produced by architects (e.g., Bonnet-Labranche, Thouverey), rather than geographers or cartographers. Consequently, they are not directly geolocatable.
182
Still, some maps can be georeferenced indirectly, if their features also appear in another directly georeferenceable map. Beulé’s map (1861: pl. I) cannot be georeferenced at all, since it contains numerous distortions and does not have a consistent scale. Delattre’s map (1893a, pl. XI; drawn by Bonnet-Labranche) also provides no datums, and even though it does not show features found by Beulé (despite the fact that they are immediately adjacent to it), it can be indirectly (if poorly) georeferenced relative to some of the substructural walls of the southwest temple in and . Lapeyre’s maps (1934, pl. 1, 2; drawn by Thouverey) can be indirectly georeferenced on the basis of their modern and ancient features. Ferron and Punard’s maps (1955, pl. II; 1960, pl. I) have a coordinate system, but since it is not linked to a standard geographical CRS, they must be indirectly georeferenced relative to features in later maps, e.g., and .
In contrast, the maps of the French Mission were created within a standard geographical coordinate reference system and linked together with a single, site-specific coordinate system, but, as I showed in Chapter 4, the second system was not fully published, and the two systems were never linked in the publications. The biggest improvement in the maps of the French Mission is their accuracy—while it is difficult to find a reference dataset for comparison, their maps are certainly more accurate than those of their predecessors.
183
Beulé‘s (1861, pl. I) map is very inaccurate (see e.g., n. 131). Delattre’s map (1893a, pl. XI), compared to my dataset (which is derived mostly from the Byrsa volumes) is probably accurate to within 3-4 m. Lapeyre's maps (1934, pl. 1, 2), along with his discussion, selectively emphasize certain features to support his interpretation of wall D (Byrsa I, 106-113)—see discussion in Section 5.1.1.1 above, esp. n. 53.
The biggest shortcoming of the maps of the French Mission is their feature symbology, which is often more ambiguous than their predecessors, making it difficult—and sometimes impossible—to distinguish between extant, reconstructed, and hypothesized features.
184
Examples of this include wall G (see Section 5.1.1.2) and the south slope retaining wall (see Section 5.1.1.7, esp. n. 129). The persistence of this problem can be seen in and its derivative maps (see n. 67).
As I explored in Chapter 6, problems with ambiguous symbology can also be found in the profiles of the Byrsa volumes, which often “project” (i.e., unfold) features from multiple different planes onto the plane of the illustration. This process of projection can create discontinuities that are not always shown in the profile (e.g., ), or the mapped extents (e.g., , with extents plotted in ), making the profile much more difficult to interpret. This problem is compounded by another problem, the tendency to not plot and/or label profile extents on a map at all. This omission can make profiles very difficult (e.g., ) or even impossible (e.g., profiles from Byrsa III, 131-133; see n. 169) to georeference. Some profiles that are georeferenceable are still mostly useless, because their reference elevations have been omitted (e.g., profiles for the southwest corner) or made illegible (e.g., ).
In a project of the magnitude of the Byrsa volumes, some inconsistencies and errors are bound to crop up, but the sheer quantity and scale of the problems with the maps and profiles, combined with the disregard for them in subsequent publications, suggests to me that there is a deeper issue at work: those who make the maps and profiles are not the same people as those who write about them.
The simple fact is that since the beginning of the discipline, many, if not most, archaeologists of the Mediterranean have been unable (or unwilling) to draw their own maps and profiles, relying instead on architects, cartographers, or artists for their technical illustrations.
185
The rise of digital recording and drawing techniques has left this traditional division of labor largely unchanged, though the scheduling of that labor has been weighted more heavily towards the post-processing phase.
While this division of labor tends to produce illustrations that are clean, professional, and often quite beautiful, it also creates a multitude of problems, not simply logistical (how does the archaeologist coordinate the illustrators with the excavators?), or ethical (how should the illustrator be credited?),
186
An apt comparison for the question of credit may be found in the film industry. The odds of a technical illustrator for an archaeological publication getting partial authorship are about as bad as those of a visual effects artist for a movie getting included in the opening credits. This runs completely contrary to authorship norms in many natural science fields, where the creation of visual data often requires that one receive partial authorship.
but also, as I have shown through numerous examples in Chapters 5 and 6, epistemological. In the context of the Byrsa Hill, this division is partly why later scholars of the site, when reproducing or citing problematic maps and profiles from the French Mission, have tended not to point out or engage with those problems.
187
The most recent examples of this are in Ennabli (2020, 80 fig. 35 and 90 fig. 41) which respectively reproduce and without acknowledging the ambiguities inherent in each. On , see n. 67. On ambiguities in , see Section 5.1.1.7. On ambiguities in Deneauve's reconstructions more broadly, see Section 5.1.3.4.
More broadly, this division is one of the main reasons why archaeologists very commonly do their analyses and write their reports using maps and profiles that are different from maps they publish. As long as this practice continues, publications will continue to be produced that do not actually report the data on which their results are based.

