Alexander (Gr. Ἀλέξανδρος) was commander of the cavalry in the army of Antigonus III Doson during the war against Cleomenes III of Sparta.[1][2] He fought against Philopoemen, then a young man, whose prudence and valor forced him to a disadvantageous engagement at Sellasia.[3] This Alexander is probably the same person as the one whom Antigonus, as the guardian of Philip (son of Demetrius II of Macedon), had appointed commander of Philip's body-guard, and who was slandered by Apelles.[4] Subsequently he was sent by Philip as ambassador to Thebes, to persecute the Macedonian Megaleas.[5] Polybius states that at all times he manifested a most extraordinary attachment to his king.[6]
