The Greeks worshipped a pantheon of gods and goddesses, headed by the chief of the gods, Zeus. Other gods included Hera, Zeus’s wife; Athena, goddess of wisdom and learning; Apollo, god of music and culture; Aphrodite, goddess of love; Dionysus, god of wine; Hades, god of the underworld; and Diana, goddess of the hunt.

Greek religion placed little emphasis on ethical conduct – stories about the gods portrayed often them as lying, cheating, being unfaithful, getting drunk and so on. As in many traditional religions, a Greek god or goddess was seen more as a potential source of help, rather than as a focus of devotion.

Each city-state had its own festivals, but certain festivals were common to all the Greeks. The most famous of these were the Olympic games, held in honour of Zeus every four years (starting traditionally in 776 BC). There were much fewer events than in a modern Olympics, and there were competitions in music and poetry as well as in athletics. The winner of an Olympic event was awarded an olive wreath and won great honour in his home city.

The Greeks often consulted oracles – priests or priestesses at certain shrines who, in a trance, uttered messages from the gods. People would go to oracles for advice and guidance on specific matters. The most famous of these was the oracle at the shrine of Apollo at Delphi. Advice was sought by private individuals as well as by politicians and military commanders.

The Greek religion was not something to engage a person’s spirituality, and various cults grew up to fell that void. The Eleusian Mysteries and the cult of Orpheus injected an emotional elements into worship. One joined these through initiation, and their beliefs were secret. Hence we know little about them. However, they stressed the importance of the afterlife – initiates were promised immortality – and the need for ethical standards of behaviour were emphasised.

Numerous myths have come down to us about the Greeks gods, goddesses and semi-divine heroes. They also have much to say about the origins and nature of the world. Many of these myths contradict one another, something that the Greeks found no problem with.
