Which philosophy study was Metrodorus of Cos partly addicted to?
Metrodorus of Cos Metrodorus of Cos (Greek: Μητρόδωρος τῆς Κῶ ; fl. c. 460 BC) was the son of Epicharmus. Like several of his family he addicted himself partly to the study of Pythagorean philosophy, partly to the science of medicine. He wrote a treatise upon the works of Epicharmus, in which, on the authority of Epicharmus and Pythagoras himself, he maintained that the Doric was the proper dialect of the Orphic hymns.
Heliodorus (philosopher) Heliodorus (Greek: Ἡλιόδωρος ) is cited as the author of a work titled "Commentary" (dated 564 AD), which has been preserved, on the "Introduction" or "Rudiments" of Paulus Alexandrinus, the 4th century Alexandrian astrologer. The name "Heliodorus" appears only on the later of two groups of manuscripts, and so is somewhat doubtful. Leendert Westerink has argued that the commentary consists of notes of lectures, most likely given by the 6th-century philosopher and astrologer, Olympiodorus, in 564 AD. The Greek text of his commentary on Aristotle's "Nicomachean Ethics" has been published in vol. 19.2 of "Commentaria in Aristotelem Graeca" (CAG).
