A poetic or archaic term referring to Aeolus, the Greek god of winds, or anything associated with wind.
Directly from Greek 'Aiolos', the god of the four winds in Greek mythology. The name has been used in English since the Renaissance to refer both to the mythological figure and to wind-related phenomena.
The ancient Greeks literally personified wind as a god because they couldn't see it but could feel its massive effects—imagine how mysterious that must have seemed before anyone understood air pressure!
