Twelve Olympians
Greek deities varied locally, but many shared panhellenic themes, celebrated similar festivals, rites, and ritual grammar. The most important deities in the Greek pantheon were the Twelve Olympians: Zeus, Hera, Poseidon, Athena, Apollo, Artemis, Aphrodite, Hermes, Demeter, Dionysus, Hephaestus, and Ares. Other important Greek deities included Hestia, Hades and Heracles. These deities later inspired the "Dii Consentes" galaxy of Roman deities.
