Now, having told you that bit of truth, I will go back to what the Greeks thought.  They said that Deucalion had a son whose name was Hellên, and that he again had three sons, called Æolus, Dorus, and Xuthus.  Æolus was the father of the Æolian Greeks, and some in after times thought that he was the same with the god called Æolus, who was thought to live in the Lipari Islands; and these keep guard over the spirits of the winds—Boreas, the rough, lively north wind; Auster, the rainy south wind; Eurus, the bitter east; and Zephyr, the gentle west.  He kept them in a cave, and let one out according to the way the wind was wanted to blow, or if there was to be a storm he sent out two at once to struggle, and fight, and roar together, and lash up Neptune’s world, the sea.  The Æolians did chiefly live in the islands and at Corinth.  One of the sons of Æolus turned out very badly, and cheated Jupiter.  His name was Sisyphus, and he was punished in Tartarus—Pluto’s world below—by having always to roll a stone up a mountain so steep that it was sure to come down upon him again.
