De Caelo.

Syria'nus

(Συριανός) a Greek philosopher of the Neo-Platonic school, 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 tinder Plutarchus, the Head of the Neo-Platonic school, who regarded him with great admiration and affection, and appointed him as his successor. The most distinguished of his disciples was Proclus, who regarded him with the greatest veneration, and gave directions that at his death he should be buried in the same tomb with Syrianus.

Works

Suidas attributes to Syrianus the following writings :-- 1. Εἰς ὅμηρον ὅλον ὑπό- μνημα, in 7 books.2. Εἰς τὴν Πολιτείαν Πλάτωνος, in 4 books.3. Εἰς τὴν Ὀρφέως Θεολογίαν, in 2 books.4. Εἰς τὰ Πρόκλου περὶ τῶν παῤ Ὁμήρῳ Θεῶν.5. Συμφωνίαν Ὀρφέως Πυθαγόρου καὶ Πλάτωνος.6. Περὶ τὰ λόγια, in 10 book.7. Various other works of an exegetical character. There is, however, a good deal of difficulty about this list. The very same series of works is assigned by Suidas himself to Proclus (s. v. Προκλ.), and we can hardly suppose that Syrianus wrote a commentary on a work of his successor, as Suidas states.

On the other hand, Suidas makes no mention of works which we find Syrianus stated by other authorities to have written, or even of works by him which are still extant. No reliance whatever, ever, therefore, can be placed on the list of Suidas.

Commentaries on Aristotle

Syrianus wrote commentaries on various parts of Aristotle's writings.

1. On the books De Caelo.

2. On the book De Iaterpretatione.

A commentary on the Timaeus

From various references in the commentary of Proclus on the Timaeus of Plato, we learn that Syrianus also wrote a commentary on the same book, as well as συμφωνίας γράμματα, answering to the work of the same kind mentioned in the list of Stuidas.

Commentaries on the Magna Syntaxis of Ptolemaeus

Theodorus Meliteniotes, in his Prooemium Astronomiam (printed in Fabricius, Bibl. Gr. vol. x. pp. 401, &c.), mentions commentaries on the Magna Syntaxis of Ptolemaeus, by the philosopher Syrianus (l.c. p. 406).

Commentaries on the Metaphysics

The most valuable remains that we possess. however, 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 word 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 specting it must be false. (In Met. ii. fol. 13, b.) On the whole, the doctrines laid down in this work are those of the Neo-Platonic school generally.
