Triptolemus-Who

 Triptolemus was a demi-god. He was of the Eleusinian mysteries. "Triptolemus" means "he who pounds the husks." Demeter came to him, mourning the loss of her daughter Persephone to Hades. Demeter instructed Triptolemus in agriculture, and gave to him a winged chariot drawn by serpents, so that he could travel the world spreading agriculture.
