Olympiodorus the Younger

Among the extant writings of Olympiodorus the Younger are a biography of Plato, commentaries on several dialogues of Plato and on Aristotle, and an introduction to Aristotelian philosophy. Olympiodorus also provides information on the work of the earlier Neoplatonist Iamblichus which is not found elsewhere. The surviving works are: • Commentary on Plato's Alcibiades (Σχόλια εἰς τὸν Πλάτωνος Ἀλκιβιάδην) • Commentary on Plato's Gorgias (Σχόλια σὺν θεῷ εἰς τὸν Γοργίαν) • Commentary on Plato's Phaedo (Σχόλια εἰς τὸν Πλάτωνος Φαίδωνα) • Life of Plato (Βίος Πλάτωνος) • Introduction (Prolegomena) to Aristotle's Logic (Εἰς τὰ προλεγόμενα τῆς Λογικῆς) • Commentary on Aristotle's Meteorology (Εἰς τὸ πρῶτον τῶν Μετεωρολογικῶν Ἀριστοτέλους σχόλια) • Commentary on Aristotle's Categories (Σχόλια εἰς τὰς Ἀριστοτέλους Κατηγορίας) • Commentary on Aristotle's On Interpretation (Σχόλια εἰς τὸ Ἀριστοτέλους Περὶ Ἑρμηνείας) • A polemical work against Strato. In addition, a Commentary by Olympiodorus is extant on Paulus Alexandrinus' Introduction to astrology (which was written in 378 AD). Although the manuscript of the Commentary is credited in two later versions to a Heliodorus, L. G. Westerink argues that it is actually the outline of a series of lectures given by Olympiodorus in Alexandria between May and July 564 AD. The Commentary is an informative expatiation of Paulus' tersely written text, elaborating on practices and sources. The Commentary also illuminates the developments in astrological theory in the 200 years after Paulus.
