This marble statue is likely a Roman copy of a Hellenistic original done in bronze. The original probably dates from around 225 BCE, commissioned by King Attalus of Pergamon (in present-day Turkey) to commemorate his victory over an army of Gauls. The Gaul, dying of his wounds, is wearing a torque around his neck, a distinctive type of jewelry worn by the Gauls. It’s now in the Capitoline Museum in Rome.
