Who is the Greek god of the sea?

The story behind the answer

Poseidon is the Greek god of the sea, sailors, and storms, often depicted with a trident that could calm or shatter waves. He also bore the title “Earth-Shaker” for causing earthquakes. By contrast, Zeus rules the sky and thunder, Hades governs the underworld, and Aeolus is keeper of the winds—not the sea itself.

In myth, Poseidon appears in tales like the Odyssey, where his wrath prolongs Odysseus’s voyage, and in his rivalry with Athena for Athens. He’s also associated with horses, said to have created them with a strike of his trident. Memory tip: P is for Poseidon, Pools, and Ports—think “P” for the waters where ships depart and return.
