'''Poseidon''' is one of the Twelve Olympians and the Olympian god of the sea, earthquakes, floods, drought and horses. He was depicted as a mature man with a sturdy build and dark beard holding a trident (a three-pronged fisherman's spear).

In ancient Greek religion and mythology, presiding over the sea, storms, earthquakes and horses. He was the protector of seafarers and the guardian of many Hellenic cities and colonies. In pre-Olympian Bronze Age Greece, Poseidon was venerated as a chief deity at Pylos and Thebes, with the cult title "earth shaker"; in the myths of isolated Arcadia, he is related to Demeter and Persephone and was venerated as a horse, and as a god of the waters. Poseidon maintained both associations among most Greeks: he was regarded as the tamer or father of horses, who, with a strike of his trident, created springs (the terms for horses and springs are related in the Greek language). His Roman equivalent is Neptune.

In the standard version, Poseidon was born to the Titans Cronus and Rhea, the fifth child out of six, born after Hestia, Demeter, Hera and Hades in that order. Because Poseidon's father was afraid that one of his children would overthrow him like he had done to his own father, Cronus devoured each infant as soon as they were born. Poseidon was the last one to suffer this fate before Rhea decided to deceive Cronus and whisk the sixth child, Zeus, away to safety, after offering Cronus a rock wrapped in a blanket to eat. Once Zeus was grown, he gave his father a powerful emetic that made him gorge up the children he had eaten. The five children emerged from their father's belly in reverse order, making Poseidon both the second youngest child and the second oldest at the same time. Armed with a trident forged for him by the Cyclopes, Poseidon with his siblings and other divine allies defeated the Titans and became rulers in their place.

Homer and Hesiod suggest that Poseidon became lord of the sea when, following the overthrow of his father Cronus, the world was divided by lot among Cronus' three sons; Zeus was given the sky, Hades the underworld, and Poseidon the sea, with the Earth and Mount Olympus belonging to all three. In Homer's Iliad, Poseidon supports the Greeks against the Trojans during the Trojan War; in the Odyssey, during the sea-voyage from Troy back home to Ithaca, the Greek hero Odysseus provokes Poseidon's fury by blinding his son, the Cyclops Polyphemus, resulting in Poseidon punishing him with storms, causing the complete loss of his ship and companions, and delaying his return by ten years. Poseidon is also the subject of a Homeric hymn. In Plato's Timaeus and Critias, the legendary island of Atlantis was Poseidon's domain.

As the god of earthquakes, Poseidon was also connected to dry land, and many of his oldest places of worship in Greece were inland, though these were sometimes centered on pools and streams or otherwise associated with water. In this aspect, he was known as enosichthon and ennosigaios (“earth-shaker”) and was worshipped as asphalios (“stabilizer”). As the god of horses, Poseidon is thought likely to have been introduced to Greece by the earliest Hellenes, who also introduced the first horses to the country about the 2nd century bce. Poseidon himself fathered many horses, best known of which was the winged horse Pegasus by the Gorgon Medusa.

Poseidon’s offspring were myriad. He was the father of Pelias and Neleus by Tyro, the daughter of Salmoneus, and thus became the divine ancestor of the royal families of Thessaly and Messenia. Many of his sons became rulers in other parts of the ancient Greek world. Otherwise he had many monstrous offspring, including giants and savage creatures, such as Orion, Antaeus, and Polyphemus. Progenitor of many, with several consorts, Poseidon also was married to the Oceanid Amphitrite, with whom he also had multiple offspring, including the sea creature Triton.

The chief festival in Poseidon’s honour was the Isthmia, the scene of famous athletic contests (including horse races), celebrated in alternate years near the Isthmus of Corinth. His character as a sea god eventually became his most prominent in art, and he was represented with the attributes of the trident, the dolphin, and the tuna.

Poseidon is famous for his contests with other deities for winning the patronage of the city. According to legend, Athena became the patron goddess of the city of Athens after a competition with Poseidon, though he remained on the Acropolis in the form of his surrogate, Erechtheus. After the fight, Poseidon sent a monstrous flood to the Attic plain to punish the Athenians for not choosing him. In similar competitions with other deities in different cities, he causes devastating floods when he loses. Poseidon is a horrifying and avenging god and must be honored even when he is not the patron deity of the city.

Some scholars suggested that Poseidon was probably a Pelasgian god or a god of the Minyans. However it is possible that Poseidon, like Zeus, was a common god of all Greeks from the beginning.
