This Greek myth is told in Hesiod’s Theogony and Homeric Hymn 28. Zeus’ first wife was Metis, goddess of wisdom. Warned by Gaia and Uranus that the son she would bear would surpass his father, Zeus swallowed her while she was pregnant. In time Athena was born from Zeus’ head; the Homeric Hymn sings that as she leapt out in gleaming golden armour, brandishing a spear, Olympus shook and the sea surged.
Pindar and later writers add that the smith god Hephaestus (or Prometheus) split Zeus’ head with an axe. Athena became goddess of wisdom and war, weaving and crafts, and patron of Athens; her birth was carved on the east pediment of the Parthenon.
