Coptic texts form one of the largest groups within the Chester Beatty Papyri Collection.
Coptic is the latest stage of the written form of the Egyptian language. It borrows most of its letters from the Greek alphabet but with the addition of several Coptic letters for sounds not found in the Greek language (inherited from Demotic script).
The majority of the Coptic texts are Christian in subject matter and include biblical manuscripts, homilies and accounts of martyrdoms from the period c. AD 300-800, although there are also some fragments of literary and business documents.
In addition, some of the papyrus manuscripts retain their original bindings, composed of boards of payprus covered with leather on the outside.
