He was the Greek god of the winds and the king of the floating island of Aeolia. In The Odyssey, Homer claims Aeolus helped Odysseus by giving him a favorable wind. Aeolus also gave English speakers a few terms based on his name, including today's adjective eolian (also spelled aeolian), which is often used for wind-sculpted geological features such as caves and dunes, and aeolian harp, an instrument that makes music when the wind blows across its strings.
