Golden Fleece

From LitWiki

The legend of Golden Fleece originated on the wild coast of Thessaly. There a Zeus existed who demanded the sacrifice of young boys. One of these victims, the Greek Phrixus, whom his stepmother Ino wanted to sacrifice.Phrixus was saved through the help of Chrysomallus, the winged golden ram, on whose back Phrixus escaped with his sister Helle across the Black Sea. Helle fell into the sea, known by her name Hellespont, but Phrixus reached Colchis, where he was taken in by king Aeetes. In gratitude Phrixus gave the king the ram’s fleece and Aeetes set a dragon to guard it.
