This medal depicts Charles V (1500-1558), who became Emperor of Spain in 1516 and Emperor of Gernany in 1519. On the reverse is Mary of Austria. It is by Peter Flötner (ca. 1485-1546). Flötner was a sculptor, medallist, cabinetmaker, woodcutter and designer. He worked initially in Augsburg from around 1512 to 1516 before moving to Nuremberg where he became a citizen in 1522. Changes in Flötner's style after around 1530 suggest he may have travelled to Italy. His workshop catered for bell-founders, goldsmiths, pewterers and medallists supplying them with plaques made of lead, tin, bronze and solnhofen limestone. They were used like pattern books. The plaques were arranged in lines and a clay or plaster mould was made from them. In these moulds wax models were cast which were then applied to the outside of the wax models of bells, mortars and tankards before they were cast in metal.
