Answer:
Poseidon, in ancient Greek religion, god of the sea (and of water generally), earthquakes, and horses. He is distinguished from Pontus, the personification of the sea and the oldest Greek divinity of the waters. The name Poseidon means either “husband of the earth” or “lord of the earth.” Poseidon is best known for holding his trident (a large three-pronged spear), and as well as being the god of the sea, he's also known as the god of earthquakes, storms and horses too. It's even believed that Poseidon himself invented horses when Demeter asked him to create the world's most beautiful animal. Poseidon was one of the most powerful gods in ancient Greek mythology, and he controlled more than just the sea. In ancient Greek culture, Poseidon was held responsible for earthquakes, rivers, floods, droughts, and anything involving water in general. Some myths also claim he gave humans the first horse.
