Triton, a sea god, (son of Neptune and of Salacia, a marine nymph), whom the poets feigned to be the trumpeter (tubicen) of Neptune, (Vaillant, Col.). The effigy of a Triton, a human form above, a fish below the waist, frequently appears on ancient coins, both Roman and Greek, where it serves occasionally as a symbol of the sea. He is seen under a quadriga drawn by Jupiter, on a coin of the Cornelia family. The same figure on one side of Venus, whilst Cupid stands on the other, occurs on a brass medallion of Faustina jun. A Triton, with a Nereid, is drawing the car of Venus, on a colonial medal of Corinth. On a medal of Maximinus and Maximus, two Tritons support a plateau on which Neptune sits.
