Figure

Poseidon

Kings

In Greek narrative tradition Poseidon is a son of the Titans Cronus and Rhea, swallowed at birth and later freed alongside his siblings in the war against their father. When the three brothers divide the world by lot after the Titanomachy, Zeus receives the sky, Hades the underworld and Poseidon the sea, which he rules from an undersea palace and stirs with the trident that is his sign. Homer styles him the earth shaker for the earthquakes he sends, and his own myths run mostly to contests: for patronage of Athens against Athena, a contest he loses, and for control of the sea itself against rivals whose challenges he answers with storms.

Origins

Origin of the Namethe subject's own account

His name's etymology remains debated among philologists; one long-standing proposal reads it as husband of earth, connecting the second element to a root for earth or wife, though no reading commands full scholarly consensus. 2

History

Historical Notethe subject's own account

Poseidon competed with Athena for patronage of Athens and lost; the city's king, Cecrops, judged Athena's gift the olive tree superior to Poseidon's own gift. Poseidon kept a place on the Acropolis through his surrogate Erechtheus, and, by one account, sent a flood over the Attic plain to punish the Athenians for not choosing him. 2

Lord of the Sea and Shaker of the Earth

Poseidon was a son of Cronus and Rhea and, after the Olympians' victory over the Titans, received the sea as his share when he and his brothers Zeus and Hades divided the cosmos by lot, Zeus taking the sky and Hades the underworld while the earth and Olympus remained shared ground. Beyond the sea itself, Poseidon carried a cluster of related powers in Greek myth: he was called the Earth Shaker for his association with earthquakes, and he was credited with creating the first horse, which grounded his long standing patronage of horsemanship and chariot racing. His most famous local myth is his contest with Athena for patronage of Athens, in which he struck the Acropolis rock with his trident to produce a spring of seawater while Athena produced an olive tree, and the city's judges chose Athena's more useful gift, a decision Poseidon is said to have resented for a long time afterward. He fathered a large number of offspring across Greek myth, mortal and monstrous alike, including the Cyclops Polyphemus blinded by Odysseus in the Odyssey, whose suffering father then cursed Odysseus's own long journey home. Homer's Iliad also places Poseidon among the gods actively hostile to Troy, still resentful that the Trojan king Laomedon had once cheated him and Apollo of the payment he owed them for building the city's walls.

Isthmia and the God Sailors Actually Prayed To

Poseidon's worship reflected the two faces his myths already suggest, a god of the sea addressed by anyone whose livelihood or survival depended on it, and a god of earthquakes and horses addressed for entirely different, land bound reasons. Sailors and coastal communities across the Greek world kept shrines and made offerings to him before voyages and after safe returns, a practical devotional relationship distinct from the more literary myths of his rivalries, and cities well inland from any coast still maintained his cult for protection against earthquakes, a hazard the Greek world faced constantly. His major public sanctuary sat at Isthmia, near Corinth, where the Isthmian Games were held in his honor every two years, one of the four great Panhellenic athletic festivals alongside the Olympic, Pythian and Nemean Games, drawing competitors and spectators from across the Greek speaking world. Temples to Poseidon Hippios, protector of horses and horsemanship, were kept separately from his sea cult in several regions, particularly Thessaly and Arcadia, underscoring that ancient worshippers approached his different domains as distinct enough to warrant separate shrines and separate prayers rather than treating him as a single god invoked the same way for every need.
