Greek and Roman religion encompasses the collection of beliefs and rituals practiced in ancient Greece and ancient Rome in the form of both popular public religion and cult practices. These different groups varied enough so that one might speak of Greek or Roman religions or "cults", though most shared similarities.
Many Greek people recognized the 14 major gods and goddesses: Zeus, Hera, Poseidon, Apollo, Artemis, Aphrodite, Ares, Dionysus, Hephaestus, Athena, Hermes, Demeter, Hestia, and Hades though philosophical religions such as Stoicism and forms of Platonism posited a transcendent single deity. Different cities worshipped different deities, sometimes with epithets that specified their local nature. The Roman gods were essentially the same with variations in certain names.
