Poseidon was a son of Cronus and Rhea. In most accounts he is swallowed by Cronus at birth but later saved, with his other brothers and sisters, by Zeus. However in some versions of the story, he, like his brother Zeus, did not share the fate of his other brother and sisters who were eaten by Cronus. He was saved by his mother Rhea, who concealed him among a flock of lambs and pretended to have given birth to a colt, which she gave to Cronus to devour.According to John Tzetze the kourothrophos, or nurse of Poseidon was Arne, who denied knowing where he was, when Cronus came searching; according to Diodorus Siculus Poseidon was raised by the Telchines on Rhodes, just as Zeus was raised by the Korybantes on Crete.
According to a single reference in the Iliad, when the world was divided by lot in three, the three godley brothers divided there domanin. Zeus received the Sky, Hades the Underworld and Poseidon the Seas.
Being already the god of the Seas he lived in an underwater palace under the Aegean sea with his queen Amphitrite.
