The murmillo (also sometimes spelled "mirmillo" or "myrmillo", pl. murmillones) was a type of gladiator during the Roman Imperial age. The murmillo-class gladiator was adopted in the early Imperial period to replace the earlier Gallus, named after the warriors of Gaul. As the Gauls inhabiting Italy had become well-integrated with the Romans by the time of the reign of Augustus, it became undesirable to portray them as enemy outsiders; the Gallus-class gladiator thus had to be retired.
The murmillo was armed with:
The murmillo usually fought the thraex or hoplomachus, with whom he shared some of the equipment (notably arm guards and all-enclosing helmet, and the dangerous short sword). A number of ancient authors, including Valerius Maximus and Quintillian, assert that he also regularly fought the retiarius. It would certainly have been an unusual pairing, contrasting a slow but heavily armoured gladiator with a fast but lightly equipped one. This pairing is disputed; visual depictions of murmillones usually show them fighting the thraex or hoplomachus rather than the retiarius. However, Channel 4's Time Team discovered in Wales a carved penknife handle depicting a retiarius and a murmillo fighting.Furthermore, the TV documentary series The Supersizers Eat also describes the retiarius vs murmillo as a depiction of fishermen catching fish.
The murmillo's fighting style was suited for men with large muscular arms and strong heavy shoulders needed to carry the weight of the shield and sword. Men who fought as murmillones were usually big tall men and always very muscular. The murmillo depended on his strength and endurance to survive the battle against foes who were more suited to attacking. The tower shield gave him an edge in defense and the gladius enabled him to thrust and swing at his enemies when in close range. The murmillones were also trained to kick their enemies with the thick padding worn around their legs.