7.1.2 Distance Between Different Archaeologists

Given that the Byrsa Hill has been the subject of excavations for over 160 years, it is striking, but not surprising, how disjointed and insular the efforts of various researchers have been. Delattre, in his published work, largely avoided the places where Beulé had excavated,
188
Some notable exceptions to this trend include Delattre's (1893b; 1894) excavation of the amphora wall in the southeast corner of the complex, part of which was also found by Beulé (1861, 39), and Delattre's excavations slightly west of the eastern perimeter, which was first excavated by Beulé (1861, 66-74). I have been unable to locate the publications corresponding to Delattre's latter excavations—two articles are listed in Ennabli (2020, 89), but one of them (“RT, 1901, p. 280”) seems to be incorrect, and the other (“BSAF, 1901, 131”) uses an acronym that is not defined in the text.
and the same is mostly true for Lapeyre. Consequently, as I outlined above in Chapter 3, the excavation history of the Byrsa is a patchwork, with excavations conducted all over by different researchers with different motivations, frameworks, and approaches.
The prevailing attitude seems to have been that in places where excavations had already occurred, there could not be any more remains of interest. This attitude is to some extent understandable. Firstly, each of the major campaigns was separated from the others by 20-30 years, and during those interludes features which had been uncovered were deteriorated due to a combination of spoliation and erosion. Secondly, the fixation of all of the excavators on tombs and inscriptions, combined with their penchant for large, open-air excavation methods, all but ensured that no material of interest to them would remain in a given area after a single campaign there.
On the other hand, this attitude was also an outgrowth of the colonial explorer mentality that has characterized most of European and North American archaeological research in North Africa—and many other places around the world—since the beginning of the discipline. Very often, the “discovery” and excavation of a feature bestows some sort of ownership of it, in name if not in deed. This is why scholars still sometimes refer to the apses of the eastern basilica as “Beulé’s Apses,” and to wall D as “Mur Lapeyre:” the association of a publication with a feature or set of features has long been sufficient to warrant subsequent attribution within the archaeological community, and as with appellations coined by other sorts of colonial explorers (Bombay, Mount Rushmore, Lake Victoria, etc.), such names have a tendency to stick. For Delattre and other subsequent excavators, the prospect of re-examining the site of a previous excavation was far less attractive than starting a new one, ideally in mostly unexplored area, where the chances of uncovering new tombs, inscriptions, and impressive architectural features were much higher. This preference for creating personal scholarly domains is evident, e.g., in the idiosyncratic (or non-existent) notation systems used in the different campaigns to refer to specific features,
189
For a brief overview of some of these systems, see Section 2.2.
and in the tendency of each campaign to omit features found by other excavators in their own maps.
190
Bonnet-Labranche, who drew the map published in Delattre (1893a, pl. XI), did not bother to include south perimeter apses found by Beulé, even though they were probably less than 10 m from the apses excavated by Delattre. Thouverey, who drew the maps published in Lapeyre (1934, pl. 1, 2), did not bother to include outlines of walls N, S, O, and other perimeter structures along the southwest and east perimeter, even though he certainly knew about them and they were still visible (1934, 344).
The result of this mentality is that, with a few exceptions,
191
E.g., Saumagne (1924b, 181 plan II) includes features uncovered by Beulé and Delattre along the entire perimeter of the complex (the name of the person who drew this map is unclear). Some of these features may have been assumed.
for more a century, excavations on the Byrsa largely functioned as isolated scholarly domains.
The excavators of the French Mission of the 1970s and 80s were the first to attempt to unify these disparate domains into a collection of more-or-less coherent datasets, which they presented in individually-authored site reports. To some extent, they were successful: this thesis is a testament to that success, since the overwhelming majority of my data are sourced from their excavations. But as I discussed in Chapters 5 and 6, the process of integrating these datasets reveals numerous inconsistencies in the overlaps and gaps between them. Some features are described by multiple excavators in significantly different ways—such was the case with the B piles (made with cement or mortar?) and the E piles (bound with dirt or clay?).
192
On the ambiguity for the B piles, see n. 98. On the ambiguity for the E piles, see n. 88. There is a similar ambiguity for wall D (see n. 55).
Other features are basically not described at all, either due to a simple lack of prioritization, as happened with the south slope retaining wall (see Section 5.1.1.7) and wall G (see Section 5.1.1.2), or due to a misunderstanding, as with the western C piles.
193
As noted in Section 5.1.2.2, Carrié and Sanviti (in Byrsa I, 132) refer the reader to Deneauve and Villedieu's report (also in Byrsa I) for discussion on the relationship between the western C piles and wall N. This is an empty reference, since Deneauve and Villedieu basically do not discuss the relationship.
These problems are exacerbated by the absence of an inventory, index, and precise ID system for extant architectural features in the Byrsa volumes.
194
On this problem in Byrsa III, see n. 152 above. Note that this lack of precision does not extend to the remains of Punic pottery, which are given unique, context-specific IDs, and tombs, which are also given unique IDs and mapped and photographed exhaustively.
The investigations of Roman architecture in these volumes are characterized by a search for extant sections of previously recognized, pre-defined features. Granular identification is eschewed for small, recognizable names such as “wall D,” and “pile C1.” While this system generally works well for a small set of features that are obvious and well-defined—a description which admittedly applies to many of the Roman remains on site—it has some notable shortcomings. First, it does not discriminate between sections of a feature, which creates ambiguities for very large or partially destroyed features (also applicable to most of the Roman remains) and makes it difficult to tell whether a feature under discussion has been actually found, or was only hypothesized or reconstructed. Second, their ID system is not systematically extensible, that is, it does not seem to follow a set of rules that could be used to uniquely identify a large number of additional features. Finally, many important features are not assigned an ID at all, and given the lack of an index or inventory, this can make it very difficult to determine where (or even whether) they are discussed in the Byrsa volumes.
195
See e.g., the many miscellaneous substructural walls discussed in Section 5.1.1.7. The lack of IDs for these features in the Byrsa volumes made this section especially difficult to write.

