Greek Mythology

The 12 Olympian Gods

Who ruled what, what their symbols meant, and the myths every Greek child grew up hearing.

The short answer

Greek mythology centres on twelve Olympian gods led by Zeus, who ruled from Mount Olympus after overthrowing the Titans. Each god governed a domain — the sea, war, love, wisdom, the harvest — and interacted constantly with mortals, producing the heroes and monsters of the best-known myths.

The 12 Olympian gods

Each Olympian ruled a domain of life and carried recognisable symbols in art. Their Roman name is given in brackets.

  1. 1
    Zeus (Jupiter)
    Sky, thunder, kingship

    King of the gods and enforcer of oaths and hospitality. Symbols: thunderbolt, eagle, oak. He overthrew his father Cronus and divided the cosmos with his brothers.

  2. 2
    Hera (Juno)
    Marriage, family

    Queen of the gods and Zeus's wife and sister. Symbols: peacock, pomegranate, diadem. Many myths follow her retribution against Zeus's lovers and their children.

  3. 3
    Poseidon (Neptune)
    Sea, earthquakes, horses

    Ruler of the sea, known as the 'earth-shaker'. Symbols: trident, dolphin, horse. He lost the contest for Athens to Athena and pursued Odysseus across the Mediterranean.

  4. 4
    Demeter (Ceres)
    Harvest, grain

    Goddess of agriculture and the seasons. Symbols: wheat sheaf, torch. Her grief when Hades took her daughter Persephone explains the barren months of winter.

  5. 5
    Athena (Minerva)
    Wisdom, strategy, craft

    Born fully armed from Zeus's head, patron of Athens and of skilled work. Symbols: owl, olive tree, aegis. The Parthenon was built in her honour.

  6. 6
    Apollo
    Light, music, prophecy, healing

    God of the lyre, of archery and of the oracle at Delphi. Symbols: lyre, laurel wreath, bow. Twin brother of Artemis and one of the few gods the Romans did not rename.

  7. 7
    Artemis (Diana)
    Hunt, wilderness, the moon

    Protector of wild animals and of young girls, and a sworn virgin goddess. Symbols: bow, deer, crescent moon. Her temple at Ephesus was a wonder of the ancient world.

  8. 8
    Ares (Mars)
    War, courage, violence

    The brutal, chaotic side of war, in contrast to Athena's disciplined strategy. Symbols: spear, helmet, vulture. Greek myth treats him with far less respect than Rome later did.

  9. 9
    Aphrodite (Venus)
    Love, beauty, desire

    Born from sea foam near Cyprus. Symbols: dove, rose, myrtle, seashell. Her award of the golden apple to Paris set the Trojan War in motion.

  10. 10
    Hephaestus (Vulcan)
    Fire, metalworking, craftsmanship

    The smith of the gods, who forged Achilles' armour and Zeus's thunderbolts. Symbols: hammer, anvil, tongs. The only Olympian described as physically disabled.

  11. 11
    Hermes (Mercury)
    Travel, trade, messages, thieves

    Messenger of the gods and guide of souls to the underworld. Symbols: winged sandals, caduceus, winged cap. Famous as a trickster from the day he was born.

  12. 12
    Hestia / Dionysus
    Hearth / wine and theatre

    Hestia guarded the hearth and the sacred flame of the household. In later lists she gives up her seat to Dionysus, god of wine, ecstasy and drama, whose festivals gave rise to Greek theatre.

Heroes, monsters and myths to know

  1. Heracles (Hercules)

    Son of Zeus and the strongest of the heroes, sentenced to twelve near-impossible labours including the Nemean Lion, the Hydra and the capture of Cerberus.

  2. Odysseus

    King of Ithaca whose ten-year journey home from Troy — Cyclops, Sirens, Circe, Scylla and Charybdis — is told in Homer's Odyssey.

  3. Theseus and the Minotaur

    The Athenian hero who entered the Cretan labyrinth, killed the bull-headed Minotaur, and found his way out using Ariadne's thread.

  4. Perseus and Medusa

    Perseus beheaded the gorgon Medusa, whose gaze turned people to stone, using a polished shield to avoid looking at her directly.

  5. Prometheus

    The Titan who stole fire from the gods and gave it to humanity, and was chained to a rock as punishment where an eagle ate his liver daily.

  6. Pandora

    The first woman, given a sealed jar (later called a box) that released every evil into the world, leaving only hope inside.

Common questions

Who are the 12 Olympian gods?
The twelve Olympians are Zeus, Hera, Poseidon, Demeter, Athena, Apollo, Artemis, Ares, Aphrodite, Hephaestus, Hermes and either Hestia or Dionysus, depending on the source. They were believed to live on Mount Olympus and rule the mortal world from there.
Who is the most powerful Greek god?
Zeus, king of the gods and ruler of the sky, is the most powerful Olympian. His brothers Poseidon (sea) and Hades (underworld) are close in strength, but Zeus holds authority over both gods and mortals.
What is the difference between Greek and Roman gods?
The Romans adopted Greek gods and renamed them: Zeus became Jupiter, Hera became Juno, Poseidon became Neptune, Aphrodite became Venus and Ares became Mars. The myths are largely shared, though Roman versions often emphasise duty and the state over personality.
Who are the three main Greek gods?
Zeus, Poseidon and Hades — the three sons of Cronus who divided the universe after overthrowing the Titans. Zeus took the sky, Poseidon the sea and Hades the underworld, while the earth was shared.
Is Hades one of the 12 Olympians?
No. Hades rules the underworld and does not live on Mount Olympus, so he is traditionally excluded from the twelve, even though he is one of the most important gods in Greek mythology.
What are the most famous Greek myths?
The best known are the Twelve Labours of Heracles, the Trojan War and the Odyssey, Theseus and the Minotaur, Perseus and Medusa, Prometheus stealing fire, Pandora's box, Icarus flying too close to the sun, and the abduction of Persephone.
