In Greek mythology, Poseidon (Greek: Ποσειδῶν) is one of the main Olympian gods, the supreme god of water (lakes, rivers, springs) and by extension the sea (hence the name Pelagaios). The main symbol – emblem of Poseidon is the trident (= with three points), or trident spear or simply the trident, which was both a scepter of recognition and a means or weapon of enforcing his will. With it, depending on the sea or rocks, it caused natural disasters, storms, earthquakes, sinkings, volcanic eruptions, etc. but also vice versa peace, calm, solidity until the emergence of land, or the gushing of water, hence the derivative verb τριαινόω (= dissolve, move, stir, excavate, overturn, knock down, etc. always using a trident).
