The ancient Greeks had gods, temples and rituals, but no word for religion
Greek worship had no scripture, no creed and no central priesthood. What mattered was doing the rituals correctly, not believing the right things. Even gods sharing a name could differ wildly: Sparta's Artemis was a virgin huntress, while the Artemis of Ephesus was a many-breasted fertility goddess.
The Greeks lacked any term matching the modern idea of a religion, and no ancient writer sorted their gods into separate faiths. Herodotus described Greek identity partly as shared shrines, sacrifices and customs. Scholars now speak of closely related religious dialects rather than one system, because authority was purely local: priests were often city magistrates, some festivals were run by particular families, and Pausanias records a child priest at Tegea's temple of Athena Alea, replaced once he reached puberty.
Most Greeks honoured twelve Olympians, with Zeus as king but not almighty. The gods were immortal yet neither wholly good nor all-powerful, bound by fate: Odysseus was destined to reach Ithaca, so the gods could only delay him. They quarrelled, took sides in the Trojan War and fathered demigods with mortals. Cities adopted patrons, Athena at Athens and Aphrodite at Corinth, and worship spread from Ionia to Sicily and colonies such as Massalia, later shaping Etruscan and Roman religion.
Honoured texts existed without being scripture. Homer and Hesiod carried authority, often opening with a plea to the Muses, yet Plato wanted myths banned from his ideal state for their low morals. Hesiod's Theogony offers one creation story, beginning with Chaos and moving through Gaia and the Titans to the Olympians, but no single account was official. Only mystery cults, such as the Orphics, treated certain writings as canonical within their circles.
Ideas about death shifted over time. Early on all the dead went to Hades; mystery cults of the Archaic age added Tartarus for the damned and Elysium for the virtuous. Pythagoras and Plato entertained reincarnation, and Epicurus taught that the soul dissolves into atoms. Rituals took place at altars standing outside temples, where worshippers left offerings, poured wine, and sacrificed animals, eating most of the meat and burning the rest. Moderation was prized, and hubris was even a crime in Athens.
