when was poseidon born
Poseidon (born Eugene Poseidon Theodore Fiskmore III, October 8, 843 B.C. in the Marianas Trench) is the god of the sea, as well as horses, earthquakes, sporks, bubbles, and he is also King of Atlantis.
Pausanias, for example, mentions in his Description of Greece that Poseidon was born and concealed near the city of Mantinea in Arcadia. The god was hidden from Cronus there in a flock of sheep. An interesting detail: there was a well there in the time of Pausanias that was still called 'Lamb'.
