(Ἀνταγόρας), of Rhodes, a Greek epic poet who flourished about the year B. C. 270. He was a friend of Antigonus Gonatas and a contemporary of Aratus. (Paus. 1.2.3 ; Plut. Apophth. p. 182, E, Sympos. iv. p. 668, C.) He is said to have been very fond of good living, respecting which Plutarch and Athenaeus (viii. p. 340, &c.) relate some facetious anecdotes. Antagoras wrote an epic poem entitled (Θηβαΐς, Vita Arati, pp. 444, 446, ed. Buhle.) This poem he is said to have read to the Boeotians, to whom it appeared so tedious that they could not abstain from yawning. (Apostol. Proverb. Cent. 5.82; Maxim. Confess. ii. p. 580, ed. Combefisius.) He also composed some epigrams of which specimens are still extant. (D. L. 4.26 ; Anthol. Graec. 9.147.)
