Poseidon was the Lord of the sea. He was a moody and violent god. He was also called the Earth shaker for when he hit the earth with his trident, the earth trembled and shook. Surprisingly, though, when he was in his good mood he would raise new islands and still the sea. Poseidon was rarely home for he loved the sea and for days he would race the waves. Poseidon had many wives but his true wife, Amphitrite, was never jealous. Poseidon had only one child and his name was Triton. Poseidon was mean but he could be nice if he wanted.
