Phaethon  (´e-thon )—lit. “the shining” (Gr.).—Son of the sungod (Apollo) and Clymene (klī´men-ē). Having obtained permission from his father to drive the chariot of the sun across the heavens for one day, he drove so near the earth that he almost set it on fire, his strength being insufficient to keep the horses in the right track. Consequently Jupiter hurled him down with a thunderbolt into the river Padus (Po).
