Aeolus (or Aiolos) in Greek Mythology was the God of the Wind.
He lived on the floating island of Aiolia and was visited by Odysseus and his crew in the Odyssey. He gave hospitality for a month and provided for a west wind to carry them home. Unfortunately he also provided a gift of a bag containing each of the four winds, which Odysseus' crew members opened just before their home was reached. They were blown back to Aiolia, where Aeolus refused to provide any further help.
