Neptune

Neptune (Nep´tune), god of the sea, was a son of Saturn and Cybele, and brother to Jupiter and Pluto. He quarreled with Jupiter because he did not consider that the dominion of the sea was equal to Jupiter’s empire of heaven and earth; and he was banished from the celestial regions, after having conspired with Pluto to dethrone Jupiter. Neptune was married to Amphitrite, daughter of Oceanus and Tethys, by whom he had a son named Triton. He was also father of Polyphemus (one of the Cyclopes), Phoreus, and Proteus. Neptune is represented as being seated in a shell chariot, drawn by dolphins or sea-horses, and surrounded by Tritons and sea-nymphs. He holds in his hand a trident, with which he rules the waves. Though a marine deity, he was reputed to have presided over horse-training and horse-races; but he is principally known as the god of the ocean; and the two functions of the god are portrayed in the sea horses with which his chariot is drawn, the fore-half of the animal being a horse, and the hind-half a dolphin. Ships were also under his protection, and whenever he appeared on the ocean there was a dead calm.
