Jason was the leader of the Argonauts . Jason was the son of the lawful king of Iolcus, but his uncle Pelias had usurped the throne. Pelias lived in constant fear of losing what he had taken so unjustly. He kept Jason's father a prisoner and would certainly have murdered Jason at birth. But Jason's mother deceived Pelias by mourning as if Jason had died. Meanwhile the infant was bundled off to the wilderness cave of Chiron the Centaur . Chiron tutored Jason in the lore of plants, the hunt and the civilized arts. When he had come of age, Jason set out like a proper hero to claim his rightful throne. Unknowingly, Jason was to play his part in a plan hatched on lofty Mount Olympus . Hera , wife of almighty Zeus himself, nursed a rage against King Pelias. For Jason's uncle, the usurper king, had honored all the gods but Hera. Rashly had he begrudged the Queen of Heaven her due. Hera's plan was fraught with danger; it would require a true hero. To test Jason's mettle, she contrived it that he came to a raging torrent on his way to Iolcus. Before giving Jason the throne, Pelias gave Jason the task of retrieving the Golden Fleece .
To get the Golden Fleece, Jason assembled the Argonauts , a band of pirates ready for the task. As they sailed they encountered numerous obstacles, such as Talos , Harpies guarding the blind prophet Phileas , the Hydra , and the living skeletons. In the end, Jason won the throne and fell in love.
