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').
The dimachaeri were popular during the 2nd to 4th centuries CE, and were probably considered to be "insidious" by many Romans.[1] Both written and pictorial records on dimachaeri are scant and rather indeterminate.[2] Thus, an inscription from Lyon, France, mentions such a type of gladiator, here spelled dymacherus.[3]
