Phaethon is a figure from Greek mythology, known as the son of the sun god Helios. He is famous for his attempt to drive his father's chariot, which carries the sun across the sky. However, he lost control of the horses, leading to chaos and destruction on Earth. To prevent further disaster, Zeus, the king of the gods, struck Phaethon down with a lightning bolt. This act saved the world but resulted in Phaethon's tragic death. His story serves as a cautionary tale about hubris and the consequences of overreaching one's abilities.
