The dimachaeri (singular: dimachaerus) were a type of Roman gladiator that fought with two swords (dual wield).
The name is a borrowing into Latin of Ancient Greek διμάχαιρος dimákhairos 'bearing two knives' (δι- di- 'two' + μάχαιρα mákhaira 'knife').
Some pictorial sources depict wearing extremely minimal such as a balteus and leather wrappings or none at all, save a subligaculum (loin cloth).
[1] A dimachaerus used a pair of sica (curved scimitar) or gladius and used a fighting style adapted to both attack and defend with his weapons rather than a shield, as he or she was not equipped with one.
[1] They are also referred to as fighting against a gladiator class called hoplomachus,[6] which, according to Justus Lipsius, was a putative variant of the Samnite.