7.1.3 Distance Between the Archaeologist and the Editor

Many of the problems in the previous two categories are reinforced by constraints imposed by the systems of archaeological publication. A book-length primary site publication cannot be constructed around a systematically extensible feature ID system if the publisher is not willing to provide the editing resources required for a large and robust cross-referencing system.
196
Though this requirement has long been a major barrier to densely-referenced publications, this thesis demonstrates that freely available tools can largely eliminate this barrier for archaeologists who are willing to learn new document-preparation systems.
Similarly, such a publication cannot include a comprehensive dataset if the publisher is not willing to print a large number of high-quality maps, profiles, and many pages of find inventories. While these restrictions are to some degree out of aesthetic or rhetorical concerns, the primary motivation is economic. For essentially all archaeological publishers, the first concern must be whether a product will be financially feasible. When a book’s expected sales are numbered in the hundreds, rather than the thousands, publishers are often unwilling to pay the costs required for overcoming these problems, because their very existence is dependent on how well their products suit the market.
In addition to the economic considerations, there are professional factors at play. For over a century, excavations on the Byrsa Hill were almost exclusively conducted by public officials and priests who were curious, well-connected, and largely untrained. These were amateurs—in the original sense of the word—and their goal was not to compose comprehensive writeups of their excavations, but to communicate their most exciting finds to their wider, and also largely amateur, audience.
197
For a more in-depth discussion of the motivations of these researchers and the demands of their audience, see Gutron (2010). Archaeological amateurism has similarly been investigated in Algeria by Effros (2018).
After Beulé’s singular, self-funded expedition and monograph chapter (1861, 1-84), the next century of publications on the site was dominated by small, bite-sized communications (e.g., Delattre 1893a; 1893b; 1894; Saumagne 1924b) with some very uncommon longer articles (e.g., Lapeyre 1934) or thesis sections (e.g., in Audollent 1901). The systems of archaeological publciation in these decades prioritized small, self-contained preliminary reports, discouraging the collation and organization of data into unified frameworks or archives. Of course, this relationship was complex (excavators had many different priorities aside from publishing), and recursive (the publications that excavators read probably somewhat influenced how they wanted to excavate). Yet, the fact is that no publication longer than Beulé’s monograph chapter was produced until Ferron and Pinard (1955), and no wider-ranging, more comprehensive publication was produced until Byrsa I (published 1979).
It almost goes without saying that the vast majority of the data not published by Beulé, Delattre, Lapeyre, and other excavators has been lost.
198
I am not sure how much archival work has been done to confirm this. Ladjimi-Sebaï (2005, 67 n. 251) indicates that the archives of the Pères Blancs have been searched fruitlessly for maps of the area disturbed by the construction of the cathedral. It is less clear if descendants of Beulé, Delattre, Lapeyre, and other early excavators have been contacted to check for the existence of excavation archives among family heirlooms.
The result of this is that for at least the last 50 years, researchers on the Byrsa have been forced to rely on tiny, scattered, data-poor publications to make arguments that those publications were often never intended to support. As I have shown in the sections above, despite some notable improvements, this problem continued to persist in the Byrsa volumes through the omission of critical data in many of the maps and profiles, and in the absence of a robust feature identification and reference system. This abridgement and lack of structure in the published data is threatening to become permanent, because many of the original excavators of the French Mission have passed away and there is still no publicly-identified, centralized archive of their excavation documents.
199
On the lack of a centralized archive, see n. 2. Serge Lancel passed away in 2005 (Duval 2005), and Jean Deneauve passed away in 2017 (Gros 2018). I am not sure about Jean-Michel Carrié, Nicole Sanviti, Jean-Paul Thuillier, and Françoise Villedieu, who are all co-authors on Byrsa I. I am also not sure about Gérard Robine and Philipe de Carbonnières, who drew most of the maps and figures for the Byrsa volumes. According to Academia Europaea, Pierre Gros remains on faculty as a professor emeritus at Université de Provence (https://www.ae-info.org/ae/Member/Gros_Pierre), but this school no longer exists, having merged in 2012 to become Université Aix-Marseille. According to the Centre Camille Julian, Jean-Paul Morel is also a professor emeritus at the Université de Provence (https://ccj.cnrs.fr/spip.php?article48).

