You smile at the oddly shaped helmet of the Secutor ("pursuer"), who usually confronts the Retiarius in the arena. You realize the utility of this egg-shaped helmet that is smooth all over, with no feathers or visor that can easily catch in the net of the Retiarius, but you cannot help thinking it makes him look like some deep-sea creature, and you imagine how those two eye-holes must limit his range of vision.
