2319: Poseidon and Amphitrite. Painting by Jan Gossaert, 1478-1532. Gemälde Galerie Kulturforum, Berlin.

Poseidon, the earth-shaker, was alotted the dominion of the sea (just as Zeus got the sky, and Hades the Underworld); and he received the trident from the CYCLOPES (just as Zeus got the thunderbolt, and Hades a helmet). Poseidon was the first to concern himself with seafaring, and the first to tame horses.

Birth and childhood

The Arcadians say that when Poseidon was born his mother declared to her husband Cronos, who used to swallow his offspring at birth, that she had given birth to a horse, and so she presented him a foal to swallow instead of the child, just as later she offered him a wrapped stone in place of Zeus. Rhea 1 committed the child Poseidon to Caphira (one of the OCEANIDS) and to the TELCHINES (see CORYBANTES), so that they would nurture him, much in the way as she later committed Zeus to the CURETES for his protection. But others say that Poseidon was swallowed by his father, as also were his siblings Hestia, Hera, Hades and Demeter; for they assert that only Zeus escaped that fate.

Lord of the sea

When Zeus had grown up, he asked Metis 1 to help him against his father Cronos, who was a stern tyrant; so she gave Cronos a drug, which forced him to disgorge first the stone with which Rhea 1 had deluded him, and then the children whom he had swallowed, among which Poseidon. And with the aid of his brothers and sisters Zeus waged war against Cronos and the TITANS, whom he defeated and cast into Tartarus, a place as far beneath the earth as heaven is above earth. Having won victory, they cast lots for the sovereignty, and to Zeus was allotted the dominion of the sky, to Poseidon the dominion of the sea, and to Hades the dominion of the Underworld. Then Poseidon constructed the brazen fence that runs round Tartarus and its gates of bronze, behind which the TITANS were confined (for Tartarus see also Underworld).

Plots against Zeus

Poseidon took once part in a minor conspiracy in heaven; for he, along with Hera and Athena, had agreed to put Zeus in bonds. However, he was saved by Briareus (one of the HECATONCHEIRES), whom Achilles' mother Thetis had called to Zeus' rescue; and by just squatting down close to him and through the mere display of his force, Briareus frightened Poseidon and the goddesses away.

Dispute with Helius

According to the Corinthians, this same Briareus acted as adjudicator arbitrating between Helius and Poseidon, who had a dispute concerning the lands about Corinth. He then assigned to Poseidon the Isthmus of Corinth including the adjacent lands, and gave to Helius the height above the city (Acrocorinthus).

Dispute with Hera

A similar dispute, though this time for the patronage of Argos, involved Poseidon and Hera. A tribunal of three RIVER GODS: Inachus, Cephisus, and Asterion 2, decided on this occasion that Argolis would belong to Hera and not to Poseidon. Disappointed with this judgement, the god made their waters disappear, and that is why they never provide any water except after rain, their streams being dry during the summer. But since little and much must compensate each other, Poseidon inundated many districts in Argolis because of the decisions of the RIVER GODS. Lerna is however, excepted; for it was here that Amymone 1 (one of the DANAIDS) yielded to Poseidon on condition that she might have water, and the god, being in love with her, revealed to her the springs at Lerna.

Dispute with Athena (I)

Yet another disagreement concerning the patronage of lands and cities arised between Poseidon and Athena in relation to Troezen. But Zeus commanded them to hold this city in common, and so they did. This dispute took place during the reign of King Althepus, himself son of Poseidon and Leis, the daughter of Orus 1, predecessor of Althepus.

Dispute with Athena (II)

Poseidon, they say, was the first who came to Attica; and with a blow of his trident on the Acropolis, he produced a sea or, as some say, just a well of sea-water that could be seen in the Erechtheum on the Acropolis not far from the outline of the trident on the rock. These were the evidences in support of Poseidon's claim to the land. But Athena, coming after him, planted an olive tree and claimed the land; and since they fought for the possession of the country, Zeus parted them and appointed the OLYMPIANS as arbiters, who adjudged the city to Athena, because King Cecrops 1 witnessed that she had been the first to plant the olive tree. Athena called the city Athens after herself, but Poseidon, angry at the verdict flooded Attica. However, some say that it was Zeus who ajudged Athens to Athena, and that Poseidon never flooded the country because Hermes forbade him to do so. In any case, in the shrine of Erechtheus there remained preserved a long time an olive tree and a pool of salt water which had been set there by Athena and Poseidon as tokens when they contended for the city.


Zeus and Poseidon were once rivals for the hand of Thetis, but when Themis, or the MOERAE, or Proteus 2 prophesied that the son born of Thetis would be mightier than his father, they withdrew. Zeus then, bade his grandson Peleus to marry her, and from their union Achilles was born, who was mightier than his father.


It is said that when Poseidon decided to marry the Oceanid Amphitrite, she, wishing to remain a virgin, escaped and fled to Atlas. Poseidon then send many to look for her, and among them a certain Delphin, who after long wanderings, found her and persuaded her to marry Poseidon, organizing himself the whole wedding. For this reason, they say, Poseidon put the dolphin among the CONSTELLATIONS.

The walls of Troy

When Laomedon 1 was king of Troy, Apollo and Poseidon decided to put him to the test, and assuming the likeness of mortal men, fortified the city for wages. But when the work was done, King Laomedon 1 would not pay their wages; so Apollo sent a pestilence, and Poseidon sent a sea-monster that snatched away the people of the plain. Since oracles foretold deliverance from these calamities if Laomedon 1 would expose Hesione 2 to be devoured by the sea-monster, he exposed her by fastening her to the rocks near the sea, but Heracles 1 delivered her.

More monsters

On another occasion, Poseidon sent another sea-monster against the Teucrians because Hierax 2, otherwise a righteous man, was devoted to Demeter, and would not honour him. Poseidon also shared the wrath of the NEREIDS, when Queen Cassiopea 2 boasted of being better than them; and he sent a flood and yet another sea-monster to invade the land. The seer Ammon 3 predicted deliverance from the calamity if the queen's daughter Andromeda were exposed as a prey to the monster. So her father King Cepheus 1 was then compelled by the Ethiopians to do it, and he bound Andromeda to a rock. But the girl was rescued by Perseus 1, who slaughtered the beast. Poseidon heard his son Theseus when he, believing Phaedra's charges against Hippolytus 4, prayed to the god that Hippolytus 4 might perish. And when this young man was riding in his chariot and driving beside the sea, Poseidon sent up a bull from the waves, and the horses were frightened, the chariot dashed to pieces, and Hippolytus 4, entangled in the reins, was dragged to death.


In the legend of Atlantis, which is not connected to other myths except for the names of Atlas and Poseidon, the first ten kings of Atlantis (five pairs of twins) were all sons of Poseidon and Cleito 2. The first born was Atlas, who was appointed to be king over the rest, and the island was called after him.
