Alcetas
(Ἀλκέτας), whose age is unknown, was the author of a work on the offerings (ἀναθήματα) in Delphi, of which Athenaeus quotes the second book. (xiii. p. 591c.)
(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.) [C.P.M]
II., king of Epirus, was the son of Arymbas, and grandson of Alcctas I. On account of his ungovernable temper, he was banished by his father, who appointed his younger son, Aeacides, to succeed him. On the death of Aeacides, who was killed in a battle fought with Cassander B. C. 313, the Epirots recalled Alcetas. Cassander sent an army against hint under the command of Lyciscus, but soon after entered into an alliance with him (B. C. 312). The Epirots, incensed at the outrages of Alcetas, rose against him and put him to death, together with his two sons; on which Pyrrhus, the son of Aeacides, was placed upon the throne by his protector Glaucias, king of the Illyrians, B. C. 307. (Paus. 1.11.5; Diod. 19.88, 89 ; Plut. Pyrrh. 3.) [C.P.M]
(Ἀλκέτας), the eighth king of Macedsonia, counting from Caranus, and the fifth, counting from Perdiccas, reigned, according to Eusebius, twenty-nine years. He was the father of Amyntas I., who reigned in the latter part of the sixth century B. C. (Hdt. 8.139.)
(Ἀλκέτας), the brother of Perdiccas and son of Orontes, is first mentioned as one of Alexander's generals in his Indian expedition. (Arrian, 4.27.) On the death of Alexander, he espoused his brother's party, and, at his orders, murdered in B. C. 322 Cyane, the half-sister of Alexander the Great, when she wished to marry her daughter Eurydice to Philip Arrhidaeus. (Dioed. 19.52; Polyaen. 8.60; Arrian, apud Phot. p. 70, ed. Bekker.) At the time of Perdiccas' murder in Egypt in 321, Alcetas was with Eumenes in Asia Minor engaged against Crateris; and the army of Perdiccas, which had revolted from him and joined Ptolemy, condemned Alcetas and all the partizans of his brother to death. The war against Alcetas, who had now left Eumenes and united his forces with those of Attalus, was entrusted to Antigonus. Alcetas and Attalus were defeated in Pisidia in 320, and Alcetas retreated to Termessus. He was surrendered by the elder inhabituants to Antigonus, and, to avoid falling into his hands alive, slew himself. (Diod. 18.29, 37, 44_46; Justin, 13.6, 8; Arrian, apud Phot. l.c.)
