About the Census
What is the Census?
The Census of Antique Works of Art and Architecture Known in the Renaissance began in 1946 as an idea emerging in correspondence between Richard Krautheimer in New York and Fritz Saxl in London. Today, it is connected to the Department of Art and Visual History at Humboldt-Universität zu Berlin. The project is currently led by Kathleen Christian, Professor of Early Modern Art History, and a staff of postdocs and student assistants.
The Census database is an online collection of ancient monuments (such as sculptures, coins, reliefs, architectural structures) and of texts and images from the post-classical era that respond to this antique material culture. The two primary categories of records are “Antique Monument” and “Postclassical Work.” With regard to postclassical works, the focus lies on works created between 1400 and 1600.
The Census is a central resource for researchers and for anyone interested in topics of classical reception and the afterlife of antiquity Since its inception, the project has assembled a vast collection of images and bibliographic references, at first using index cards and photographs. Already in the early 1980s the Census was then digitized, and it is now accessible in the form of an online database.
More information about the history of the Census database is gathered in an online exhibition on the topic.
What is the significance of the Census project and Census database for researchers?
In 1946, when Richard Krautheimer and Fritz Saxl first formulated the idea of the Census, their goal was to replace a “lack of specific information regarding the antique material accessible to Renaissance scholars and artists” with a precise catalogue of literary and pictorial sources referring to or describing antique works of art extant in the Renaissance. When the project began, it followed a methodological approach that had been prevalent since the nineteenth century in the sphere of classical archaeology: this was the method major figures such as Rodolfo Lanciani or Christian Hülsen had used to catalogue Renaissance sketchbooks and put Renaissance drawings in one-to-one relationships with antique works of art. While this method gave shape to the Census project and its cataloguing system, in current scholarship representations of and creative responses to antiquities are understood in more diverse and subtle ways. Archaeologists and art historians are aware that postclassical texts and works of art present in the Census can scarcely be reduced to the status of “documents” of the appearance, location or condition of antiquities.
As research about the reception of antiquity expands, the Census still remains a precious resource that extends beyond its original aims. It is a tool that allows researchers to probe a topic of crucial importance: the antiquities that fascinated Early Modern artists, humanists and patrons and inspired an extraordinary variety of new inventions. The Census is, indeed, one of the best tools for working with material legacy of antiquity in the Early Modern era, a visual culture which now largely been lost with the dispersal of collections and the movement of objects into modern-day museums. Decades of painstaking research that gave shape to the Census database make it one of the best resources researchers can use to access vanished, yet extraordinarily significant material contexts for the Early Modern reception and reinterpretation of antiquity.
As a longstanding project that has engaged major institutional partners over its lifetime (including NYU, the Warburg Institute, the Getty and the Hertziana), the Census is intertwined with the history of these institutions, and with the history of the disciplines of archaeology and art history. The Census was one of the first art-historical collections to be digitized (in the early 1980s), and the project has bridged many decades of technological change, from the analogue, to the digital, to the internet ages.
Aligned with the latest standards and technologies of digital humanities, particularly through its membership in CORDH (Consortium for Open Research Data in the Humanities), the Census now aims to take a leading role in developing new digital methods for sharing and analysing humanities data. The database itself aims to represent the subtleties of a complex field using an open and expandable resource. For a more detailed discussion of these recent changes, see the “Linked Open Data” FAQs below.
What data can be found in the Census database?
The category “Antique Monuments” is primarily concerned with ancient statues, buildings and coins, but also includes inscriptions, mosaics, and paintings.
The category “Postclassical Works” is mostly related to prints, drawings, and texts such as guidebooks. Other types of Postclassical Works include paintings, medals, bronze statuettes as well as inventories of collections. Most of these works were created in Western Europe, particularly Italy, between the years 1400 and 1600.
The other object types in the database (Person, Bibliography, Style, Period, Location, and Image) provide supplementary information about Antique Monuments and Postclassical Works.
Primarily, the information in the Census database reconstructs relationships between Antique Monuments and Postclassical Works. The classic example is a juxtaposition of the antique Apollo Belvedere now in the Vatican with a drawing of this statue in the sixteenth-century Cambridge Sketchbook. Thousands of similar relationships linking works of antique art and architecture with Early Modern artistic representations and textual descriptions of antiquities are traced by the Census database. These relationships map instances of the reception of antique material culture as well as the history of the postclassical survival of antique ruins and remains. Within the provenance histories that are found in the records for Antique Monuments, one can follow the collecting histories of ancient statues, inscriptions and other antique art works.
