Mercury in gold mining

"There was a method by which the mercury was shaken up with material containing gold ore, dissolved, and squeezed through a piece of leather. This is probably the origin of the story about Jason and the Golden flits. The gold mines in Asia Minor used that, and the Flits were golden flits."

Mercury and environmental consciousness

"People died, not that they cared very much; life was cheap in the Roman Empire. But the Emperor Hadrian had some humanitarian impulses along those lines. They tried to limit the hours of exposure of miners to mercury, prescribing showers, washing clothes, and so on."
