In Greek mythology, Aeolus (; Ancient Greek: , Aiolos [aolos], Modern Greek: ['e.o.los] "quick-moving, nimble") was the keeper of the winds and king of the island of Aeolia, one of the abrupt rocky Lipara islands close to Sicily. Later classical writers regarded him as a god.
Aeolus was the son of Hippotes, son of Mimas, a son of Aeolus, son of Hellen. He was most frequently conflated with Aeolus, the son of Poseidon, god of the sea. According to some accounts, Hippotes married the same Melanippe who was the mother of Arne.
Like Aeolus, the son of Poseidon, this Aeolus was said to have had twelve children - six sons and six daughters. According to Diodorus, he was father of six sons by Cyane, daughter of Liparus (the eponym of the island Lipara, whom Aeolus assisted in conquering lands above Surrentum, Italy). The sons' names were Agathyrnus, Astyochus, Androcles, Iocastus, Pheraemon, Xuthus, whereas the daughters are not mentioned at all. The sons were said to have become kings: Iocastus of the region in southern Italy as far as Rhegium; Pheraemon and Androcles of the part of Sicily between the Strait of Messina and Lilybaeum; Xuthus of Leontini; Agathyrnus of what was known as Agathyrnitis, having founded Agathyrnum; and Astyochus of Lipara. All were said to have been remembered as just and pious rulers.
Another list of Aeolus' children is found in scholia on the Odyssey. The latter source gives the sons' names as Androcles, Chrysippus, Iocastus, Phalacrus, Pheraemon, Xuthus, and the daughters' as Aeole, Astycrateia, Dia, Hephaestia, Iphthe, Periboea; their mother in this account is Telepora or Telepatra, daughter of Laestrygon.
This Aeolus lived on the floating island of Aeolia and was visited by Odysseus and his crew in the Odyssey. After their misadventure in Polyphemus' cave, Aeolus gave them hospitality for a month and provided them a west wind to carry them home to Ithaca. He also provided a gift of an ox-hide bag containing all winds but the west. Odysseus and his crew members traveled steadily and anxiously for several days, but with his native land in sight, Odysseus sank overpowered by sleep. His men proceeded to indulge their curiosity to see the costly presents which they thought the bag contained, opened it unwittingly, and out burst the imprisoned winds with such a roar that the force drove the ship back to Aeolus' island. Aeolus refused to provide any further help, because he believed that their short and unsuccessful voyage meant that the gods did not favour them. This Aeolus was perceived by post-Homeric authors as a god, rather than as a mortal and simple Keeper of the Winds (as in the Odyssey).
