Adrastus of Aphrodisias

Adrastus of Aphrodisias (Greek: Ἄδραστος ὁ Ἀφροδισιεύς; fl. 2nd century) was a Peripatetic philosopher who lived in the first half of the 2nd century AD.^[1]

He was the author of a treatise on the arrangement of Aristotle's writings and his system of philosophy which was quoted by Simplicius,^[2] and by Achilles Tatius.^{[page needed]} Some commentaries of his on the Timaeus of Plato are also quoted by Porphyry,^[3] which was also used by Theon of Smyrna in the surviving sections of his On Mathematics Useful for the Understanding of Plato.^[1][4] and a treatise on the Categories of Aristotle by Galen.^{[page needed][5]}

None of these works have survived.^[5] In some medieval manuscripts, a work with the title Harmonica was attributed to Adrastus, however, this was a misattribution of a work by Manuel Bryennios.^{[6][7] [8][9]}
