Poseidon
Poseidon, marble statue from Melos, 2nd century bce; in the National Archaeological Museum, Athens.
In Greek mythology, Poseidon became ruler of the sea after the overthrow of his father, Cronus. Along with his brothers Zeus and Hades, Poseidon was swallowed by Cronus but later liberated. After deposing Cronus, the three brothers divided the realms by lot: Zeus received the sky, Poseidon the sea, and Hades the underworld. Poseidon is one of the 12 Olympians, second in power only to Zeus. His primary symbols are the trident and horses, and he is also associated with earthquakes.12