The Census project was in its first decades primarily concerned with the period 1400–1530 and with textual descriptions of antiquities and drawings after antique sculpture. In the 1980s, it expanded to encompass the period 1400–1600 and to include the reception of antique architecture.
In addition to the records concerning these core topic of the Census database, collaborating projects have also added records that relate to earlier and later historical periods. Between c. 2009–2015, records related to medieval works of art were entered into the database in cooperation with the project Corpus Medii Aevi.
Between c. 2009–2016, records related to the reception of antiquity by Johann Joachim Winckelmann and other antiquarians of his time were added by the project Corpus Winckelmann.
Recently, the Census database has expanded to include material contributed by the project Jacopo Strada’s Magnum ac Novum Opus: A Sixteenth-Century Numismatic Corpus. Between 2015 and 2022, drawings of Strada’s Magnum ac novum opus and the antique coins related to these were added to the Census.
Currently, work is underway to expand the Census database with records contributed by the project Historical Memory, Antiquarian Culture, Artistic Patronage: Social Identities in the Centres of Southern Italy, which is concerned with antiquities in Southern Italy during the Early Modern era.
When searching the Census database, users can use the advanced search or the filter to search by “Contributing Project’ to show records added by:
HistArtAntSI: Historical Memory, Antiquarian Culture, Artistic Patronage: Social Identities in the Centres of Southern Italy
Strada: Jacopo Strada’s Magnum ac Novum Opus: A Sixteenth-Century Numismatic Corpus
Can I add my data to the Census database?
Partner projects have contributed to the Census over the years and greatly expanded the contents of the database. In the new software system launched in March, 2023, data added by these projects has become easier to identify. It is possible, for example, to search for data contributed by the project “Jacopo Stradas Magnum ac Novum Opus: Ein numismatisches Corpus des 16. Jahrhunderts” by using the filter, or by using the advanced search tool to search for “Contributing Project”→“Strada”.
Please get in touch (census [dot] ikb [at] hu-berlin [dot] de) if you are interested in adding data from a related project to the Census database.
What is new?
What is different about the new interface?
The search functions have changed significantly: while users of the previous version of the database first had to choose between “Antique Monuments” and “Post-Antique Documents” when making search queries, the new interface now has a free-text bar which allows them to search the entirety of database entries.
Within the new interface, the vast image collection of the Census takes center stage. Users can view search results as images of multiple objects and artworks, and no longer have to open records one-by-one to access images.
As was the case in the previous version, the user account function enables the creation of personal collections, in which users can save records for future reference. In the new database, however, whenever copyright allows it is also possible to download relevant images. In the future the Census will also be adding PDFs of bibliographic literature or other files which, when out of copyright, will be available for download.
Another change in the new interface is that the object type previously referred to as “Post-Antique Documents” is now called “Postclassical Works.” The new terminology reflects the complexity of post-classical texts and works of art themselves, as well as the complexity of their relationships with antique material culture. The means of transmission between the physical remains of antiquity and post-classical works of art are far from straightforward. These relationships are no longer defined in the Census database through the framework of “documentation,” allowing users to grapple instead with the subtle ways in which Postclassical texts and images relate to or respond to the antique.
In the new interface, records more clearly indicate uncertainty about dates, locations, and authorship. There is also greater opportunity to model in the database varied opinions about these topics. New fields in the data model can define the era in which opinions about the dates, authors and locations of antique monuments originated: in the Early Modern period, or in current scholarship. These features allow the Census database to model diverse opinions about objects and texts that might have been considered antique in the Early Modern era, but are not considered antique in current scholarship.
The Census database has also been semantically modelled, and other Linked Open Data features that are being introduced and implemented (see the FAQs below).
At the moment the map view, which was available as part of the old database interface, is currently not available.
How to Use the Database
How do I search the Census database?
There are many ways to search the database using the free text search bar, the Advanced Search function, and filters. Some methods tend to work better for different types of searches (for example, when searching for text, or when searching for images). Please see below for techniques, tips, and recommendations.
