The sale of indulgences became an industry only in Luther’s own lifetime and in his own lands, put into place by the “warrior Pope” Julius II and the Augsburg banker Jakob Fugger. After 1506, pope and banker directed the revenue from German indulgences toward the rebuilding of Saint Peter’s in Rome. These heavy wooden boxes with their multiple locks demonstrate the extent to which the German states were exporting huge quantities of metal to Rome and receiving printed slips of paper in return, exchanging material wealth for the equivalent of checks that drew on the currency of heaven rather than earth. Jakob Fugger took a 3 percent cut—in coins, not release from Purgatory—on every shipment south. Is it any wonder that the man who finally pulled the plug on this improbable trade knew a thing or two himself about the value of metal?
Το a remarkable extent, as these exhibitions reveal, Luther’s world, and Luther’s Reformation, revolved around metal. The silver, copper, lead, and iron mined from the Harz Mountains and smelted in small-scale factories like Hans Luder’s copper works took up only a corner of an international market in which Jakob Fugger was one of the most aggressive participants. Fugger may have been shipping coins by the cofferful to the pope in Rome, but metal was also flowing into his own treasury from his silver and copper mines in Tyrol and Bohemia.
