In Greek mythology, Metis ("wisdom" or "wise counsel") was a Titaness who was the first great spouse of Zeus, indeed his equal (Hesiod, Theogony 896) and the mother of Athena. So, Athena was actually the daughter of wisdom. She was the goddess of wisdom and deep thought.
Zeus lay with Metis but immediately feared the consequences. It had been prophesied that Metis would bear a son more powerful than Zeus himself. In order to forestall these dire consequences, Zeus tricked her into turning herself into a fly and promptly swallowed her. He was too late: Metis had already conceived a child. In time she began making a helmet and robe for her fetal daughter. The hammering as she made the helmet caused Zeus great pain and Prometheus, Hephaestus, Hermes or Palamaon (depending on the sources examined) either cleaved Zeus's head with an axe or hit it with a hammer at the river Triton, giving rise to Athena's epithet Tritogeneia. Athena leaped from Zeus's head, fully grown, armed, and armored, and Zeus was none the worse for the experience.
Athena was the favorite child of Zeus and the patron deity of Athens after she gave them the gift of the olive tree.
Metis, a minor moon of the planet Jupiter, was named for her in 1979.
