Welcome to Constantinople as Palimpsest.

Constantinople as Palimpsest is an in-progress place-based student-created digital encyclopedia of Byzantium. It was created by the  2015 ,  2017 , and  2020  Wesleyan University students of  Prof. Jesse W. Torgerson , integrated with and supported by the student researchers and GIS tutors of the  Traveler’s Lab . Please read about the original development of this encyclopedia project  here .

The goal of this encyclopedia is to give students, and the public in general, access to what scholars have uncovered about the medieval life of the city of Constantinople in an interactive format that inspires exploration, and even play.

The design was inspired by the concept of a palimpsest. A palimpsest is a page that has been erased (or, in the case of leather parchment, scraped with a knife) to remove an original text and thus make way for a new one. As a metaphor, palimpsest "lends itself especially well to the interpretation of architectural monuments and landscape sites" (see:  Aksamija, Maines, Wagoner ) because it encourages us to always be mindful of changes in appearance and usage over time. While this beta version of our place-based encyclopedia is still not able to take time into account (it presents every item from the millenium-long history of the Byzantine Empire as though all were equally present at the same time) this remains a goal for future publications of the project.

Please scroll down to read about the goals of this project, and how to use the resource, or click on the content bar above to skip straight the topical sections of this publication.

The encyclopedia will be updated and re-published in the Spring of 2022. In the meantime please contact  Jesse W. Torgerson  with questions or feedback.

How to Use?

Our goal is to make it possible to discover the Byzantine (Roman) Empire in general, and the city of Constantinople in particular, through a re-presented historical space, rather than in the abstracted context of traditional textbooks and encyclopedias. Our goal is to make it possible for novice students of Byzantium to explore a historical image of Constantinople in the way that the city lives in the imaginations of scholars: as an interconnected, integrated, lived space.

The traditional heading-based encyclopedia is not a helpful introductory tool. Traditional encyclopedias (even digital versions such as Wikipedia) require the reader to already know something---often quite a bit---about what they are looking for. Even advanced scholars using encyclopedias will usually tread familiar trails over and over again, looking up entries they know to find links to ones they don't, rather than reading ecumenically to discover and explore. Maps are much easier ways to orient oneself (quite literally!) to an unfamiliar field of study, and they are a dynamic means to re-conceptualize and re-organize information learned via other formats.

How do I use the Encyclopedia, and read its entries?

Knowing our process of creation can help guide use. Alp Eren used ArcGIS to draw the base map behind all of the topical maps below. Eren's map is based on Kostas Plakidas'  digital map of Constantinople published to Wikimedia Commons , itself based on Raymond Janin's  Constantinople Byzantine . Wesleyan University students then added clickable over-drawings to the map in ArcGIS online's map notes feature. These appear as green lines, points, and polygons.

When any green line, point, or polygon on the map is clicked, it activates a small pop-up window (note: pins or points respond to being clicked at their base rather than on the sphere at the top of the post). These pop-up windows contain a description and images (where possible or relevant) of the site or item in question. In each entry the item is briefly defined and dated, followed by a fuller commentary, and then a bibliography of relevant images and sources.

Each item is catalogued: by its name, by the nature of our knowledge of it in the present, and by its date. First, there are four categories for item "type". These are:

  • Site—forum, harbor, palace, etc.
  • Region—neighborhood, geographic area, etc.
  • Monument—obelisk, church, etc.
  • Object—statue, lamp, hairpin, etc.

Then, there are three categories for nature of survival. These are:

  • In Place (IP)—intact/visible; object never been moved
  • Displaced (DP)—survives but moved or only traces remain
  • Textually Attested (TA)—completely gone, but texts attest

Thus, the label on the item already opened just below--"Monument IP_Column of Constantine_330"--tells the reader that this is a surviving Monument that is still In Place and so can be seen (at least mostly intact) in-person today, and is identified as the Column of Constantine raised in the year 330.

Who is the Encyclopedia for?

Constantinople as Palimpsest can serve a wide range of readers and agendas equally well.

Persons with no knowledge of Byzantium at all can walk (i.e., scroll) through the re-presented medieval city by simply working through our curated, manipulable maps (see the topics above): zoom in and out, drag the map across their screens, and click on items that look interesting. Size is a fair guide to introductory-level importance. By clicking on the largest items on Monumental Architecture map (for instance), one will discover the main routes in the city, its walls and harbors, the Hippodrome and major Fora. This provides a good basic orientation to the layout of the City, and a context for working through the smaller items expressed as green "pins"--statues, columns, fountains, gates, etc.

On the other hand, experts in Byzantium will benefit from finding what they already know in a new form. Ordering artefacts by historical location rather than historical narrative, disciplinary focus, or alphabetical order opens up a field in which alternate associations and ideas can germinate. As the map continues to be more fully populated, scholars will increasingly be reminded of neglected or forgotten material.

