Zeus, king of the gods in Greek mythology

Zeus stands at the heart of the Greek pantheon: king of Olympus, god of the sky and thunder, guarantor of cosmic order and human justice. His name reaches back to the deepest Indo-European layer, where it already designates the personified “bright sky.”

Birth and survival

Son of the Titan Cronus and Rhea, Zeus is born under a dire prophecy: his father, fearing he will be overthrown by his children, swallows each newborn. To save the last, Rhea hides him in a cave on Mount Ida in Crete, where the goat Amalthea nurses him and the Curetes drown his cries by clashing their shields.

The Titanomachy

Grown to adulthood, Zeus frees his swallowed siblings and leads the Olympians in a ten-year cosmic war against the Titans. The full story is told in the Titanomachy. After victory, he divides the world with his brothers Poseidon (the seas) and Hades (the underworld), keeping the sky and supreme sovereignty for himself.

Domains and cult

Zeus is far more than a warrior god: he protects strangers (Zeus Xenios), oaths (Zeus Horkios) and the assembly of the gods. From Mount Olympus, the mountain home of the gods, he wields the thunderbolt forged by the Cyclopes — the ultimate symbol of his sovereignty. His chief sanctuary at Olympia hosted the panhellenic Games in his honor.

His genealogy combines several ancient traditions. With Hera, Zeus fathers Ares and Hephaestus; with Leto, Apollo and Artemis; with Maia, Hermes; with Demeter, Persephone; and with Mnemosyne, the Muses, including Calliope. The Iliad also makes Dione the mother of Aphrodite and presents Zeus as her father, whereas Hesiod tells the competing story of her birth from sea foam.

Among his mortal unions, Semele gives birth to Dionysus, Alcmene to Heracles, and Danae to Perseus. The site’s tree brings these attested lineages together without implying that they all come from one ancient account.
