Meaning and background

The story behind Poseidon

Poseidon belongs to ancient Greek mythology, where he rules the sea and is associated with earthquakes and horses. He is often identified by a three-pronged trident, a more specific image than simply calling him a ‘water god’. The name has a long documented religious history, but the deeper linguistic derivation of Poseidon itself remains debated. Its three emphatic syllables make it a dramatic pet name without implying the animal has any mythical powers.

Meaning
Name of the Greek god of the sea, earthquakes and horses. Source
