The Onomasticon of Iudaea • Palaestina and Arabia in the Greek and Latin Sources (henceforth: Onomasticon) is a comprehensive collection of Greek and Latin texts from the Hellenistic, Roman and Byzantine periods that mention individual names of settlements, geographical entities (such as regions, mountains and rivers), administrative units (names of provinces and
districts) and ethnic names (nations, tribes and clans) within the geographical and chronological limits of the research. It was initiated by the late Prof. Michael Avi-Yonah (1904–1974), and carried out for decades by Prof. Yoram Tsafrir (who passed away in 2016), and by Dr. Leah Di Segni, who serves now as the sole academic director and Principal Investigator (PI) of the project. So far (as for March 2018), two volumes already appeared in print: Vol. I, dedicated to the major texts, and Vol. II.1&2, dedicated to toponyms that start with the letter A.  
The Digital Application was set up in early 2018. Its objectives are to serve as a platform for insertion all data, to enable efficient communication between the PI and her assistants and ease regular inspection on their work. In due course it will present all the data to the public via the internet in a user-friendly manner. The application is operative at present for editorial work and “guest view” at

In the Home page the following documents from Vol. I are accessible: Introduction, Preface, Sigla and Abbreviations, Titles and TOC, Bibliographical Abbreviations and the Primary Sources – to which Vol. I, published two years ago, was dedicated. Vol. II, dedicated to sites starting with the Letter A, was published a month ago as Vol. II; Vol. III., dedicated to Letter B, is under
final stages of work before its submission to the print-house. Work on the Sacred Sites (the next volume) and on Letters C-Z is now (March 2018) digital.
A double-click on the Sacred Sites button, or on those marked by the letters C-Z, opens a list of all Sacred Sites (, 861 altogether, including cross-references) or the regular, non-sacred sites, starting with that particular letter, as published in Vol. I and updated since then (see, for Letter C:, holding 206 sites). All this information, including the amount of sites in each site-category, is available now to the viewer. For editorial purposes, the list of sites presents also checkboxes indicating the editorial state of each site:
Bibliography inserted, Discussion done and All done.

In accord with the structure of the hard copies (Vols. I and II), two templates were devised for insertion and presentation of data: Site Card and Text Card. Two views modes are available: View and Edit. An edit mode opens a Site Card or a Text Card for editorial purposes. A view mode enables passive inspection of the data that was already inserted.

The Site Card template includes the following windows:
Toponyme name
Site definition / cross reference
Sacred site (checkbox)
Comment on the Toponym

A double click on a particular site opens a list of all references to texts associated with it (all these references, except for Jerusalem, are available now as MS Word documents; their upload to the application requires a certain procedure). See, for example, for the Cathisma:, holding 7 references; and for Caesarea:

The amount of listed texts is provided at the heading of the list, according to their category: Primary texts (707 in the case of Caesarea); Inscriptions (4 in the case of Caesarea); Supplementary texts (313 in the case of Caesarea); and Coins. The numbering, all trough, is consecutive. The list of references also includes check-boxes (see below), enabling to get, at glance, the editorial state of each Text Card.
A double-click on a reference opens a Text Card in which the site name and the text title appear automatically. The text card has the following windows for the insertion and presentation of data:

  • Introductory note
  • Text Window
  • Apparatus
  • Translation
  • Comment on text

These windows are followed by the following control buttons:

  • Greek / Latin text first inserted
  • Greek / Latin text approved
  • English translation inserted
  • Comment on text inserted
  • All done

Search Command
This was devised in order to enable easy navigation and retrieval of data. Three search options
are available: According to Toponym – either regular or sacred site; text caption and any word.