1. SOURCES
SOURCES: Next to the free search bar is a button labelled ‘Sources.” Here one can select the object types one wishes to search. Users can search for these object types, singly or in combination. It is recommended, however, that users keep only the object types “Antique Monument” and “Postclassical Work” checked, then use the filters or the Advanced Search to narrow down the results. Although it may seem intuitive to search for “Image,” this category only contains information about image files. Searching for both Antique Monuments and Postclassical Works allows users to find all images in the database, as well as all information regarding bibliography, period, style, person and location.
Underneath the object types is a pool called “Census” which contains all the records of the Census database. Make sure this box is always checked, otherwise the contents of the database cannot be searched.
2. SEARCH BAR
SEARCH BAR: Type keywords directly into the search bar to generate results. By default, when two search terms are entered in the full-text search bar, they are linked by the operator “AND,” so that both terms must therefore be present in the resulting records.
You can use the operators AND, NOT, OR and parentheses for more complex combinations of search terms.
Examples of free text searches:
#219823: inserting a CensusID in the search bar, with the # sign before the number, brings up the record identified by this CensusID, the Vatican Laocoön.
Aspertini + sarcophagus : this search brings up results in which the terms “Aspertini” and “sarcophagus” are both present.
Aspertini sarcophagus: this search yields the same results as Aspertini + sarcophagus
“Hercules Farnese:” since there are quotation marks around the a two-word phrase, the results that appear will be relevant to the statue of Hercules Farnese in Naples, rather than all records related both to Hercules and to the Farnese.
(Zuccari Laocoon) — Getty: this search brings up CensusID #10005521, a drawing in the Uffizi by Federico Zuccari of his brother Taddeo drawing the Laocoon in the Belvedere. A similar drawing of this subject in the J. Paul Getty Museum (Census ID #10003642) is not included in the results (note that entering the minus symbol in the search bar should produce the word NOT).
We recommend searching for one or two terms and then using the filters or Advanced Search to narrow down your results. For users who already have very specific information they wish to search for (such as an inventory number), starting with the Advanced Search may be the most convenient option (see below).
Important tip: the names of cities in the Census are not translated into English but are kept in local languages. Thus if you are searching for a work of art in Naples, type “Napoli” in the search bar. Users may get better results by using the Advanced Search, or by narrowing down results by location using the filters.
3. FILTER
FILTER: You can use the filters visible on the left-hand side of the screen to narrow down search results.
While searching Antique Monuments and Postclassical Works for “sarcophagus” in the search bar results in thousands of records, these can be filtered, for example, by selecting only Antique Monuments or Postclassical Works. You can continue to narrow down the search results, for example by activating the “Current Location” filter until you find a particular city or museum. Filtering by “Creation / Actors Involved in Creation / Actor” narrows down the results to works by a particular artists or author, for example Amico Aspertini or Ulisse Aldrovandi.
4. ADVANCED SEARCH
Advanced Search provides a comprehensive and exact tool for searching the Census database. Advanced Search allows you to search by selecting fields that are already present in the database, and allows you to specify that search terms must appear in specified fields. It is therefore a more efficient and effective way of searching than by typing keywords in the free-text search bar.
You can open the Advanced Search window by clicking on the small button located on the right-hand side of the search bar:
You can then search “All object types” or specific object types, depending on which object types are selected in the “Sources” menu:
In the Advanced Search window, you can enter a CensusID directly, and here there is no need to enter the hastag (#) before the number. You can also enter a UUID (Universally Unique Identifier).
In “All Object Types” mode, you can narrow the search for an Antique Monument to records identified as ‘Main Antique Monuments,” that is, objects or buildings that are not parts of other monuments. Opening up “Linked Object Types,” underneath, you can limit the search by Contributing Project, or other fields.
In Advanced Search, we recommend selecting either “Antique Monument” or “Postclassical Work” in the upper left-hand corner of the window:
The parameters you set in Advanced Search will appear in the search bar after you press the button “Apply to Search.” There, these search parameters can be further combined with keywords. For example, you can use the Advanced Search to limit the results to a particular Contributing Project, then type in the word “Nero” in the search bar.
Under Parent entry, you can narrow down or expand your search results based on the place of these results in the structure of the Census data:
Keeping in mind the hierarchical structure of the Census data in mind, you can select the following search criteria:
All without subordinate level: selects only the lowest level of the hierarchy, such as the parts of a page or the parts of a column.
