Poseidon

Poseidon, in Greek mythology, god of the sea, the son of the Titans Cronus and Rhea, and the brother of Zeus and Hades. Poseidon was the husband of Amphitrite, one of the Nereids, by whom he had a son, Triton. Poseidon had numerous other love affairs, however, especially with nymphs of springs and fountains, and was the father of several children famed for their wildness and cruelty, among them the giant Orion and the Cyclops Polyphemus. Poseidon and the Gorgon Medusa were the parents of Pegasus, the famous winged horse.

Poseidon plays a prominent part in numerous ancient myths and legends. He contended unsuccessfully with Athena, goddess of wisdom, for the control of Athens. When he and Apollo, god of the sun, were cheated of their promised wages after having helped Laomedon, king of Troy, build the walls of that city, Poseidon's revenge against Troy knew no bounds. He sent a terrible sea monster to ravage the land, and during the Trojan War he helped the Greeks.

In art, Poseidon is represented as a bearded and majestic figure, holding a trident and often accompanied by a dolphin. Every two years the Isthmian Games, featuring horse and chariot racers, were held in his honor at Corinth. The Romans identified Poseidon with their god of the sea, Neptune.
