A Dictionary of Greek and Roman biography and mythology

(Ἄδραστος), of Aphrodisias, a Peripatetic philosopher, who lived in the second century after Christ, the author of a treatise on the arrangement of Aristotle's writings and his system of philosophy, quoted by Simplicius (Praefat. in viii. lib. Phys.), and by Achilles Tatius (p. 82). Some commentaries of his on the Timaeus of Plato are also quoted by Porphyry (p. 270, in Harmonica Ptolemaci), and a treatise on the Categories of Aristotle by Galen. None of these have come down to us; but a work on Harmonics, περὶ Ἁρμονικῶν, is preserved, in MS., in the Vatican Library.
