The ancient Greek mystical world was ruled by a small group of gods called the Olympians. When things had to be decided, the council of 12 gods met on Mount Olympus to discuss things. 

All the Olympians kept a home on Mount Olympus. Unless they were off traveling somewhere, that's where you could find most of them. Hades preferred his home in the Underworld. Poseidon preferred his palace under the sea. But the rest of the Olympians lived on Mount Olympus. 

Cadmus was credited by the ancient Greeks. Cadmus was the son of Agenor and the brother of Europa. He was the founder of the city of Thebes. After Zeus kidnapped Europa, Agenor ordered her brothers -- Cadmus, Phoenix, and Cilix -- to search for her, instructing them not to return until they had found her. It was a hopeless quest, and all three brothers became exiles. Phoenix founded the country of Phoenicia, and Cilix established Cilicia. Cadmus consulted the oracle at Delphi and was told to follow a cow that he would find near the oracle; where the cow lay down to rest, he should found a city. He followed the cow to the future site of Thebes. There he instructed his men to bring water so that he could offer a sacrifice to Athena; however, the men encountered a giant serpent which was sacred to Ares, and they were all killed.

Zeus is the ruler of the Olympian gods. He is often seen with a lighting bolt. Zeus, the great presiding deity of the universe, the ruler of heaven and earth, was regarded by the Greeks, first, as the god of all aerial phenomena; secondly, as the personification of the laws of nature; thirdly, as lord of state-life; and fourthly, as the father of gods and men.

Zeus was the god of the sky and ruler of the Olympian gods. Zeus overthrew his Father Cronus.He then drew lots with his brothers Poseidon andHades. Zeus won the draw and became the supreme ruler of the gods. He is lord of the sky, the rain god. His weapon is a thunderbolt which he hurls at those who displease him. He is married to Hera but, is famous for his many affairs. He is also known to punish those that lie or break oaths.
