Poseidon's trident
A trident /ˈtraɪdənt/ is a three-pronged spear. It is used for spearfishing. Historically it was used as a polearm. Gladiators used them in Ancient Rome after they cast a net to trap their opponent. The trident is the weapon of Poseidon, or Neptune, the god of the sea in classical mythology. In Hindu mythology it is the weapon of Shiva and goddess Durga, known as trishula (Sanskrit for "triple-spear"). The word "trident" comes from the French word trident, which in turn comes from the Latin word tridens.
