(Κινέας), a Thessalian, is mentioned by Demosthenes, in a well-known passage (de Cor. p. 324), as one of those who, for the sake of private gain, became the instruments of Philip of Macedon in sapping the independence of their country. Polybius (17.14) censures Demosthenes for bringing so sweeping a charge against a number of distinguished men; but he does not enter specially into the question with respect to Cineas and the Thessalians. (Comp. Dem. de Cor. p. 245, de Checrs. p. 105; Diod. 16.38, 69.)
