Medieval wheelpit at Huntingdon mine on southern Dartmoor. Without tin there would have been no Bronze Age. Tin is rare in Europe. The earliest and largest center for tin mining in Europe dates to 2500 BCE in Erzgebirge in the Balkans. It was in huge demand and exported as far as the Mediterranean. Other sources of tin in Europe were mined in Devon and Cornwall in England, Brittany in France, the Iberian Peninsula and a tiny amount in Italy used by the Etruscans.
Miner Boy: Children were cheap labor in the mines. This boy spent 10 hours a day in that outfit with only the light from that tallow wick lamp. He cleaned played the part of a "canary" (kids were easier to replace than good miners). He was probably Finnish or Swedish indentured to the company for the purpose of paying his fathers debts. The unions fought bloody battles to get these children out of the coal mines. This little guy worked ( likely died) in Utah or Colorado mines / Scott Cooper
