The Greek god of the sea, known for wielding a trident, is Poseidon. As one of the twelve Olympian deities, Poseidon governs oceans, storms, and earthquakes, symbolizing the mighty forces of nature. He is often depicted alongside marine creatures and is associated with both destruction and fertility of the seas. Poseidon’s character illustrates the duality of water as both a life-giving force and a perilous element. His importance in Greek mythology underscores the deep connection ancient Greeks had with the sea, affecting trade, culture, and religion.
