Aeacus. Aeacus was a mythological king of the island of Aegina in the Saronic Gulf.
   Aeacus was the son of Zeus by Aegina, a daughter of the river-god Asopus, and thus, brother of Damocrateia. In some accounts, his mother was Europa and thus possible brother to Minos, Rhadamanthus and Sarpedon.
   He was the father of Peleus, Telamon and Phocus and was the grandfather of the Trojan war warriors Achilles and Telemonian Ajax. In some accounts, Aeacus had a daughter called Alcimache who bore Medon to Oileus of Locris.
   Aeacus' sons Peleus and Telamon were jealous of Phocus and killed him. When Aeacus learned about the murder, he exiled Peleus and Telamon.
   Aeacus was born on the island of Oenone or Oenopia, where Aegina had been carried by Zeus to secure her from the anger of her parents; afterward, this island became known as Aegina. Some traditions related that, at the time when Aeacus was born, Aegina was not yet inhabited, and that Zeus either changed the ants of the island into the men over whom Aeacus ruled, or he made the men grow up out of the earth. Ovid, on the other hand, supposed that the island was not uninhabited at the time of the birth of Aeacus, instead stating that during the reign of Aeacus, Hera, jealous of Aegina, ravaged the island bearing the name of the latter by sending a plague or a fearful dragon into it, by which nearly all its inhabitants were carried off.
