De Re Metallica brings together a wide variety of perspectives on metal use in the Middle Ages, a topic that has received less systematic scholarly attention than it deserves, given its central importance for medieval culture. Because of its strength, beauty, and prestige, metal figured prominently in many medieval contexts, from the military and utilitarian to the architectural and liturgical. Metal was a crucial ingredient in weapons and waterpipes, rose windows and reliquaries, coinage and jewelry. The 23 essays presented here, from an international team of scholars, explore the production and use of such objects, from the early Middle Ages to the sixteenth century, and from the British Isles, Iceland, and Scandinavia, to France, Germany, Spain and Italy. This thematic, chronological, and geographical scope will make this volume into a valuable resource for historians of art, technology, and culture.
