A new account of the role of coinage in the finances and economy of the Roman Empire.

​This edited volume examines metallurgical technologies and their place in society throughout the centuries. The authors discuss metal alloys and the use of raw mineral resources as well as fabrication of engineered alloys for a variety of applications. The applications covered in depth include financial, mining and smelting, bridges, armor, aircraft, and power generation. The authors detail the multiple levels and scales of impact that metallurgical advances have had and continue to have on society. They include case studies with guidance for future research design and innovation of metallic materials relevant to societal needs. Includes case studies written by industry professionals with guidance for future research design and innovation; Demonstrates metal materials design that reflects relevant societal needs; Covers a broad range of applied materials used in aircraft, armor, bridges, and power generation, among others.

The fineness of Roman imperial and provincial coinage has been regarded as an indicator of the broader fiscal health of the Roman Empire, with the apparent gradual decline of the silver content being treated as evidence for worsening deficits and the contraction of the supply of natural resources from which the coins were made. This book explores the composition of Roman silver coinage of the first century AD, re-examining traditional interpretations in the light of an entirely new programme of analyses of the coins, which illustrates the inadequacy of many earlier analytical projects. It provides new evidence for the supply of materials and refining and minting technology. It can even pinpoint likely episodes of recycling old coins and, when combined with the study of hoards, hints at possible strategies of stockpiling of metal. The creation of reserves bears directly on the question of the adequacy of revenues and fiscal health.

In the years covered by this volume, 1250-1450, the production patterns, in both the European precious and base metal industries, first established in the twelfth century, and described in volume two, continued to be played out. This now took place however in the context of a continuous process of increasingly acute resource depletion, which finally culminated in the terminal mining crisis of the 1450s. Even as European silver production declined, however, compensatory supplies of precious metals became for the first time available as a counter-cyclical production pattern came to characterise a newly emergent European gold industry which by 1450 had displaced African gold as the main source of supply to European mints. African gold increasingly was supplied to African and Asiatic markets. Vol. I: Asiatic Supremacy, 425-1125 Vol. 2: Afro-European Supremacy, 1125-1225 .
