The Greek god of the sea known for his tempestuous nature is Poseidon. He wields a trident and governs not only the oceans but also earthquakes and horses. Poseidon’s unpredictable temperament reflects the ocean's chaos and power, often leading to fear and respect among mortals. His myths frequently explore themes of dominion over nature, the consequences of human hubris, and the need for appeasement through sacrifices. Blessed with both creative and destructive powers, Poseidon plays a crucial role in Greek mythology.
