Miscellanies 1.21.131

Indeed, Onomacritus of Athens, whose are said to be the poems attributed to Orpheus, is found in the time of the rule of the Pisistratids, about the fiftieth Olympiad; Orpheus, who sailed with Heracles, was the teacher of Musaeus; Amphion precedes the Trojan War by two generations; Demodocus and Phemius were famous for playing the cithara after the capture of Ilium (the one among the Phaeacians, the other among the suitors). And they say that the oracles attributed to Musaeus are by Onomacritus, the Crater of Orpheus by Zopyrus of Heraclea, and the Descent to Hades by Prodicus of Samos. Ion of Chios in his Triagmi relates that Pythagoras too attributed some works to Orpheus. Epigenes, in his work on the poetry attributed to Orpheus, says the Descent to Hades and the Sacred Discourse are by Cercops the Pythagorean, and the Robe and the Physics by Brontinus. Some also make Terpander ancient; Hellanicus relates that he lived in the time of Midas, and Phanias, putting Lesches of Lesbos before Terpander, makes Terpander younger than Archilochus, and says Lesches competed with Arctinus and won. Xanthus the Lydian says that Thasos was founded about the eighteenth Olympiad (Dionysius says about the fifteenth), so that it is clear that Archilochus was already known after the twentieth Olympiad. He mentions the destruction of the Magnesians as recent. Simonides is placed in the time of Archilochus, and Callinus not much earlier; for Archilochus mentions the Magnesians as destroyed, Callinus as prospering. Eumelus of Corinth, being older, overlapped with Archias, the founder of Syracuse.