Reforming the Publication of Archaeological Research

As I discussed in Chapter 1, these problems of publication are endemic, not just in the archaeology of Carthage, but in Mediterranean archaeology more generally. Although they have, in some circles, occasionally provoked genuine inquiry (e.g., Frere 1975; Cunliffe 1983; Carver et al. 1992) and introspection (e.g., Richards 2004; Pollock 2010; Morgan 2013), the problems have proven largely intractable, and according to some (e.g., Dever 1996; Shanks 1996b; Herzog 1996), they have grown significantly worse. The lack of concerted research on this topic (with the exception of the edited volumes Shanks 1996a and Shanks and Magness 1999) makes it difficult to definitively confirm such an assessment at the scale of the entire field, but at the scale of subfields and specific sites it is often painfully obvious.
I believe that this predicament constitutes an existential threat to the field, because it threatens our academic integrity, it is incredibly wasteful for researchers of legacy data, and it harms the mental and financial health of the multitude of archaeologists who have not been trained to efficiently and sustainably collect, analyze, and publish data at the scale of an entire site. The threat to our academic integrity has already been pointed out, e.g., by Herzog (1996, 103-104), who noted that absent or incomplete publications create inequities in data accessibility. This makes it very difficult, and sometimes impossible, for other researchers to critique the excavators' results or propose alternate interpretations of their published data, since the excavators are privy to meaningful information that has not yet been published.
200
In Herzog’s assessment (1996, 104), this makes the field of archaeology an “imprecise science,” but I feel more strongly: this makes the field of archaeology not a science at all.
When additional publications are not forthcoming, because the site director has moved on to another project or (more often) passed away, they often take with them an intimate knowledge of the organization and contents of their datasets, leaving behind scant documentation of these topics for future researchers and making the task of consuming, synthesizing, and arranging the remaining data for publication far more expensive than it already was. Sometimes, the cause for such languishing is not that the site director left or passed away, but that they simply cannot manage the data themselves. Perhaps the dataset has become too sprawling and variegated for them to effectively understand (Dever 1996, 42; Jacobs 1996, 71); or maybe they have run out of funding, their grant money having mostly gone toward excavation (Mazar 1996, 27; Dever 1996, 40); or perhaps the prospect of organizing, tabulating, composing, and typesetting their data and analyses, with no guarantee of a publisher, for years on end, has simply (and quite understandably) overwhelmed them—as Shanks (1996b, 51) puts it,
“The archaeologists who fail to publish are not, for the most part, bad people. They are not disinterested or intentionally neglectful or lazy. They fail to publish, for one reason or another, because they can't. They simply cannot do it. It is a mountain they cannot climb whether for legitimate or psychological or other reasons. In short, they need help. And it should be the task of the profession to find some means to give them that help.”
This crisis requires a combination of solutions. First, we must rethink and redefine what it means to properly publish archaeological research. It has been clear for quite some time that the monograph is not well suited to the task of publishing data at the scale of a site. It is terribly tedious and inefficient to typeset thousands of pages of documentation, drawings, and spreadsheets into a manuscript, and it is terribly expensive to print it. The rise of digital publication technologies has offered an unprecedented opportunity to rethink the publication norms of our field, enabling researchers to forego the costs of printing and to use more flexible formats than manuscripts. These formats include self-published online databases (e.g., Bates 2019; Manière, Crépy, and Redon 2020), interactive site maps (e.g. Aksoy and Bayar 2016; Townsend et al. 2020), and linked-data e-books (e.g., Opitz, Mogetta, and Terrenato 2016). Unfortunately, such technologies remain significantly under-used, in no small part because they tend to be under-represented in Review, Tenure, and Promotion (RPT) requirements. There needs to be a concerted effort to redefine RPT requirements to encourage such publications.
Second, there must be a curricular shift toward data management and digital publication. Far too many archaeologists, particularly in the Mediterranean, never complete coursework on data management. Instead, they learn the data recording and organizational strategies of their advisor, or perhaps their colleagues, on the fly. Without formal training, it can be difficult to create a data management plan that is comprehensive (describing all data collected within the project), easy for other researchers to understand, flexible enough to accommodate the addition of new types of data, and systematically extensible to a sufficiently large number of loci. Similarly important (and under-used) is coursework on digital publication. All of the digital publishing formats mentioned in the previous paragraph require a significant amount of training to create, and if researchers do not have at least some experience with them, they are unlikely to seek out such training on their own. Moreover, it is often very difficult for an archaeologist to effectively use such technologies if she did not factor them into her original data management plan.
Third, we must change the mentality—still all too common in our profession—that the publication of site reports represents a necessary evil and the “last stage of research” (pace Herzog 1996, 88). Complete and open communication is essential to scientific inquiry and academic community. If it is prohibitively difficult to communicate one’s data completely and openly, then something has gone wrong. Doing archaeological research should be predicated on participating in the archaeological community—in other words, excavation should be predicated on publication, not the other way around. The reticence of many project directors toward full publication belies the nature of the threat posed by publication delays: the greatest risk of a project director moving on or passing away is not that their interpretations will be lost. The greatest risk is that their knowledge and understanding of the data recording, collection, and structuring schemes will be lost, that future researchers will not know where the excavation records are stored, how they can be accessed, or how they are organized. This is how unpublished excavation records vanish: when the people who created, organized, and used them have passed away, their unorganized papers and undocumented personal archives are left to colleagues and relatives to whom they have little or no importance, and who eventually place them in perpetual storage, or worse, throw them away. Data must be published before they are actually useful, or as Dever (1996, 47) puts it, “unpublished data are not data at all.” Publication represents the first stage of research, not the last.
In this thesis, I have demonstrated that it is possible to restructure old archaeological data in a sustainable and systematically extensible way.
201
Two computational tools were essential in this work. The first tool was QGIS, a geospatial mapping program. As I have shown many times in the preceding chapters, previously published maps of the Byrsa have too many inconsistencies for any one of them to be completely reliable, and GIS software made it generally straightforward to identify and resolve those inconsistencies. Another essential tool was LyX, a document preparation program. The simple truth is that this thesis could not have been written in Microsoft Word. There are too many figures, tables, bibliographic links and cross references for Word to reliably handle, and the proprietary formatting of .docx files ensures that it is all but impossible to fix references if they break or retrieve data if the file becomes corrupted. By using LyX, an open-source What-You-See-Is-What-You-Mean word processor built on the LaTeX document preparation system, I had access to extremely robust cross-reference and hyper-reference systems, all while writing plain text-formatted files.
There are undoubtedly flaws and gaps in my work, but I was still able to resolve many of the problems inherent in prior publications. I have also demonstrated that the restructuring of old data can give rise to new interpretations and questions about a site, some of which were not possible within the old organizational framework. In the final section of this chapter, I will discuss some of those interpretations and questions for the Byrsa Hill.

