Statue of Neptune (Latin: Neptūnus [nɛpˈtuːnʊs]) is the Roman god of freshwater and the sea in Roman religion. He is the counterpart of the Greek god Poseidon.[3] In the Greek-inspired tradition, he is a brother of Jupiter and Pluto; the brothers preside over the realms of heaven, the earthly world (including the underworld), and the seas. Salacia is his wife.

Depictions of Neptune in Roman mosaics, especially those in North Africa, were influenced by Hellenistic conventions.He was likely associated with freshwater springs before the sea.Like Poseidon, he was also worshipped by the Romans as a god of horses, as Neptunus equestris (a patron of horse-racing)
