We know the next two coins will depict the Thraex and the Essedarius but there are many other types of gladiators that fought in the various arenas of the Roman Empire. Here are some quick descriptions of the more important ones, although not necessarily the last four coins.
THRAEX: Thracian in origin, they wer similar to Hoplomachi whom they were often paired to fight, the main difference was the stylised griffin on the helmet crest and the use of a 34 cm long Thracian curved sword in place of the Roman gladius. Their shields were small and square-shaped shield called parmula. They are thought to have replaced Gauls in the arena after that country made peace with Rome.
ESSEDARIUS: No doubt an imposing site in the arena, the Essedarius fought from a chariot. It isn’t known if they were in the chariot alone or had a driver. They normally fought with a spear and a sword as a side-arm but sometimes also had a small shield for defence. They charged their opponent with their chariot until the opposing gladiator was either impaled by the spear, trampled by the horses, or run over by the wheels of the chariot. They were relatively hard to defeat due to the speed of the chariot, but once the wheels were taken out they were easy to kill, if they didn’t know how to ride a horse. It was a common tactic that if their chariot was broken they used one of the horses from the chariot as a mount.
PROVOCATORES: Meaning challenger, the provocator fought with weapons similar to legionary armature in the late Republican and early Imperial era. In the late Imperial era armament followed changes in arena fashion only. Provocatores have been shown wearing a loincloth, a belt, a long greave on the left leg, a manica on the lower right arm, and a visored helmet without brim or crest, but with a feather on each side. They were the only gladiators protected by a breastplate (cardiophylax) which is usually rectangular, later often crescent-shaped. They fought with a tall, rectangular shield and the gladius. They were paired only against other provocatores.