What can we do with Restructured Data?

The restructured dataset has enabled new interpretations about the design and development of the Byrsa complex, particularly with regards to the substructural walls and perimeter structures in and along the complex’s southern side. Some of these interpretations require additional proof, highlighting certain areas of the site and certain questions for further investigation.

7.3.1 New Organization Enables New Interpretations

The most significant new interpretation that I have proposed above is that the Phase 1 substructural systems and perimeter structures and of the Byrsa complex were constructed in a modular, piecewise fashion. This flexible approach allowed construction crews to adapt more easily to the local availability of stone rubble from the Punic destruction layer, while still following the original design of the complex. The approach is evident in wall D’s variable and somewhat crooked construction, both of which were obscured by the reductive symbology used to depict it in the maps of the Byrsa volumes. The approach is also evident in the vastly different dimensions and construction of the apses lining the southwestern, southern, and eastern apses. The apses of Series 1 and 2 were significantly wider and had much thinner walls than the apses of Series 3.
202
Not counting the hypothetical rectilinear wall outlines that are shown without explanation in Morel (2011a, 327 fig. 1)—see n. 125.
The apses of Series 3 themselves exhibited a remarkable shift in dimensions, growing significantly wider from west to east, and they seem to have been significantly longer than the apses of Series 4, although I believe that this last discrepancy may have been at least partially made up for by a now-missing stone lining. This interpretation contrasts with previous characterizations (e.g., Deneauve 1990) of the Augustan-era construction project, which have emphasized the unity of the complex's design and execution.
I have also proposed several smaller interpretations that still want for additional proof. First, I showed that the late dating of the B piles that was proposed by the original excavators seems questionable, and I suggested some reasons why a Phase 1 dating may make more sense. Second, I proposed an order and rationale for the development of the substructural walls of the Phase 2 southwest temple, and showed how the interaction between these walls and the B piles and C piles was probably more complicated than previously acknowledged. Third, I reconstructed the approximate extents of the amphora wall in the southeast corner of the complex, and showed that it may have functioned in concert with the southeast staircase nearby. Finally, after pointing out that the previously proposed dimensions of the Phase 1 eastern apses have no basis in material evidence, and in fact contradict the construction strategies used in the southwest corner of the complex, I hypothesized that the Phase 1 dimensions may have been identical to the Phase 2 ones.

7.3.2 New Interpretations Prompt New Questions

These preliminary interpretations and hypotheses highlight the attractiveness of certain areas of the site for further investigation, and prompt new questions about the complex’s design and development. A fuller excavation (and publication) of the substructural walls of the Phase 2 eastern basilica would probably provide helpful constraints on the dimensions and design of the building’s Phase 1 predecessor, particularly in the southwest corner, where the building’s substructures met wall D’ (built in Phase 1). A new field survey of the substructural walls of the southwest temple would clarify their extents and their stratigraphic relationships with one another, which would in turn clarify their order of construction; an archival survey could supplement the fieldwork with elevation measurements from the primary excavation documents on this sector. Targeted excavations around the southeastern perimeter would almost certainly clarify the (very hypothetical) layout of this part of the complex, including the original extents of the amphora wall and the original dimensions of the apses and/or other retaining walls, but this entire area appears to be underneath modern homes and businesses, so even limited excavation is unlikely to be possible in the foreseeable future.
The complex’s design and development could be greatly clarified by making a serious investigation of the structural requirements imposed by topography of the Punic destruction layer and the volumes of earth and debris found above it. In the past, excavators have tended to make vague statements about the role of the apses, the substructural walls, and the foundation piles in resisting outward pressure from the Augustan embankment. These statements are very shallow, from an engineering standpoint. What sorts of pressures did these structures need to resist? How large were they, and in what directions? How did these pressures change over time, as the soil naturally shifted, compacted, and creeped? How did these changes influence the decisions which governed the construction of Phase 2 structures? These are necessary questions, but they cannot be answered without a comprehensive dataset describing the topography of the Punic destruction layer and the vertical and horizontal extents of all of the Roman and Punic features. As my preliminary work in Chapter 6 seems to indicate, such a dataset may well be obtainable at least for the southern part of the complex.
Such a dataset could also reveal how the Phase 1 Roman construction crews navigated the site’s Punic remains. By integrating the horizontal and vertical extents of both Roman and Punic features, we could determine how the various Roman substructures cut, abutted, and included Punic walls, cisterns, tombs, and other features. This would offer insight into what sorts of Punic features the Phase 1 Roman construction crews would have seen during their work, and what they, or their superiors, decided to do about them. Which Punic walls were removed to make way for Roman ones, and which ones were merely included? How many tombs did the construction crews encounter, and how many did they fully or partially destroy? How might the presence or discovery of tombs have influenced the construction decisions that followed—e.g., as in the southwest temple? These, too, are necessary questions, which cannot be answered without restructuring the current architectural dataset for the Byrsa complex.
These questions touch on a deeper theme underlying the foundation of the Roman colony at Carthage, a theme that has been largely neglected by modern scholars of this site: the role of reconstruction and erasure in shaping public and private narratives about the past and present. Still bearing the physical and psychological scars of the recent violent upheavals at the end of the Republic, the Romans who labored on the colony’s foundation literally took apart the remains of their country’s greatest geopolitical rival—and deeply despised nemesis—stone by stone, and then they re-made the city in Rome’s own ideal image. What did this project mean to the laborers, surveyors, architects, artisans, and soldiers who undertook it? What did it mean to their families and children? How did it influence their perception of the new political order? These are questions that can and should be asked of this site. By collating, digitizing, restructuring, and re-publishing archaeological data from the Byrsa Hill, I have begun to make that asking possible.

