We don’t do a lot with inscriptions here. But I wonder if people realise that there are inscriptions in Coptic? I certainly never thought about this; but there are.
Anthony Alcock has made a text and English translation of three stone stelae, which have Coptic inscriptions. These are from various locations around Egypt.
(I’ve asked Dr A. for the reference for the original publication – will add it later).
The editor, Claudius Labib, was a Copt who sought to revive Coptic as a spoken language in his country, and with much success. His publication is in Arabic and French. The Coptist blog has a bibliography, with links to many of his works.
