Many of the ancient Greek people recognized the major (Olympian) gods and goddesses (Zeus, Poseidon, Hades, Apollo, Artemis, Aphrodite, Ares, Dionysus, Hephaestus, Athena, Hermes, Demeter, Hestia, and Hera), although philosophies such as Stoicism and some forms of Platonism used language that seems to posit a transcendent single deity.
Different cities often worshiped the same deities, sometimes with epithets that distinguished them and specified their local nature.
