Syrianus

Syrianus (Ancient Greek: Συριανός, Syrianos; died c. 437) was a Greek Neoplatonist philosopher, and head of Plato's Academy in Athens, succeeding his teacher Plutarch of Athens in 431/432. He is important as the teacher of Proclus, and, like Plutarch and Proclus, as a commentator on Plato and Aristotle. His best-known extant work is a commentary on the Metaphysics of Aristotle. He is said to have written also on the De Caelo and the De Interpretatione of Aristotle and on Plato's Timaeus.

He was a native of Alexandria, Egypt and the son of Philoxenus. We know little of his personal history, but that he came to Athens, and studied with great zeal under Plutarch of Athens, the head of the Neoplatonist school, who regarded him with great admiration and affection, and appointed him as his successor. He is important as the teacher of Proclus and Hermias. Proclus regarded him with the greatest veneration, and gave directions that at his death he should be buried in the same tomb with Themistius.

Only a little remains of the writings of Syrianus, the surviving works are:

Among the lost works, Syrianus wrote commentaries on Aristotle's De Caelo and De Interpretatione. We learn from the commentary of Proclus on the Timaeus of Plato that Syrianus also wrote a commentary on the same book. Syrianus also wrote works on The Theology of Orpheus, and On the Harmony of Orpheus, Pythagoras and Plato with the Oracles. Theodorus Meliteniota, in his Prooemium in Astronomiam, mentions commentaries on the Magna Syntaxis of Ptolemy by the philosopher Syrianus. The Suda attributes several works to Syrianus, but which are in fact the works of Proclus.
