Mine Pumping in Agricola's Time and Later

Mine Pumping in Agricola's Time and Later

Coins are a source of information much used by historians. Elaborately detailed mining landscapes on 16th-century German coins in the National Museum, discovered by the curator of numismatics and brought to the authors attention, led to this study of early mine-pumping devices. The habit of heavy reliance on a single source for the substance of the history of Medieval and Renaissance mining techniques in Europe has led to a rather drastic over-simplification of that history, a condition which persists tenaciously in the recent accounts of Parsons, Wolf, and Bromehead.[1] Our preoccupation with Agricola, who has been well known to the English-language public since the Hoovers translation of 1912, seems to have inhibited the investigation of the development of the machines he describes so elegantly. More seriously, the opinion that mining techniques remained essentially the same for a century or two beyond his time appears to have hardened into a conviction.[2] The history of the technology of mining, as distinguished from metallurgy, is largely a history of mechanization, and that mechanization has until the last century consisted principally in the development of what Agricola calls tractoriaehauling machines. That hauling machines of some complexity, Archimedian screws and a kind of noria, were used by the Romans for dewatering mines has been known for some time. Evidence of the survival of this technology beyond the fall of Rome remains to be found, and it is generally agreed that mining activity declined through the first millenium. The revival and extension of mining in the central European areas of German settlement is thought to have occurred from the 10th century, with an intensive development of the region known to Agricola (Erzgebirge) in the 13th century.[3] ......Buy Now (To Read More)
