Classical Greek religious beliefs were polytheistic and focused on rituals rather than specific beliefs or doctrines. Many gods and goddesses were worshipped, including Gaia, Artemis, Aphrodite, Apollo, Demeter, Persephone, and Dionysus. Important religious sites included temples like the Temple of Artemis at Ephesus and the Delphi Oracle of Apollo. Mystery religions such as the Eleusinian Mysteries honored Demeter and Persephone. Theater and drama also had religious aspects, with plays performed in honor of Dionysus and depictions of myths and legends.
