Triton of the Fontana del Moro

Originally, Triton is a mythological Greek god, messenger of the sea, son of Poseidon and Amphridite, both gods of the sea. Triton's lower half is that of a fish, while the top half is presented in a human figure. However, the term Triton came to designate a class of mermaid-like creatures, which could be male or female, and usually formed the escort of marine divinities. They are a race of sea gods and goddesses born from Triton.  This statue may be found in the Fontana del Moro in Rome, on the Piazza Navona.
