"The
Hoplomachus (Greek "armed fighter") wore quilted, trouser-like leg wrappings, loincloth, a belt, a pair of long shin-guards or greaves, an arm guard (manica) on the sword-arm, and a brimmed helmet that could be adorned with a plume of feathers on top and a single feather on each side. He was equipped with a gladius and a very small, round shield. He also carried a spear, which the gladiator would have to cast before closing for hand-to-hand combat. The hoplomachi were paired against the Myrmillones or Thraeces. They may have developed out of the earlier '"Samnite" type after it became impolitic to use the names of now-allied peoples"
"The
murmillo (plural
murmillones) or
myrmillo wore a helmet with a stylised fish on the crest (the
mormylos or sea fish), as well as an arm guard (
manica), a loincloth and belt, a gaiter on his right leg, thick wrappings covering the tops of his feet, and a very short greave with an indentation for the padding at the top of the feet. They are heavily armoured gladiators: the
murmillo carried a
gladius (64–81 cm long) and a tall, oblong shield in the legionary style.
Murmillones were typically paired with
Thracian, but occasionally with the similar
hoplomachus.

"The
retiarius ("net fighter") developed in the early
Augustan period. He carried a
trident, a dagger, and a net. The
retiarius wore a loincloth held in place by a wide belt and a larger arm guard (
manica) extending to the shoulder and left side of the chest. He fought without the protection of a helmet. Occasionally a metal shoulder shield (
galerus) was added to protect the neck and lower face. A tombstone found in Romania shows a
retiarius holding a dagger with four spikes (each at the corner of a square
guard) instead of the usual bladed dagger. This was previously thought to be an artistic invention or perhaps a ceremonial weapon, but a recent discovery of a gladiator graveyard found that several of the remains had four odd-looking marks that form the outline of a square on their bones which is consistent with the use of such a weapon. A variation to the normal combat was a
retiarius facing two
secutores at the same time. The
retiarus stood on a bridge or raised platform with stairs and had a pile of fist-sized stones to throw at his adversaries. While the
retarius tried to keep them at bay, the
secutores tried to scale the structure to attack him. The platform, called a
pons (bridge), may have been constructed over water.
[22] Retiarii usually fought
Secutores but sometimes fought
Myrmillones.
[23] There was an
effeminate class of gladiator who fought as a
retiarius tunicatus. They wore tunics to distinguish them from the usual
retiarius, and were looked on as a social class even lower than
infamia.