Monumental Architecture

From its origins as Byzantium to the Late Empire, Constantinople has been home to some of the world’s finest and grandest monuments. From the hippodrome to the forum of Constantine, the monuments of Constantinople were major spaces for Byzantines to engage in public life, and spaces for their imperial patrons to control and promote their ideologies. Through these monuments, readers can track the historical development of the city, with many of these monuments being constructed between the 4th-7th centuries, during the territorial height of the Empire.

This map provides an introductory sampling of some of the notable monuments and structures of Constantinople. Readers may find especially interesting the hippodrome and forum of Constantine, both of which provide detailed entries on the sites and artwork present within each monument. Also of interest are the Theodosian Walls of Constantinople, which highlight the military history and longevity of the empire. 

Readers may also wish to consult the Exchange Economy and Imperial Presence, as the sites in these sections shed light on how Constantinople’s monuments interacted with the city’s global economy, and the imperial bureaucracy.

 

 

 

Imperial Presence

One cannot discuss the growth and development of Constantinople without considering the city’s role as the home of the imperial bureaucracy and the Emperor. Almost every emperor and their administration left their mark on the city from the forums they established to the churches and monasteries they founded. From the artwork to the presence of imperial events and figures a resident of the city could not have avoided the presence of the state.

Major social centers and spaces give the impression of how the public, the aristocracy, and the imperial administration interacted with one another. This newest and ever-expanding section also hopes to live an imprint over how an emperor and his courtiers left their mark on the city, and how they, their predecessors and successors may have “walked” the city. Ultimately, the map shows how the political institutions and changes of Constantinople and the Byzantine Empire correspond with the landscape of the Basileuousa (Queen of Cities)   

Readers may also wish to consult the Exchange Economy and Monumental Architecture sections, as the sites in these sections shed light on how the imperial administration and the emperor left shaped the major public and economic sites and centers of the city.

Administrative Regions

Administrative Regions:

The Notitia Urbis Constantinopolitanae

This map is a visualization based on the information contained in a document that purports to have been created under Emperor Theodosios II (r. 416-450) in 425. It takes for granted a division of the city into fourteen regions, and catalogues the urban features of each of these regions. Despite the fact that the regions supposedly date back a century to the reign of Constantine the Great (d. 337), there is no corresponding late antique map or detailed text that articulates exactly where these regions lay. Scholars have made various attempts at reconstruction, and the regions that we have re-drawn simply represent a working consensus. The full title of the document in question is:

Notitia Urbis Constantinopolitanae: Urbs Constantinopolitana Nova Roma

Or,

Register of the city of Constantinople:

The City Constantinople, New Rome

Clicking on each region will highlight its outline, and provide the information from the Notitia as well as a brief commentary composed by a student researcher.

There have been many attempts to make use of the information in the Notitia as there is no other surviving survey of the city with such detail. At the same time, even the Notitia leaves much to be desired, and even the information it provides is difficult to interpret into real economic terms.

Readers should consult as starting places:

Private Life

It is extremely difficult to generate an image of what might be thought of as private life -- at any social level from "the poor" (πτωχοί) to the imperial family -- for the Byzantine period. No text such as Xenophon's Oikonomikos exists that would allow us to feel as though we are peering into the daily life of an elite household, and pieces of information that can be garnered refer almost entirely to the imperial family whose lives by definition were not "private."

The items placed on this map are few, but represent student researchers' work to present a range of items, places, and scholarship that might be pieced together as the beginnings of a mosaic of private domestic experiences.

Insulae (modeled on analogy from those that have been studied at Roman Ostia) and Palaces represent living quarters for those we might think of as being in the "upper" and "middle" classes. Correspondingly, hostels, hospitals, orphanages, and almshouses represent a sampling of possible living quarters for the dependent and powerless residents of the city.

Gardens, baths, fountains, and the hippodrome give the beginnings of an impression of where public congregations and meeting places (whether planned or accidental) might have occurred, and where the city's residents may have spent their leisure time when not at home.

Readers will want to compare the impression generated by this information with that generated by the Exchange Economy and Religious Life maps, as the information collected in those places is obviously relevant for imagining what a citizen of Constantinople might find themselves doing on any given day.

Exchange Economy

Exchange Economy

Goods and people flowed into and out of Constantinople: from the gates of the city down the more heavily trafficked northern branch of the Mese; from the northern and southern harbors into the central Mese and the Portico of Domninos along the great columned commercial main street of the Makros Embolos; and, from myriad local centers of industry and production.

This map provides an introductory sampling of some of the features of this commercial and economic life. Readers may find especially interesting the recent shipwreck discoveries in the Harbor of Theodosius, the square denoting the granary known as the "Horrea Lamia" between the Harbor of Theodosius and the Harbor of Julian, and the pins describing the life of various commercial guilds in Constantinople (recovered from the tenth-century Book of the Eparch).