Appendix A Correcting Distortion in Figures from Persée

Summary of the Problem

One of the most important repositories of scholarship on ancient Carthage is Persée, an open-access digital library that contains an enormous selection of books, conference proceedings, and journal articles spanning over 200 years of French archaeological research. Particularly useful is Persée’s selection of books and articles on the Byrsa Hill, which include Byrsa I and III (curiously, not Byrsa II), and several key studies in Comptes Rendus des Séances de l'Académie des Inscriptions et Belles-Lettres (CRAIBL) and Cahiers des Études Anciennes (CEA), including Deneauve (1983) and Gros and Deneauve (1980). All of these publications have been manually scanned, de-skewed, and optimized by Persée, and are available for download as OCR-enabled PDFs.
A significant number of figures in these PDFs are visibly distorted. Three examples of distorted images from the Persée PDFs (, , ) are given in Figure A.1, with perfect squares shown in red for comparison.

In the interest of concision and clarity, all images will be referred to by a three-part ID, which indicates the publication from which the image was taken, the identity of the scanner, and the page number from the publication. See Section 2.1 for a full explanation of this notation.
In all three examples, it

is clear that the reference grids are not square.
These images are not distorted in their original paper publications. In Figure A.2 are shown the same images as in Figure 1, but scanned instead by me (, ) and a librarian from Koerner Library (). As before, perfect squares are shown in red for comparison. In all three examples, the reference grids are perfectly square. Notably, physically measuring the images in the printed books yields the same result—the reference grids ought to be square in the Persée PDFs, but they are not.
This image distortion is a major problem, because the distortion is not slight. As will be shown below in Figures 5-7, features in depicted in the Persée PDFs diverge wildly from their personally-scanned counterparts. These distortions are present in multiple publications (Byrsa I, Byrsa III, andGros and Deneauve 1980), across multiple years (1979, 1985, 1980), and in multiple formats (book and journal article). This suggests that the

Figure A.2: Three pages from personally-scanned PDFs that do not exhibit distortion. Perfect squares are shown in red.
distortions present in these PDFs may be found in many other documents in the Persée system.
In the following sections, I diagnose the cause of the problem and demonstrate a solution.

Diagnosing the Cause of the Distortion

A close examination of the three examples discussed above suggests a common cause for the distortion: all of the examples are composed of non-square pixels. Figure A.3 shows a close-up perspective on each of the three example pages from Persée, with perfect squares shown in red for comparison. In all three examples, it is clear that the pixels themselves are not square. Pixel aspect ratio (AR), calculated as the ratio of pixel width (w) to pixel height (h), is calculated for each page in Figure A.3. These AR values vary significantly. In and , the pixels are taller than squares (AR < 1), while in the pixels are shorter than squares (AR > 1).

Figure A.3: Close-up view of the three example pages shown in Figure A.1. Perfect squares are shown in red. In all three pages, the pixels are not square.
Although square pixels are generally the norm, digital images may be encoded with different pixel aspect ratios when created in certain contexts and for certain purposes. Even so, the pixel aspect ratios calculated from Figure A.3 are very different from one another, and they do not match any of the standard non-square values used in common image and video formats. Moreover, a quick survey of other pages in Gros and Deneauve (1980), Byrsa I, and Byrsa III shows that every page is composed of pixels with a different aspect ratio. These factors suggest that the different aspect ratios may have been produced accidentally, perhaps during the post-processing of the original, unoptimized scan files.
The next step was to export the three Persée PDF pages as JPEG image files, so that key features in them could be traced and overlaid onto the pages I personally scanned. By examining the sizes of the gaps between the two sets of features, it is possible to determine if the mismatch is due only to a difference in pixel aspect ratio, or if there are additional sources of distortion.
When the three PDF pages are exported as JPEG files, the non-square pixel aspect

