Poseidon was one of the 12 Olympians in ancient Greek religion and myth. He was god of the Sea and other waters, of earthquakes, and of horses. He was protector of seafarers, and of many Hellenic cities and colonies. In Homer's Iliad, Poseidon supported the Greeks against the Trojans during the Trojan War. In the Odyssey, during the sea-voyage back from Troy to Ithaca, the Greek hero Odysseus provokes Poseidon's fury by blinding his son the Cyclops Polyphemus, resulting in Poseidon punishing him with storms, the complete loss of his ship and companions, and a ten-year delay.His consort was the goddess Amphitrite. In the roman religion, she became the goddess of salt waters specifically.
