Poseidon

Poseidon was the god of the seas, the rivers, the drinking water and all aquatic features, the earthquakes, floods and drought. Like Zeus and Hera, Poseidon was also son of titans Cronus and Rhea and he was considered to be the protector of sailors and fishermen. His weapon and symbol was his trident and he would strike the ground with it to produce an earthquake. This earned him the nickname “Earth-shaker.” Other symbols of his were the dolphin and the horse.
