Zeus and Athena
How Athena Was Born
Zeus is the ruler of all gods (being a god himself) and is the father of Athena. Athena is the god of crafts and domestic crafts. Athena also aided the heroes Perseus, Jason, Cadmus, Odysseus, and Heracles in their quests. Metis was the daughter of the Ocean who was known for her wisdom.
Zeus was once married to Metis, a daughter of Ocean who was known for her wisdom. When Metis became pregnant, Zeus was warned by Earth that a son born to Metis would overthrow him, just like how he took his own father's throne.
So Zeus swallowed Metis. In time he got an enormous headache and summoned help from the craftsman god Hephaestus. Hephaestus split open Zeus's forehead with an ax, and Athena came out fully armed.