All with subordinate level: selects all records that are superordinate to other records. These are not necessarily the top-level entries in the hierarchy.
All without superordinate level: selects only the top-level level of the hierarchy, such as the Pantheon or the Codex Coburgensis.
All with superordinate level: selects all records that are subordinate to other records. These records are not necessarily the lowest-level entries in the hierarchy.
The check box for “all without superordinate level” is particularly useful in narrowing down searches of complex Antique Monuments or Postclassical Works (such as the Pantheon or the Codex Coburgensis). Checking this box helps you find your way quickly to the top-level record, which might otherwise be lost in results containing numerous subordinated records.
In an advanced search of Antique Monuments, you can insert keywords in numerous fields: these include inventory number (under “Identifiers”), class, type, descriptive details, date of creation, preservation history (including restorations), or provenance history. You can also search for Antique Monuments by Postclassical Works related to them, or by the bibliography that refers to them.
In an advanced search for Postclassical Works, you can search by date of creation, actors involved in creation (such as artists or authors), or medium. You can also search for Postclassical Works by the Antique Monuments related to them in the Census database, or by bibliographic references.
Tip: A useful feature of Advanced Search is that it offers a convenient way of searching Postclassical Works for text strings. Using the “Transcription” field of the Postclassical Work object type you can search, for example, for a passage in the manuscripts of Pirro Ligorio:
5. VIEW:
VIEW: Once you have narrowed down your search, select a view to examine the results. You can have your results appear in three different types of views.
Standard View prioritizes images and is best for viewing works of art:
Table View includes all fields organized in a row and is recommended for advanced users only:
You can adjust the settings for all three of these types of views by clicking on the button with three dots, for example if you would like to see up to 1,000 records at a time. In these settings, it is recommended to keep the button “Flat hierarchy” selected. If it is not selected, the results you are not be able to view records on the lowest level of the Census data’s hierarchical structure (see the FAQ on hierarchy and above under “advanced search” for more information):
6. DETAIL VIEW:
Once you have found a single record that you would like to explore, you are ready to examine it in “detail view.” Please see the FAQ about understanding detail views for further information (What data is available in the “Postclassical Work” records? and What data is available in the “Antique Monument” records?)
What is the “Advanced Search” function on the right-hand side of the search bar?
See above, “How do I search the Census database,” at point 4.
How do I use the “Filter” function underneath the search bar?
See above, “How do I search the Census database,” at point 3.
How can I search for a whole phrase instead of just single words?
To only receive results that contain multiple words in a specific order, put the desired phrase in quotation marks. For example, if you tick Antique Monument as the option under Sources and enter “Hercules Farnese” in the searchbar, you will only receive the sculpture known under that name instead of all entries that contain either “Hercules” and “Farnese.”
What are CensusIDs and how can I use them to search the database?
CensusIDs are unique identifiers attached to every record in the Census database. When referencing the database, please cite the relevant CensusID.
To search the database for a particular CensusID, type a # sign followed by the number directly in the searchbar (i.e. #12345). Note that the search will not work without the “#” sign. Another method for finding a record using a CensusID is to click on the “Advanced Search” button on the right of the search bar:
Enter the CensusID in the appropriate field. Do not use the “#” sign in this search field:
Why is the hierarchical structure of the data important in the search functions of the database?
Many records in the Census database are organised according to a hierarchical tree structure, so that certain top-level entries (the Pantheon, the Codex Coburgensis, or Ulisse Aldrovandi’s guidebook to Rome) contain within them subordinate entries: the columns of the Pantheon are subordinate to the Pantheon, and the parts of these columns are in turn subordinate to the columns themselves. The individual pages of the Codex Coburgensis are subordinate to the Codex as a whole, while specific parts of pages are subordinate to whole pages.
The coffers of the ceiling of the Pantheon are thus modelled in this fashion:
When one searches the database, the default settings will provide maximum search results, with the expectation that researchers should start with an overview of all records related to a particular search, then use the filters or orient themselves within the database’s hierarchical structure to find the desired records.
