You remember that Cadmus founded Thebes.  One of his daughters was named Ino.  She married a son of King Æolus, who had been married before, and had two children, Phryxus and Helle.  Ino was a cruel stepmother, and deceived her husband into thinking that the oracle at Delphi required him to sacrifice his son to Jupiter; but as the poor boy stood before the altar, down from the skies came a ram with a golden fleece, which took both the children on his back, and flew away with them over land and sea; but poor Helle let go in passing the narrow strait between Asia and Europe, fell into the sea, and was drowned.  The strait was called after her, the Hellespont, or Helle’s Sea.  Phryxus came safely to Colchis, on the Black Sea, and was kindly received by Æetes, the king of the country. They sacrificed the golden-woolled ram to Jupiter, and nailed up its fleece to a tree in the grove of Mars.
