Athena is the goddess of Wisdom and Intelligence from Greek Mythology. She is the favorite child of the King of Gods, Zeus. She was a goddess who only partook in wars that defended the country or state that was being attacked.
The story of Athena's birth started when Zeus began to pursue Athena's mother, Metis, the goddess of wisdom, prudence and deep thought.
Metis was the daughter of Oceanus and Tethys, both of which were Titans. The two ruled over all bodies of water and their children were lesser gods of rivers and goddesses of water, who were called Oceanids. The two Titans did not participate in the attack of Zeus by the rest of the Titans, and therefore were allowed to continue ruling over their watery kingdom.
When Zeus started to chase after Metis, Metis ran away from him, changing into many forms to escape him. While Zeus was after Metis, he was warned that the first child of Metis would be a girl and the second would be a boy with the power to overthrow Zeus. So when Metis let her guard down, Zeus swallowed her and her unborn child.
After some time went by, Zeus began to have massive headaches that made him scream so loud that his screams were heard on earth. Hermes, taking control of the situation, asked Hephaestus to split Zeus's head open. When Hephaestus used a wedge to split Zeus's skull, out sprang Athena, fully clothed (as her mother made her clothes and armor while inside) and fully grown (do to the amount of time she spent inside of her father's head). She then became the goddess of Intelligence and wisdom.
Some symbols of Athena are owls, doves, olive trees, onyx, and so on. In myths, she often helped hero's such as Jason, Perseus, and Hercules (who was her half-brother).
