Zeus is the Greek god of the sky, thunder, and lightning, as well as the king of all gods in Greek mythology. He is the son of the Titan Cronus and Rhea, and brother to Poseidon, Hades, Hera, Demeter, and Hestia. Zeus overthrew his father, Cronus, and led a successful rebellion against the Titans, ultimately establishing a new order of gods called the Olympians. As the supreme deity of the Olympian gods, Zeus ruled over Mount Olympus and was associated with law, order, justice, and the moral conduct of both gods and humans. He was considered the father of many of the Greek heroes and mythical figures, including Heracles, Perseus, and Athena. Zeus is commonly depicted as a powerful, bearded man wielding a lightning bolt, symbolizing his dominion over the sky and his immense power.
