The power of marvellous objects: Charles IV of Luxembourg, Charles V of Valois and their gemstones.

This paper explores the interest of Charles IV of Luxembourg (1316–1378), King of Bohemia and Holy Roman Emperor, in collecting gemstones, which has hitherto been little studied. It analyses this interest in connection with the fourteenth-century French royal court, and especially with the collecting activities of Charles V of Valois (1338–1380), King of France. Both of these sovereigns had an interest in ancient gems and they used them in the same manner; their practices prove to have been inspired by the reinvented traditions of the saintly Capetian monarch Louis IX, King of France, and of the ancient Roman Empire. This study shows how Charles of Luxembourg and Charles of Valois sought out and used precious and semi-precious stones as instruments of their royal self-images and claims to power.
