A fighter who wore no armor, but who carried a net and a trident (a three-pronged spear).

Developed in the early Augustan era, the retiarius (net-fighter) carried a trident, a dagger, a net, and no helmet. Except for a loincloth, a manica on his left arm, and a metal shoulder-guard (galerus) above the manica, the retiarius fought naked and was always paired with a secutor.
