 The Byzantine tradition is primarily relevant for the textual transmission of Simplicius’ works. From the little that is known, Byzantine scholars seem to have had a special interest in the Commentary on the Physics. One of the most important manuscripts conserving this commentary (Mosquensis Muz. 3649), not used by Hermann Diels in his CAG edition, was copied by the Byzantine princess Theodora Palaiologina Rhaulaina (ca. 1240–1300; see Harlfinger 1987). Simplicius’ Commentary on the Physics was used by Michael Psellus, Nicophorus Blemmydes (in his Isagogical Epitome; Golitsis 2007), Georgios Pachymeres (in his own Commentary on the Physics, traditionally attributed to Psellus; Golitsis 2008b), Georgios Gemistius-Plethon, Georgios Scholarius, and Theodorus of Gaza. Since there was a lively debate among Byzantine philosophers on the relation between Plato and Aristotle, it is very likely that Simplicius had an impact in this respect.
