(Ναυσιφάνης), a native of Teos, attached to the philosophy of Democritus, and, according to Sextus Empiricus, a disciple of Pyrrhon. He had a large number of pupils, and was particularly famous as a rhetorician. Epicurus was at one time one of his hearers, and as he could not deny this, though he was anxious to be considered a self-taught man, he was obliged to content himself with abusing him, and maintaining that he had learnt nothing from him. (Cic. de Nat. Deor. 1.26, 33; D. L. 9.69, 102, 10.8, 14; Sext. Empir. ad v. Math. 1.1, p. 215.)
