A handful of words that we use to talk about wind are variations on names from classical mythology. In Greek legend, Aeolus was the ruler of the winds; he played a key role in Homer’s Odyssey, giving Odysseus a bag containing all of the directional winds except for the west wind to ensure the hero’s safe passage back to Ithaca. Odysseus’s shipmates opened the bag, and the winds blew their boat off course. It follows that the adjective Aeolian means "pertaining to Aeolus, or to the winds in general." Lowercased, aeolian has a more broad meaning of "caused by the wind" or "wind-blown." An aeolian harp is a box with strings tuned in unison that are sounded by the wind.
