Welcome to the site of the database of the Coptic documentary texts of the "Centre de Papyrologie et d'Épigraphie Grecque" of the Université Libre de Bruxelles. This work, started early in 2000 and online since 2005, was conceived on the model of the Heidelberger Gesamtverzeichnis der Griechischen Papyrusurkunden Ägyptens, which had to be adapted to the specificities of the Coptic material. This project is also fully integrated with the Trismegistos platform, which now numbers more than 100 000 records.
The database regroups all the documentary Coptic texts published, i.e. more than 8000 documents. This database is updated periodically. A card is devoted to each text. The information is recorded in the following fields : sigla, inventory number, support, origin, date, dialect, content, bibliography, remarks and Trismegistos number.
