an ancient Greek sculptor, was the son of Micon, and flourished at Aegina in the fifth century B.C. The ascertained facts of his life, as recorded by Pausanias, consist mainly of short notices of his principal works. At Pergamus there was an Apollo; in a sacred cave near Phigalia there was a black Ceres with the horse's head; at Delphi there was a group of statues, the votive offering of the Tarentines; and at Olympia there were a Hercules, a Mercury, a bronze chariot, and a group representing the Grecian heroes drawing lots for the privilege of accepting the challenge of Hector. Onatas also practised painting. He was the assistant of Polygnotus in decorating the vestibule of the temple of Minerva Areia at Platæa, and in this capacity he painted a picture representing the expedition of the Argives against Thebes.
