According to Roman Mythology the Twelve Olympian gods gained their supremacy in the world of gods after Jupiter led his brothers to victory in war with the Titans. The Titans were the children of Earth and Heaven who sprang from Chaos, the mother of the Titans. The Titans consisted of six sons and six daughters, the one-hundred-armed giants (Hecatonchires) and the one-eyed giants, the Cyclopes.

The Mythology surrounding the Olympian Gods
According to mythology the home of the gods was on the summit of Mount Olympus, in Thessaly. A gate of clouds opened to permit the passage of the Roman gods to earth, and to receive the gods on their return. The Olympian gods had their separate dwellings but all, when summoned, went to the palace of Jupiter on Mount Olympus, as did also those deities whose usual abode was the earth, the sea or the underworld. It was also in the great hall of the palace of the Jupiter the king of the gods where the Olympian gods feasted each day on ambrosia and nectar, their food and drink. It was in the palace on Mount Olympus that the Olympian gods and goddesses discussed the affairs of heaven and earth. As they feasted upon their nectar, Apollo, the god of music, delighted the Roman gods with the tones of his lyre, to which the muses sang in responsive strains. When the sun was set, the Olympian gods retired to sleep in their respective dwellings on Mount Olympus.
