The Story of Poseidon
Poseidon is one of the most ancient Greek divine names, with roots stretching back to Proto-Indo-European. The name is commonly broken down as posis (husband, lord) and da (earth), making it lord of the earth or husband of the earth — a title that reflected his dominion over the seas, earthquakes, and horses. He was one of the three brother-gods who divided the world: Zeus ruled the sky, Hades the underworld, and Poseidon the seas.
Poseidon as a given name has gained popularity alongside the broader trend of mythological names and was further boosted by Rick Riordan's Percy Jackson series, where Poseidon is Percy's divine father. The fantasy series introduced Poseidon to millions of young readers as a powerful, complex character rather than merely an abstract deity.
In ancient Greece, Poseidon was among the most powerful and feared of the Olympians. Sailors prayed to him before voyages, and earthquakes were attributed to him striking the earth with his trident. The city of Athens was named after Athena rather than Poseidon after he and Athena competed for patronage — their contest is depicted on the Parthenon.
