Aeolus (/iːˈoʊləs/; Ancient Greek: Αἴολος, Aiolos [a͜ɪ́olos], Modern Greek: [ˈe.o.los]), a name shared by three mythical characters, was the ruler of the winds in Greek mythology. These three personages are often difficult to tell apart, and even the ancient mythographers appear to have been perplexed about which Aeolus was which. Diodorus Siculus made an attempt to define each of these three (although it is clear that he also became muddled), and his opinion is followed here.
