Greek myth also has it that Nephele is the cloud whom Zeus created in the image of Hera to trick Ixion, since he tried to rape the goddess. Ixion and Nephele gave birth to the Centaurs which were helped by their own mother during their struggle against Heracles.
Nephele married Athamus, but he divorced her for Ino. Phrixus, son of Athamas and Nephele, along with his twin Helle, were hated by their stepmother, Ino. Ino hatched a devious plot to get rid of the twins, roasting all the town's crop seeds so they would not grow. The local farmers, frightened of famine, asked a nearby oracle for assistance. Ino bribed the men sent to the oracle to lie and tell the others that the oracle required the sacrifice of Phrixus. Before he was killed though, Phrixus and Helle were rescued by a flying golden ram sent by Nephele, their natural mother.
Phrixus and Helle were instructed to not look down to earth for the duration of their flight. Helle though, did look down, and fell off the ram into the Hellespont (which was named after her, meaning Sea of Helle) and drowned, but Phrixus survived all the way to Colchis, where King Aeetes took him in and treated him kindly, giving Phrixus his daughter, Chalciope, in marriage. In gratitude, Phrixus gave the king the golden fleece of the ram, which Aeetes hung in a tree in his kingdom. The golden fleece would later be taken by Jason.
