Rome’s mines were among the most productive and the most deadly operations in the ancient world. The silver mines of Spain, the gold mines of Dacia, the iron mines of Noricum, the lead mines of Britain, the copper mines of Cyprus — across the empire’s territories, Roman exploitation of mineral resources operated at a scale and intensity that would not be matched in Europe until the Industrial Revolution. The quantities extracted were enormous, the methods often technically sophisticated, and the human cost on the enslaved and condemned workforce was catastrophic in ways that the ancient sources acknowledge with varying degrees of discomfort.
