ABSTRACT
Theophilus is one of the least accessible authors in the Greek Patrology because so much of his oeuvre is fragmentary or preserved only in Latin, Coptic, Armenian, Syriac or Arabic versions.1 To study him, as Marcel Richard has remarked, one needs to have a whole library at one’s disposal.2 Excerpts from his letters were included in the florilegia that played an important part in the Christological controversies of the fifth, sixth and seventh centuries, as well as in other works. But his writings were not handed down as a corpus in the Byzantine manuscript tradition.