This map should be consulted in combination with the Administrative Regions map.

Religious Life

The traditional description of the Byzantine Empire holds that it "combined" Greek culture, Roman government, and the Christian religion. Scholars have since moved away from these over-simplifications as it is difficult to not think (for instance) of the Christian religion as indelibly both Roman and Greek, not to mention its original form as a Jewish schism or cult. Nevertheless, it is the case that the City of Constantinople was founded as an explicitly Christian city. This statement should not to be taken to exclude the fact that the Christianity (or Christianities) of the city were very different from those that can be witnessed or experienced today, nor from the fact that there were many groups that self-identified as not-Christian whose religious practices also left their own material traces.

This map presents a sampling of the material traces of the imperially-sponsored Christian life and practice of the City of Constantinople. The vast number of churches and monasteries (identified as purple or white blocks with an internal cross) on the base map, and how few of them we have catalogued (as denoted by having a green overlay) show how much work we still have to do simply to present what is already known.

Nevertheless, the little that is here can indicate the variety and liveliness of the Christian practices that animated Constantinople. Readers can recover how a shrine to St. Euphemia sprang up between the Palaces of Antiochos and Lausos to dominate the West side of the great Hippodrome, get just a sniff of the sensory overload that would have characterized an entrance into the cathedral of Hagia Sophia, and click on the extended lines to be reminded of how pervasive regular icon processions became in the later empire.

Water Infrastructure

This map combines imperial water management with private or domestic water management, and the places where the two spheres of Constantinopolitan civic life overlapped.

The larger structures of walls and harbors that allowed Constantinople to survive and thrive while surrounded on three sides by water are demarcated by polygons. Furthermore, the imperially funded constructions of massive cisterns (whether open-air or underground) and aqueducts that sustained a population far exceeding the natural fresh water supply to the area are also so demarcated. Control of these was an imperial interest.

On the other hand, while public baths (here exemplified by the Baths of Zeuxippus near the Hippodrome and the Baths of Constantine near the Church of the Holy Apostles on the Fourth Hill) were imperially funded, they were public spaces in the sense of being devoted to use by private persons.

The mass of individual points (represented by pins) was generated by Christopher Wyckoff from the maps in Crow, Bardill, Bayliss, Bono, and Krausmüller's study The Water Supply of Byzantine Constantinople (2008). Each pin denotes a known location of a private water cistern. Though each case is its own story, in general these may be assumed to have been cisterns built to hold fresh water for a single elite residence. Such cisterns may have been built and maintained by elites, but they should not be assumed to have only been used by elites. They may well have functioned as neighborhood water supplies that could be "tapped" for use by lesser households.

In sum, these cisterns allow us to generate many possible research questions. Do the cisterns give us a functionally accurate picture of elite residence patterns? If so, in particular, what can be made of the significant density of cisterns in the (relatively dry) ancient city on the acropolis point, and the lesser clusters (within the Great Palace, around the Theodosian forum, or around the Church of Christ Pantokrator)? How influential was the Valens Aqueduct in determining suitable living quarters? What is to be made of the persistent pattern of residential settlement along the northern half of the peninsula?

Fall of Constantinople

Perhaps no event has come to symbolize the end of the Middle Ages in the western psyche than the fall of Constantinople to Mehmet the Conqueror in 1453. Although the Byzantine Empire at this point was far from its territorial heyday and ruled little more than Constantinople itself, the loss had a profound emotional toll on Christendom, as the center of Eastern Christianity fell. The fall had profound effects on the city as it would become the capital of the Ottoman Empire, and many of the city’s churches and landmarks were converted into Islamic and Ottoman spaces, such as the Hagia Sophia. The siege itself was notable in its usage of cannons by the Ottomans in bringing down the great Theodosian Walls that had stood for over a thousand years. The destruction of the walls using cannon fire changed military history overnight, rendering the medieval system of castles and fortifications impractical against heavy cannons.

This map highlights the major sights, events, and monuments related to the siege. It offers a combination of historical narration and architectural cataloging in offering a geographic representation of Mehmed’s assault, Constantinople’s defense, and the ultimate fall of the city. The map shows many of the significant fortifications for the defense of the city that had existed since the city’s founding and had been in use throughout its history. The map also conveys the locations and movement of each side’s armies, fleet, and artillery. 

In thinking about the 1453 defenses and ultimate fall of the city, readers will want to compare the impression generated by this information with that generated by the Imperial Presence and Monumental Architecture maps, as the information collected in those places is relevant for imagining the major sights of the city that stood and would have experienced the siege and fall, many of which would be transformed into new Ottoman spaces in the coming centuries.
