When Aeolus blew into town, things really got moving. 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.
