(Εὐθυκράτης), a Greek statuary, whom Pliny places at Ol. 120, B. C. 300. (34.8. s. 19.) He was the most distinguished son and pupil of Lysippus, whom he imitated more in his diligence than in his gracefulness, preferring severe truth to elegance of expression. (Plin. l.c. § 7.) This feature of his style was seen in a most excellent statue of Hercules, at Delphi, and in his statues of Alexander, the hunter Thestis, and the Thestiadae: the rest of the passage, in which Pliny enumerates his works, is hopelessly corrupt. (See Sillig, Catal. Artif. s. v.) According to Tatian, Euthycrates made statues of courtezans. (Orat. in Graec. 52 p. 114, ed. Worth.)
