Poseidon, one of the central figures in ancient Greek mythology, is primarily known as the god of the sea, but his influence extends to earthquakes and horses as well. Known for his fierce temper and unpredictable nature, Poseidon was a powerful Olympian deity, second only to Zeus in prestige. He is often depicted as a robust man with blue or green hair and a beard, holding a trident, which symbolizes his authority over the oceans and his ability to stir up storms and cause tidal waves.

Born to Cronus and Rhea, Poseidon was swallowed at birth by his father but later rescued by his siblings, including Zeus and Hades. After the defeat of the Titans, the three brothers divided the cosmos: Zeus took the sky, Hades ruled the underworld, and Poseidon claimed the sea. This division reflects the ancient Greeks’ understanding of the world, with Poseidon embodying the mysteries and dangers of the oceans.

Poseidon’s mythology includes many famous stories, such as his rivalry with Athena for the patronage of Athens, which he lost when she offered the olive tree as a gift to the city. He is also associated with numerous sea creatures and often accompanied by nymphs and other aquatic beings. Worshipped across the Greek world, Poseidon had numerous temples, and festivals, and was invoked by sailors seeking safe passage.

In sum, Poseidon represents the dual nature of the sea—capable of providing sustenance and transport, yet also capable of unleashing chaos and destruction. His legacy continues to influence art, literature, and popular culture, where he is often portrayed in various adaptations of ancient myths.
