What is the name of the gladiator armed with a lasso?

The name of the gladiator armed with a lasso is indeed Laqueator. This type of gladiator was unique in that he used a lasso as his primary weapon, allowing him to ensnare opponents from a distance. The Laqueator's fighting style relied on agility and skill in throwing the lasso to immobilize or catch opponents before closing in for a more traditional combat.

In contrast, the Hoplomachus was characterized by his heavily armored combat style and typically fought with a spear and a dagger. The Thracian, known for his curved sword (sica) and small shield, engaged in fast-paced melee combat. The Murmillo, another well-known type of gladiator, was recognized for his fish-shaped helmet and armament that usually included a gladius and a large rectangular shield. Each of these gladiatorial types had their own distinct weapons and fighting styles, making them unique in the arena, but none employed a lasso as part of their arsenal like the Laqueator.
