Twelve Olympians
The principal gods of the ancient Greek religion were the Dodekatheon, or the "Twelve Gods", who lived on the top of Mount Olympus. The most important of all ancient Greek gods was Zeus, the king of the gods, who was married to his sister, Hera. The other Greek gods that made up the Twelve Olympians were Ares, Poseidon, Athena, Demeter, Dionysus, Apollo, Artemis, Aphrodite, Hephaestus, and Hermes. Apart from these twelve gods, Greeks also had a variety of other mystical beliefs, such as nymphs and other magical creatures.
