According to some authors he was a pupil of Anaxagoras, and also of Damon, as Alexander states in his Successions of Philosophers. When Anaxagoras was condemned, he became a pupil of Archelaus the physicist; Aristoxenus asserts that Archelaus was very fond of him. Duris makes him out to have been a slave and to have been employed on stonework, and the draped figures of the Graces on the Acropolis have by some been attributed to him. Hence the passage in Timon’s SilliFr. 25 d.: From these diverged the sculptor, a prater about laws, the enchanter of Greece, inventor of subtle arguments, the sneerer who mocked at fine speeches, half-Attic in his mock humility.
