The present paper proposes an account of my research on human and veterinary medicine in Graeco-Roman and Byzantine Egypt, undertaken since 2008 at the CEDOPAL at the University of Liège. This research focuses on literary papyri, particularly on the Anonymus Londiniensis (Hermopolis?, 2d half of the Ist century A.D.), the longest known Greek medical papyrus, as well as on documentary fragments, far more numerous than their literary counterparts, of which several categories have been studied in my PhD dissertation defended in Liège in March 2015.
