Their hard and repetitive training also impacted their body shape, in some to the point of deformity.
According to the Latin writer Pliny, a gladiator called Studiosus, a Thraex belonging to the emperor Caligula, had a right arm longer than his left. Archaeology suggests that such asymmetry was not unique. A gladiatorial cemetery excavated in York in modern England contained eighty-two skeletons, of which seventy-four were young adult males. Of the later, one in seven had one arm more developed than the other. Like longbowmen in Medieval England, some gladiators were distinctively lopsided.
The equipment of a gladiator could also leave its mark. Sergius, a gladiator that the Roman satirist Juvenal claimed ran away with the wife of a senator, had a furrow on his forehead and a hump on his nose, caused by the rubbing of his helmet. Then there were the scars of their trade. Many of the skeletons from both Ephesus and York display evidence of sharp or blunt force trauma. Some of these wounds had healed. Most strikingly one gladiator from Ephesus, who presumably had retired from the arena to become a trainer, had survived the amputation of a leg.
What gave these bulky and scarred gladiators sex appeal was a potent mix of the dark glamour of violence and the thrill of transgression. Juvenal was clear about what attracted the senator’s wife to Sergius: “He was a gladiator, that makes each one an Adonis… it’s the steel they love.” The steel (ferrum) was his sword (gladius), and both were slang for penis. Gladiators were at the bottom of society. They were prisoners of war, criminals, slaves, and free men who had voluntarily reduced themselves to the status of slaves, swearing an oath “to be burned, bound, beaten, and killed with steel.”
Male writers thought that gladiators held a strong erotic appeal for elite women. A maid in Petronius’ 1st century AD novel The Satyricon says her mistress is one of those women whom the arena set on heat: what gave her pleasure was kissing the tracks of the whip.
