An Athenian grammarian, pupil of Aristarchus and Panaetius the Stoic, who lived about 140 B.C. He was a prolific and versatile writer. There is extant under his name a treatise on the gods and the heroic age, entitled Bc(3XtoOiJKn, a valuable authority on ancient mythology. Modern critics are of opinion that, if genuine, it is an abridgment of a larger work by him (IIepi B &w). Edition, with commentary, by Heyne (1803); text by Wagner (1894) ( Mythographi Graeci, vol. i. Teubner series). Amongst other works by him of which only fragments remain, collected in Muller, Fragmenta Historicorum Graecorum, may be mentioned: Xpovuck, a universal history from the fall of Troy to 144 B.C.; H€pe$ynocs, a gazetteer written in iambics; Hope Necuv, a work on the Homeric catalogue of ships; and a work on etymology (' ETVµoAoyiac).
