If you were doing a project to make a Roman helmet, why would you choose a to make the helmet?

Ever heard of the gladiators, they originated in Rome.

Rome was a place full of fighting, they would battle all day, and I don't just mean their enemies, they would fight each other too.

Helmets were a main piece of equipment during their battles, because not only did it protect them, during war with outsiders, the helmets were used as ways to identify positions. Such as Centurion from soldier.
