Abstract

Galen’s commentary on the Hippocratic Aphorisms is transmitted by a large amount of Medieval and Renaissance manuscripts. Some of them remarkably display a “mixed” text, in which Galen’s commentary is combined with passages from the later commentator Theophilus. Most important among these is the Marc. gr. V 9 (coll. 1017), which inserts two large passages by Theophilus into the Galenic commentary (i. e. VI 1-38; VII 12-73). Both of them were copied by the late physician and student of John Argyropoulos in Constantinople, Demetrios Angelos, who was not primarly involved in the production, but purchased the manuscript after completion and restored its text using another commentary on the Aphorisms, which he had at his disposal. This paper aims at investigating codicological, paleographical and philological aspects of the Marc. gr. V 9, in order to retrace the origin of its mixed commentary and place it in its historical-cultural context.
