Greek Mythology is a huge aspect that includes myths about Greek gods and goddesses and the Greek teaching.
This is Zeus.He overthrew his father, Cronus, and then drew lots with his brothers Poseidon and Hades, in order to decide who would succeed their father on the throne. Zeus won the draw and became the supreme ruler of the gods, as well as lord of the sky and rain. His weapon was a thunderbolt
Each storyteller told the stories in their own way, but whatever power and personality a god had was consistent from story to story. For example, Zeus was the king of all the gods, and only Zeus could throw lightning bolts or the "Medusa" a monster that if you look at her would turn you in a stone.
