" Since the 1300s, this job had been performed by members of a small group of families, all living in the hills near the mine. Over the centuries humans grew larger, but the miners stayed the same size, until they eventually seemed dwarfed by the demands of the mine and their time underground (diet and inbreeding were more likely causes). Even in the early twentieth century, this small isolated community spoke a dialect last popular in the Middle Ages. They explored their tunnels with acetylene torches, and wore the white linen suits and peaked caps of medieval miners. "
