Poseidon

Poseidon, one of the twelve Olympians, was also the god of storms and horses and the protector of seafarers. When the world was divided by lot among the sons of Cronus, Zeus received the sky, Hades the underworld and Poseidon the sea.

In Bronze Age Pylos and Thebes he was a chief deity, called Earth Shaker. He lost Athens to Athena, and in the Odyssey his anger over the blinding of his son Polyphemus kept Odysseus at sea for ten years.