ratios are retained. The metadata of the resulting files are presented in Figure A.4.
Notably, the JPEG files for and are encoded with pixel aspect ratios that are the mathematical inverse of what were calculated from Figure A.3. This is caused by an unreported bug in my PDF viewing and editing program, Adobe Acrobat Pro: when a rotated page is exported to an image file, Acrobat exports the rotated image, but encodes that image with the non-rotated metadata. Both and were originally oriented 90 degrees counterclockwise to their orientation in the Persée PDFs—when creating their PDFs, Persée rotated these pages 90 degrees clockwise so that their figure captions would be right-side-up. This means that exporting these pages from the Persée PDFs yielded images that were rotated, but also encoded with the non-rotated (i.e., non-inverted) pixel aspect ratios. This problem is solved by rotating the PDFs of and by 90 degrees counterclockwise before exporting them as JPEG files. From this point forward, all exported images of these pages were made using this method.
In the resulting JPEGs of , , and , key features were traced, and the traces were overlaid on corresponding JPEGs generated from my personally-scanned PDFs. The results are shown in Figures A.5, A.6 and A.7.
In each Figure, the trace was overlaid in such a way that one point from it overlapped perfectly with its corresponding point in the image below. I then measured the distances between this shared point of optimal overlap and five features. I calculated the gaps between these two sets of distances, and plotted them against the distances for my personal scan. In each case, the resulting plot was completely linear (R² > 0.99), indicating that the mismatch was caused by a different linear scaling factor. This limits the potential

causes of the mismatch to differences in pixel aspect ratio and image resizing, and rules out non-linear causes such as excessive page curling. In each case, the slope of the plot is essentially equal to the difference between the Persée aspect ratio and 1, which shows that the gaps are caused entirely by a difference in aspect ratio.

Demonstrating a Solution

Because pixel aspect ratio is solely to blame for the mismatch, the solution to the problem is simple: edit the metadata of the Persée JPEGs and set the pixel aspect ratio to 1. Image metadata is stored in EXIF format, and can be edited in a variety of ways, including via image editing software (e.g., Adobe Photoshop), EXIF editing software (e.g., EXIF Pilot), and python scripting (e.g., with the piexif package). Adjusting the image metadata in this way yields an almost perfect overlap, as shown in Figure A.8.

Appendix D Corrective Notes for Previously Published Profiles and Maps

While determining the extents of the profiles, some inconsistencies and ambiguities became evident. These are identified below, along with the solutions I used to resolve them. In this appendix, I always use the term “trench” to refer to a unit of excavation, unless otherwise specified. This is equivalent to the term “sondage” in the original French.

Byrsa I

D.1.1 The extents of profiles and are missing

The extents of and (both 4.00 m wide) are not labeled on any map, though their figure captions give their orientations (west and south) and assign them to . A trench is shown in this location in maps , , and , but it does not have a south wall with the correct dimensions and it does not have a west wall at all. Based on photo , the extents are located a fraction of a meter (I assumed 50 cm) inward from the western and southern boundaries of .

D.1.2 The extents of profile are missing

The extents of (4.00 m wide) are not labeled on any map, though the figure caption gives its orientation (west) and assigns it to . A trench is shown in this location in maps , , and , but it does not have a west wall. Based on photo , the extents are located a fraction of a meter (I assumed 50 cm) inward from the western boundary of .

D.1.3 The extents of profile in the given maps are incorrect

In profile , the rightmost limit, denoted C, is 2.80 m away from B, which marks a bend in the profile wall. This does not match the extents of the profile as they are plotted in maps and , where C is shown almost 6 m away from B (and immediately adjacent to “coupe 20”). In contrast, in the distance between B and the leftmost limit, A, is 6.20 m, which is identical to the distance shown in and .
The contexts and features in appear to be completely continuous, so C in must really be 3.80 m away from B. I conclude that the profile extents plotted in and are incorrect, and I resolve this problem by following the extent in only to 3.80 m north of B.
204
It is surprising that this mistake made it into two different maps of the sector. Perhaps originally covered the full distance shown in and , but was cropped during the editing process to fit within page boundaries—this would especially make sense if the authors originally intending to print as a fold-out figure, but were forced to limit it to the size of a normal page.

D.1.4 The extents of profile are not clearly identified

There is no label for profile that can be used to link it to extents plotted in maps and , and no grid cell labels appear in the corresponding text, either. Two observations are sufficient to link to the m-n profile in : their widths are equivalent (just under 8.00 m), and the placement of features in the former is identical to the latter.

D.1.5 The scale given for profile is incorrect

The figure caption for profile gives a scale of 1:100. No scale bar is given, but the scale can still be checked against the dimension labels at the bottom of the profile. As it is printed, 520 cm (horizontal) in the profile measures 4.55 cm on the page: the correct scale is about 1:114.3. This distortion appears to be identical in the vertical direction. It seems likely that this distortion arose during the printing process: perhaps the publisher shrank the profile so that it would fit better within the required margins.

D.1.6 The scale given for map is incorrect

The figure caption for map gives the scale as 1:50, but as it is printed, 5.00 m on the map (the side length of one grid cell) measures 5.00 cm on the page. Therefore, the scale is actually 1:100.

