In ancient Greek mythology, Poseidon was worshipped as the God of the Sea.
Historically, Poseidon was always portrayed as a mature man with a fully-grown beard, and equipped with his best known weapon, the trident, which he used to shake the earth, shatter rocks and create storms, causing devastating earthquakes and tsunamis. His other symbols include a bull, dolphins, horse and fish.
Poseidon was one of six children and the second of three brothers, Zeus, Poseidon and Hades, born to Rhea and Cronus, the ruler of the Titans. Having overthrown their father, the three brothers divided the universe between them. Zeus took control of the heavens, Poseidon the sea, and Hades the underworld.