It is important to note that the page numbers of particular bibliographic references are modelled as records that are subordinate to a full and complete bibliographic reference. When you select a record that only includes page numbers, such as “pp. 1–10” and you must orient yourself within the hierarchy to find the bibliographic reference itself at the top level. Make sure that the “Show hierarchy” button is selected and that the panel showing hierarchical structure, on the left side of the Detail view, is visible. You will find therefore the record for “Augustus 003” underneath a volume of Roman Imperial Coinage, which is itself modelled underneath the top-level entry for Roman Imperial Coinage, where you will find full bibliographic information:
>
How to narrow down search results using the hierarchical structure:
Using views: Under the search bar, users will find the filter followed by buttons which can be used to select three different types of views: the standard view which prioritises images, the text view and the table view. For each of these views, users can either select or deselect the button “flat hierarchy” accessible by clicking on the three dots to the right of the view setting buttons (see image below). When hierarchy is flattened by selecting this button, all levels of data, from the top of the tree to the bottom, are visible at once. If flat hierarchy is deselected, viewers see the upper level of a hierarchy (records which have other records subordinated to them).
Using Advanced Search: In Advanced Search under Parent entry, you can choose from four options to narrow down or expand your results:
All without subordinate level: selects only the lowest level of the hierarchy, such as the parts of a page or the parts of a column.
All with subordinate level: selects all records that are superordinate to other records. These are not necessarily the top-level entries in the hierarchy.
All without superordinate level: selects only the top-level level of the hierarchy, such as the Pantheon or the Codex Coburgensis.
All with superordinate level: selects all records that are subordinate to other records. These records are not necessarily the lowest-level entries in the hierarchy.
The check box for “all without superordinate level” is particularly useful in narrowing down searches of complex Antique Monuments or Postclassical Works (such as the Pantheon or the Codex Coburgensis). Checking this box helps you find your way quickly to the top-level record, which might otherwise be lost in results containing numerous subordinated records.
How can I zoom in on images and download them?
In Detail view, you can access all images associated with a specific record. The image preview at the top of the record entry can be shown or hidden by clicking “Show/Hide Image Preview” in the top left of the image preview window, as is shown here:
On the top right of the image preview window are three further buttons:
Images with green ticks marked as “Available for Download” can be downloaded in different sizes, including a full-size version. Click the first button in the row, “Download”.
To open full-screen view, click the second button in the row, “Open full-screen view.” Here you can view the image in its full resolution and can zoom in. You can also scroll through the gallery to see other images displayed in the current search.
The third button with three dots provides a shortcut to new searches based on the data in the record you are viewing. Here you can also access the record’s “Change History” where you can find information on the history of the record itself.
What data is available in the “Antique Monuments” records?
The “Antique Monument” and “Postclassical Work” records contain the core data of the Census database.
Antique Monuments:
Taking the top-level entry for the Pantheon as an example, one sees the hierarchical structure of the data shown in the left-hand column: the Pantheon is the top-level entry and is subdivided into many parts.
On the right column, images are shown on the top. You can see on the bottom left-hand corner of the image preview window that there are 18 images linked to these records; these can be viewed by clicking on the arrows in this box. For more about viewing images, see the FAQ for “How can I zoom in on images and download them?”
The heading includes the primary name of the monument, the object type (“Antique Monument”) followed by the CensusID.
The Pantheon is classified as a Main Antique Monument.

What data is available in the “Postclassical Works” records?
The “Antique Monument” and “Postclassical Work” records contain the core data of the Census database.
Postclassical Work:
Taking the top-level entry for the Codex Coburgensis as an example, one sees the hierarchical structure of the data shown in the left-hand column: the Codex itself is the top-level entry and is subdivided into parts.
On the right column, images are shown on the top. You can see on the bottom left-hand corner of the image preview window that there are 2 images linked to this record; these can be viewed by clicking on the arrows in this box. For more about viewing images, see the FAQ for “How can I zoom in on images and download them?”

User Accounts and Personal Collections
Am I required to create a personal account to use the database?
No, those without an account can use the database as well. However, some functions are only accessible once an account has been registered, i.e. saving searches and collections. A new account can be registered by writing to census [dot] ikb [at] hu-berlin [dot] de.
What are collections and how do I use them?
Collections offer the possibility to save certain results of a search in order to be able to access them directly at a later time:
Users’ personal collections are listed in the Quick Access column. You can open this column by clicking on the arrow icon to the left of “Search.”
