Phrixus
A son of Athamas, king of Thebes, and Nephele. On the plea of insanity, Nephele was repudiated by Athamas, who then married Ino, who persecuted Phrixus with inveterate hatred, because he was to succeed to the throne in preference to one of her own children. Being apprised that Ino had designs on his life, he started with his sister Helle to go to Aeetes, king of Colchis.
According to the poets they mounted on a ram, whose fleece was gold, which soared into the air, directing its course to Colchis. Helle became giddy, and, falling into the sea (afterward called the Hellespont), was drowned. Phrixus arrived at the court of Aeetes, whose daughter Chalciope he married. Some time afterward he was killed by his father-in-law..
The murder of Phrixus gave rise to the famous Argonautic expedition under Jason, the object being to recover the Golden Fleece, which Jason succeeded in obtaining.
