The Greek god of the sea, commonly identified with the trident, is Poseidon. He is one of the major Olympian gods, associated not only with the sea, but also with earthquakes and horses. Poseidon's character embodies the unpredictable nature of the ocean, reflecting both its vastness and its potential for destruction. Worship of Poseidon highlighted the importance of maritime journeys in ancient Greek culture and the need for divine favor in navigating the seas.
