Syrianus ( _el. Συριανός) 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, 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 Syrianus.


Only a little remains of the writings of Syrianus, the surviving works are:
*A Commentary on Aristotle's "Metaphysics".
*Commentaries on two rhetorical works by Hermogenes.
*Lectures on Plato's "Phaedrus", preserved by Hermias.

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. [Suda, "Proklos".]


The most valuable remains that we possess are the commentaries on the "Metaphysics" of Aristotle. In explaining the propositions of Aristotle, he appends the views held by his school on the subject in hand, and endeavours to establish the latter against the former. One of his fundamental principles is, that it is a proposition of general applicability, that the same cannot be both affirmed and denied at the same time of the same thing; but that in any sense involving the truth of either the affirmation or the denial of a proposition, it applies only to existing things, but not to that which transcends speech and knowledge, for this admits neither of affirmation nor of denial, since every assertion respecting it must be false. [Syrianus, "In Met." ii. fol. 13, b.] On the whole, the doctrines laid down in this work are those of the Neoplatonist school.
