Roman gladiators were separed into distinct types according to their equipment. The fisherman-themed retiarius or 'net-man' is perhaps the most recognizable today. Associated with the Roman God Neptune, retiarii wielded a trident as their main weapon, a net for ensnaring foes, and a dagger as a last resort. The only armor they wore covered their left arm and shoulder, making them the least protected of all gladiators. The usual opponent of the retiarius was the secutor or 'pursuer' whose fin-crested helmet resembled the head of a fish. As such, their combat was a stylized version of the struggle between a fisherman and his catch.
