Who is Poseidon?
In Greek mythology, Poseidon — along with Demeter, Hades, Hera, Hestia, and Zeus — is one of the children of the Titans Cronus and Rhea. He is considered patron of the waters, earthquakes, horses, and navigation, and his counterpart in Roman mythology is Neptune, from whose name we get the name of the eighth planet. He is associated with the trident which he carried.
