Then having made a well-fitted cover and having laboriously smeared it over with mud, they bake it in kilns for five days and as many nights continuously. Then after letting it cool, they find none of the other things in the vessels, but get the gold in a pure state with but a slight reduction in quantity. With so many and so great sufferings is the production of gold at the frontiers of Egypt completed. For Nature herself makes it plain, I think, that gold is produced with toil, is guarded with difficulty, is most eagerly sought for, and is enjoyed with mixed pleasure and pain. The discovery of these mines is of very ancient date, inasmuch as it was made known by the ancient kings39.”
Such then is the vivid picture drawn by the humane Diodorus of the horrible torments of the unhappy bondsmen who worked these famous mines, sufferings only to be paralleled by the miseries endured by the miners in Spain under Roman rule, by the Indians in the mines of Peru under the yoke of the Spaniard, and by the helpless sufferers under Muscovite cruelty who at this hour endure a living death in the mines of Siberia.
