Antigonus II Gonatas
He was one of those tyrants who were set up at that time in various parts of Greece by the Macedonian king Antigonus II Gonatas. During his tyranny the territory of Megalopolis was invaded by the Spartans under Acrotatus. Pausanias says this was "Acrotatus I, the eldest son of king Cleomenes", but most probably it was Acrotatus II. The army of Megalopolis had the better of the encounter and Acrotatus was killed, which allows to date the battle to c. 262 BC.