There are two ways to create a new collection:
-
New collections can be created by right-clicking on a search result; the selected record will be added to it
-
In the Quick Access column, you can add or remove a new collection by clicking on + or — in the footer.
By right-clicking on a collection, it can be renamed, copied, or deleted.
In SAVED SEARCHES, you can also save a search: click after your search on the button with three dots on the upper right-hand corner and select SAVE.
How do I add records to a collection?
To add a new object to a collection, it can be dragged and dropped from the results view to the specific collection in the Quick Access menu. Entries can also be re-sorted and moved within different collections using drag and drop. Right-click to delete individual items from a collection.
Language and Copyright
In which languages is the database available?
The interface and the database content are only available in English. Transcriptions of written sources are, however, always given in the original language, as are also the names of cities and regions, i.e. the database uses “Roma” instead of “Rome.”
How do I cite the records in the Census database?
When referring to records in the database, please quote the CensusID, the URL including the CensusID, and the date of access. For example: CensusID 10187294, https://database.census.de/detail/10236645 (1 April 2023),
Which copyrights apply to the image material in the Census?
Images that are tagged with green checkmarks and are free of copyright restrictions are downloadable and made freely available to users.
All other images may be viewed inside the Census database but cannot be copied, reproduced or reused by users. Users can find the sources of these images in the image record as well as copyright information. Unfortunately, the Census cannot provide images to users that are not tagged with the green “available for download” checkmark.
Linked Open Data (FAQs in English only)
Does the Census data follow the FAIR principles (i.e., is the data findable, accessible, interoperable and reusable?)
The process of making the Census data FAIR, to the fullest extent that copyright allows, is nearly complete.
In 2021–23, the data was transformed into semantic RDF data in collaboration with Takin.solutions (George Bruseker and Denitsa Nenova). This transformation will enable the regular export of data from the Census database to a repository where it can be searched or re-used by other researchers. In the repository, the Census data will be available as semantic data modeled according to the CDOC-CRM framework, in particular to the framework of the SARI data models developed by the Swiss Art Research Infrastructure. The process of modeling Census data according to this recognised framework (developed specifically for art historical data) and its export to a repository where it can be searched and re-used will transform the Census data into FAIR data, since for the first time it will be not only findable and accessible but also interoperable and reuseable. In the repository, researchers can also query the Census data using SPARQL, the query language of the semantic web.
We expect this repository to be available in the near future.
Most of the images in the Census database are governed by copyright laws and images will not be available on the new repository. Images are however made available for download directly from the database when copyright allows. Please refer to the image tag (the green checkmark) for information concerning the copyright of downloadable images.
It is expected that in the future bilbiography will also be made available when copyright allows.
Has the Census data been modelled according to the CIDOC-CRM?
In 2021–2023, George Bruseker and Denitsa Nenova of Takin.solutions modelled the Census data with the semantic framework used most often for cultural heritage data, the CIDOC-CRM. More specifically, they aligned the Census data with reference data models created by Swiss Art Research Infrastructure (SARI) in Zurich. The goal of this project was to create linked, open Census data and new possibilities for searching, finding and using this data.
Bruseker and Nenova’s documentation of the Census Semantic Data Models (CSDM) can be found here and an introduction to the data models can be found here on the Census website.
In the last phase of the project, which is expected to be completed soon, Census semantic data will be exported to a repository where it can be searched using SPARQL queries, or re-used.
Is it possible to search Census data using SPARQL queries?
This feature is currently being developed and will be available soon.
Does the Census database use IIIF?
IIIF has been enabled technically in the database and is planned to be released in the near future.
Other than CensusIDs, which identifiers does the database reference?
Census records have been partially linked to identifers from the following indices:
VIAF – Virtual International Authority File
GND – Gemeinsame Normdatei, Deutsche Nationalbibliothek
iDAI,gazetteer – Place names defined by the Deutsches Archäologisches Institut
Pleiades – Place names defined by the Pleiades gazetteer
TGN – Getty Thesaurus of Geographic Names
ULAN – Getty Union List of Artist Names
Geonomes — Geographical database
Wikidata – Open knowledge base
Norm data are currently being developed and expanded.
Where can I learn more about the transformation of the Census data into Linked Open Data and semantic data?
The process of transformation, as well as information about the CIDOC-CRM models adopted by the Census, has been fully documented.
