The Olympian Gods

The Olympian gods were the main gods of Ancient Greece. After defeating their ancestors, the Titans, the Olympian gods became the rulers of the world (cosmos) and represented the civilization of the world. The Olympian gods dwelt majestically and democratically on Mount Olympus, the highest mountain in Greece, which was built by the Cyclopes. The leader of the Olympian gods was Zeus.

The gods were born and grew up like men- some of them even married, but they did not age and death never came to them. They lived in human-like bodies with an ethereal fluid called ichor flowing through their veins. They had passions and human weaknesses and were often in the wrong, but then had to take full responsibility for their actions
The Greek myths always speak of the twelve gods of Mount Olympus, but in fact there were altogether more Olympian Gods in Greek Mythology. However, there were never more than twelve at one time. The four alternative gods were Hestia, Hades, Dionysus and Demeter, depending on the location.
