(Ἀλέξανδρος), commander of the horse in the army of ANTIGONUS DOSON during the war against Cleomenes III. of Sparta. (Plb. 2.66.) He fought against Philopoemen, then a young man, whose prudence and valour forced him to a disadvantageous engagement at Sellasia. (2.68.) This Alexander is probably the same person as the one whom Antigonus, as the guardian of Philip, had appointed commander of Philip's body-guard, and who was calumniated by Apelles. (4.87.) Subsequently he was sent by Philip as ambassador to Thebes, to persecute Megaleas. (5.28.) Polybius states, that at all times he manifested a most extraordinary attachment to his king. (7.12.)
