Legendary: known from narrative tradition, not the historical record

This group holds the deities of ancient Greek religion, among the best documented pantheons of the ancient world thanks to a rich literary record from Homer and Hesiod onward. At its centre are the twelve Olympians (Zeus, Hera, Poseidon, Athena, Apollo, Artemis, Aphrodite, Ares, Hephaestus, Hermes, Demeter and either Hestia or Dionysus), who dwell on Mount Olympus and govern the ordered cosmos.

Around them the browser will find the older generation of Titans they overthrew, primordial powers such as Gaia and Chronos, chthonic and underworld figures led by Hades and Persephone, and a wide company of lesser gods, nymphs and personifications.

Greek religion was practised through local cult, festival and sacrifice for well over a thousand years; the myths preserved in poetry and drama are one part of it, the civic and mystery cults another. The same god could be worshipped under many local titles and take a different character from city to city.

The tradition was later absorbed and renamed by Rome, and its gods became the common vocabulary of Western art and letters long after the temples closed. The entries note both the classical Greek figure and its Roman counterpart where the two were identified.
