The Meaning of Trident of Poseidon

The Trident was the signature weapon and symbol of Poseidon, god of the sea, earthquakes, and horses.‌​‌​‍​‌​‌​‍​‌​‌​‍​‍​‍​‌​‍​‌​‍​‌​‍​‌​‌​‍​‌​‍​‍​‌​‌​‌​‍​‌​‍​‌​‍​‌ It was forged by the CyclopesBrontes, Steropes, and Arges — during the Titanomachy, the war between the Olympian gods and the Titans. In gratitude for their release from Tartarus, the Cyclopes crafted supreme weapons for each of the three brothers: the thunderbolt for Zeus, the helm of invisibility for Hades, and the trident for Poseidon. With the trident, Poseidon could command the oceans, raising and calming storms at will. He could strike the earth to cause earthquakes — earning him the epithet Ennosigaios, "Earth-Shaker." When he struck a rock with the trident, salt water gushed forth, as in his famous contest with Athena for patronage of Athens. The trident also served to split coastlines, create islands, and calm the seas for favoured sailors. In art, Poseidon is almost never depicted without it, and the weapon became so closely identified with maritime power that Roman mosaics placed it in the hands of Neptune for centuries afterward.
