Greek god Poseidon (god Neptune, in Roman mythology) is best known as the God of Sea, but he was also the god of earthquakes and horses. He was the son of Cronus and Rhea. Just like his brothers and sisters (Hades, Hestia, Demeter and Hera), he was swallowed by his father right after he was born, but later he was brought up again (there is also another version, according to which Rhea told Cronus she had given birth to a horse and presented him a foal to swallow. God Poseidon grew up in a flock of lambs). Together with his brothers, he took part in the Titanomachy.
