2. A Ruler in Thrace, who inherited in conjunction with Berisades and Cersobleptes the dominions of Cotys, on the death of the latter in B. C. 358. Amadocus was probably a son of Cotys and a brother of the other two princes, though this is not stated by Demosthenes. (Dem. in Aristocr. p. 623, &c.) [CERSOBLEPTES.] Amadocus seems to have had a son of the same name. (Isocr. Philipp. p. 83d. compared with Harpocrat. s. v. Ἀμάδοκος.)
