Olympiodsrus a Neo-Platonic philosopher, was a native of Alexandria, and lived probably in the latter part of the 6th century A.D. There are extant by him commentaries on the First Alcibiades, the Phaedo, the Gorgias, and Philebus of Plato. The first-mentioned of these commentaries contains a life of Plato. His commentary on the Gorgias was published by Routh in his edition of the "Gorgias" and "Euthydemus" (Oxford, 1784); that on the Phaedo by Andreas Mustoxvdes and Demetrius Schinas in the συλλογὴ ἀποσπασματίων ἀνεκδότων (Venice, 1817); that on the Philebus by Stallbaum in his edition of the "Philebus;" and that on the First Alcibiades by Creutzer, in the 2d and 3d volumes of the Initia Philosoph. ac Theolog. ex Platonicis Fontibus (Frankf. 1826). In estimating Olympiodorus from these publications of his, it would appear that he was an acute and vigorous thinker, and a man of great erudition.
