Calas

or CALLAS (Κάλας, Κάλλας).

1. Son of the traitor Harpalus of Elimiotis, and first cousin to Antigonus, king of Asia, held a command in the army which Philip sent into Asia under Parmenion and Attalus, B. C. 336, to further his cause among the Greek cities there. Tn B. C. 335, Calas was defeated in a battle in the Troad by Memnon, the Rhodian, but took refuge in Rhaeteum. (Diod. 16.91, 17.7.) At the battle of the Granicus, B. C. 334, he led the Thessalian cavalry in Alexander's army; and was appointed by him in the same year to the satrapy of the Lesser or Hellespontine Phrygia, to which Paphlagonia was soon after added. (Arr. Anab. i. p. 14e., ii. p. 31d.; Curt. 3.1.24; Diod. 17.17.) After this we do not hear of Calas: it would seem, however, that he died before the treason and flight of his father in 325 [HARPALUS], as we know from Arrian that Demarchus succeeded him in the satrapy of the Hellespontine Phrygia during Alexander's life-time. (See Droysen, Gesck. der Nachf. Alex. p. 68, note 29; Thirlwall's Greece, vol. vii. p. 179, note 2.)
