What is the term for mock combat performed by gladiators?

The term for mock combat performed by gladiators is known as "prolusio." This term refers to preliminary events or demonstrations that took place to showcase the skills and readiness of gladiators before the actual combat began. During a prolusio, participants would engage in simulated fighting to entertain the audience and build excitement for the upcoming matches.

In contrast, the other terms have different meanings in the context of gladiatorial games. "Pollice verso" refers to the gesture used by the crowd to signal the fate of a defeated gladiator, while "nos morituri te salutamus" translates to "we who are about to die salute you," a phrase reportedly spoken by gladiators before they entered battle. "Murmillo" is a specific type of gladiator, typically characterized by their use of a large rectangular shield and a sword. Understanding these distinctions helps clarify why "prolusio" is the correct answer in this context.
