Extensively annotated critical texts of Theophilus Protospatharius, Leo the Physician, Constantinus Pogonatos (De cibis; On foods). Digital facsimile from Google Books at this link.

Leo the Physician was a medical encyclopedist; traditionally dated to 9th century, but possibly as late as 12th–13th century CE. His Epitome survives in only one manuscript, possibly because Leo avoided theological discussions and streamlined his text for students who were probably learning medicine in the hospitals of Constantinople.
