Roman slavery was a brutal institution marked by pervasive violence, dehumanization, and exploitation, according to a recent detailed historical examination. Contrary to common images of slaves as mere household servants, many were subjected to harsh conditions ranging from deadly labor in remote quarries and mines to exploitation in the arena and sex slavery.

One stark example is the quarry of Mons Porphyrites in Egypt, a heavily fortified site where slaves labored under severe desert heat to extract red porphyry stone prized by the Roman elite. The area was closely guarded with numerous watchtowers and checkpoints, reflecting the high security necessary for such an operation. Slaves working here were unlikely to survive for long. Similarly, in Wales, slaves endured grueling hours walking on treadmills to pump water from deep gold mines, a condition likened to the forced labor seen in Soviet camps.

The Roman state’s persistent wars fueled its need for slave labor. After the capture of Cartagena in Spain in 209 BC, the Roman army enslaved thousands of prisoners, assigning the strongest men to deadly conditions such as galley rowing, a virtual death sentence. When Jerusalem fell in AD 70, prisoners were paraded during triumphal celebrations, worked to death in quarries, or killed in public spectacles. Such events were widely accepted as entertainment with no recorded Roman criticism.

Slave owners routinely inflicted physical abuse. Punishments ranged from beatings, often leaving slaves with broken bones or injured hands, to more severe mutilations aimed at controlling or disabling captives without ending their productivity. Some were blinded or had tendons burned out to prevent escape or rebellion. These acts underscore not only the cruelty but also the persistent resistance by enslaved individuals, as documented by complaints from Roman masters about defiance and laziness.

Sexual exploitation was a widespread, normalized aspect of slavery. Since slaves were considered property, their bodies were subject to owners’ desires. Gladiators, mostly slaves themselves, were often sexually exploited, a fact that complicates the romanticized image of their lives. Evidence from brothels, including one in Ostia named after Jupiter and Ganymede, suggests that child prostitution, including of boys, was common and accepted. Ancient texts describe methods to inhibit puberty or castrate boys to maintain their sexual availability.

Many slaves, facing these brutal realities, chose death over captivity, but the historical record has largely erased their identities, save a few detailed price records. The anonymity of millions of enslaved individuals contrasts sharply with the vivid details of their suffering uncovered in recent research.

The persistence of such cruelty, despite contemporary religious teachings advocating compassion, highlights how deeply embedded slavery was within Roman society. The institution was so pervasive that few dared to imagine a world without it. The study draws parallels between ancient acceptance of extreme violence and modern social practices that may one day be judged as harshly. The grim legacy of Roman slavery serves as a reminder of the social norms that can blind societies to pervasive injustice.
