Poseidon was the son of Cronus and Rhea, the king and queen of the Titans.

 After being born, Poseidon was swallowed by his father Cronus because of a prophesy that said Cronus' children would someday overthrow him.

Poseidon was eventually saved by his younger brother Zeus.

Poseidon had complete power and control over the ocean. He could create storms to sink ships or clear weather to help them along.

He also could cause earthquakes on land which earned him the title "earth-shaker."

Poseidon is pictured with a three pronged spear called a trident.

He usually has curly hair and a beard. Sometimes he is shown riding his chariot which is pulled by hippocampuses (horses that have fish tails).

One of Poseidon's most famous deeds is the creation of the horse. There are two stories that tell how he did this. The first says that he fell in love with the goddess Demeter. In order to impress her he decided to create the world's most beautiful animal.
