Zeus was the youngest son of the Titans, Cronus and Rhea. According to the myths, he was the sky and thunder God, who ruled as king of the Gods of Mount Olympus. After the defeat of Cronus, the world was divided between his three sons; Zeus was given the sky, Hades the underworld, and Poseidon the sea, with the earth and Mount Olympus belonging to all three. He is often presented as a wise older man with a beard and is usually represented by symbols such as the lightning bolt and the eagle. He was married to Hera and was father of several Greek Gods and heroes, such as Hercules and Athena.