Byrsa II

D.2.1 The extents of profile are not clearly identified

The extents of profile are not plotted on any map, but its width (4.38 m from the edge of pile C16) is consistent with a line between the southeast corner of pile C16 and the southeast edge of the excavations shown on map (staying within the bounds of ). This assignment is also consistent with photographs and .

D.2.2 The extents of profile are not clearly identified

The extents of profile are not labeled on any map, but its width of 7.40 m almost perfectly matches the length of the southwest limit of the excavations in . Photographs of the profile wall ( and ) are consistent with this assignment.

D.2.3 The extents of profile are not clearly identified

The extents of profile are not plotted on any map, but its width (2.61 m) and features are consistent with a stretch of the northeast limits of Punic block C excavations shown in . Photographs , , and are consistent with this assignment.

D.2.4 The extents of profile are missing

The extents of profile are not plotted on any map. Its width is 3.97 m, the distance from its south limit to the south side of the wall is 1.62 m, the distance from the north side of the wall to the profile's north limit is 1.84 m. There are no gaps or bends in the profile. Based on these factors and photographs , , and , it appears that the profile is located on the east side of courtyard E in Punic block E.

D.2.5 The extents of profile are not clearly identified

The extents of are not labeled on any map, but its figure caption and width of 4.28 m are consistent with the easternmost limit of the easternmost trench in —note that this means the profile stretches about 30 cm into , even though its label only specifies .

D.2.6 The extents of profile are not clearly identified

As with , the extents of profile are not labeled on any map. The profile's width of 9.95 m is consistent with the westernmost limit of the easternmost trench in map , provided that the profile stops 40 cm south of the northwest limit. (This is consistent with 's label (“ - ”), since that extra 40 cm extends into .)

D.2.7 The extents of profiles , , and in the given map are incorrect

The extents of profiles , , and are plotted on map , but only in schematic fashion: their widths do not match the widths of the profiles. I transferred these extents in over to and adjusted them so that they match their respective profiles' widths and features.

D.2.8 The grid cell label for profile is incorrect

The grid cell label of profile is inconsistent with the extents plotted on map . On the map, the extents stretch into , even though the profile is only labeled .

D.2.9 The extents of profile in the given map are incorrect

The extents of profile are plotted on map , but in exceedingly schematic fashion. I adjusted the extents to better reflect the width and features illustrated in the profile.

D.2.10 The grid cell label for profile is incorrect

The grid cell label for profile is inconsistent with the extents plotted on map . On the map, the extents stretch into , , and and , while the profile's label only specifies , , and . Note that has some discontinuities: it displays part of wall C, an arch between piles C6 and C7 located in . which is disconnected from the other features.

D.2.11 The extents of profile in the given map are incorrect

The width of profile (1.68 m) does not match the width of the extents plotted in map 1.93 m). This is strange, considering that the width of neighboring profile (4.19 m) almost exactly matches the width of the extents plotted in (4.20 m).
It might seem that the scale bar for profile is incorrect, because the width of the grave in is 1.32 m, which is very different from the width of the grave in map (0.72 m). This is not the case, because in the profile the trench measures 4.25 m deep, and this measurement is confirmed in the discussion on p. 266. The grave at the bottom of is drawn such that both of its ends are depicted in dotted lines.
The contradiction over extents can be resolved thus: in map , the profile should begin at the southeast edge of the trench extents (dotted line), and continue on a line toward x' until it reaches the closest point to the southwest corner of grave A325. That yields a width of1.72 m, which is almost identical to the width of profile (1.68 m, as noted above).

D.2.12 The extents of profile are missing

The extents of profile are not plotted on a map, but the profile's width (1.79 m) and features are consistent with the east wall of trench 2 in , if it is extended about 60 cm to the south.

D.2.13 The extents of profiles cannot be georeferenced from the given map

The extents of are plotted on , but this map is not reliably georeferenceable. They must be transferred over to the corresponding location on map , which is georeferenceable.

D.2.14 The grid cell labels for profiles and are incorrect

The grid cell labels for profiles and say that they are located in and , but the profiles are actually located only in .

Byrsa III

D.3.1 The extents of profile are not clearly identified

The extents of profile (width 7.39 m) are not labeled on any map, but they correspond almost exactly to the east wall of a trench at the mouth of the first apse north of the central apse on . The grid cell labels for are consistent with this assignment.

D.3.2 The extents of profile are not clearly identified

The extents of profile (width 3.43 m) are not labeled on any map, but they correspond almost exactly to the south wall of a trench at the mouth of the first apse north of the central apse on . The grid cell labels for are consistent with this assignment.

D.3.3 The extents of profile are not clearly identified

The extents of profile are not labeled on any map. According to the profile's figure caption, the profile follows the wall of the modern staircase in the second northern apse. By counting the stairs visible in the profile and comparing them to the stairs visible on map , I can constrain the extents to about 10 stairs (2.79 m) at the mouth of the apse. This is consistent with the profile's width of 2.92 m. Note that this means that the profile's extents stretch 40 cm into , even though this grid cell is not included in the profile's grid label.

D.3.4 The extents of profile are missing

The extents of profile are not plotted on any map. The profile stretches 7.87 m from the outer edge of the basilica's east facade into cardo IV east, and 21.26 m from the building's western facade into the paved area behind it. I assume that the profile follows the axis of the decumanus maximus. The profile's extents can be reconstructed on the basis of these observations.
