(Ἀλκέτας), king of EPIRUS, was the son of Tharypus. For some reason or other, which we are not informed of, he was expelled from his kingdom, and took refuge with the elder Dionysius, tyrant of Syracuse, by whom he was reinstated. After his restoration we find him the ally of the Athenians, and of Jason, the Tagus of Thessaly. In B. C. 373, he appeared at Athens with Jason, for the purpose of defending Timotheus, who, through their influence, was acquitted. On his death the kingdom, which till then had been governed by one king, was divided between his two sons, Neoptolemus and Arybbas or Arymbas. Diodorus (19.88) calls him Arybils. (Paus. 1.11.3; Dem. Timoth. pp. 1187, 1190 ; Diod. 15.13. 36.)
