The gladiator "Secutor" (chaser in English), got his name from his fighting technique. Infact he used to chase his opponent around the Arena... He wore a round helmet with crest and two small round eye holes.
His principal opponent was the Retiarius...
so the rounded shape of the Secutor's Helmet was less likely to become entagled in the net of the Retiarius.
His right arm was protected with a leather or metal armor, and he carried a short sword called Spatha.
Also he had a large shield and his left leg was covered with a metal leg guard called Ocrea.
