Who is Poseidon in Greek mythology?
In Greek mythology, Poseidon is the god of the sea, earthquakes, and horses. He is one of the twelve Olympians, second in power only to his brother Zeus, the god of the sky and chief deity in Greek religion. Poseidon, Zeus, and Hades overthrew their father, Cronus, establishing a new divine order. Poseidon's domain was the sea, and he lived beneath it, unlike most other gods who resided on Mount Olympus. His primary symbol and weapon was the trident. Poseidon is known for his contest with Athena for control of Athens and his role in persecuting Odysseus. The Romans identified him with Neptune as the god of the sea.
