Poseidon was one of the six children of Cronus and Rhea and brother of Zeus. He was allotted the kingdom of the sea but he was also considered the god of horses and earthquakes. This is why he was called "the earth-shaker". He rarely lived on Olympus, preferring the depths of the ocean. He was sitting on a famous chariot drawn by immortal horses and holding in his hand the famous trident, forged by the Cyclops. When Poseidon was angry, he plunged the trident into the sea and shook it whole from end to end. The sailors prayed to Poseidon so that he spares them from his wrath.
