In Greek mythology, Poseidon carried a three-pronged weapon called the trident.
Poseidon was the Olympian god of the sea, earthquakes, and horses. He was one of the three sons of Cronus and Rhea who divided the cosmos after the defeat of the Titans. Zeus received the sky, Poseidon received the sea, and Hades received the underworld.
The trident became Poseidon’s most recognizable attribute. Myths describe it as a powerful weapon capable of stirring the sea, causing earthquakes, and splitting rocks. His connection with horses also appears in several traditions, including stories that credit him with creating or fathering a divine horse.
Poseidon’s Roman equivalent was Neptune. He was worshipped widely by seafaring communities, especially in coastal regions of the Greek world. Although he lived among the Olympians, his authority extended over a realm separate from Mount Olympus.
