Abstract
Proclus’ Commentary on Plato’s Timaeus has been preserved in several manuscripts from the IX to the XVI centuries and in a paper scroll of the XI century, Patmos Eileton 897, containing two large parts of Book III (on the world’s body, on the recto, and on the world’s soul, on the verso of the scroll) and a large corpus of scholia vetera to it. This paper aims to examine the two main branches of the tradition of the Commentary and to give some observations on the exegetical apparatus to Proclus in the different forms of scholia figurata (and/or schemata), exegetical scholia, scholia to Proclus.
