(Προμαθίδης), of Heracleia, wrote a work entitled Ἡμίαμβοι, which treated of mythological subjects (Athen. 7.296b.). Besides this work, which must have been in poetry, Promathides also wrote other works in prose, among which was one on the history of his native town. Athenaeus quotes his account of the cup of Nestor (Athen. 11.489b.; Schol. ad Apoll. Rhod. 1.1126, 2.815,847, 913, 931; Steph. Byz. s. v. Γάλλος). Promathides is placed by Passow a little before the time of Augustus. (Vossius, de Hist. Graec. p. 492, ed. Westermann.)
