Gold Coinage in the Roman World

Lead Research Organisation: University of Warwick
Department Name: Classics & Ancient History

Abstract

A study of the metallurgy and circulation of Roman gold coinage that aims to define its significance within Roman society and the Roman economy. Analyses drawn from the 600 Roman gold coins in the Ashmolean have the potential to provide the basis on which the history of Roman gold coinage will be interpreted in the future. The Coin Hoards of the Roman Empire Project can provide the necessary data on coin circulation and online tools for analysis. The thesis will address major historical questions through a study of the weight standards, gold standards and circulation and hoarding of Roman gold coinage. The fineness of Roman gold appears remarkably stable, with minor blips only in the mid-third and mid-fourth centuries, unlike the silver coinage, the dramatic decline of which has been regarded as an indicator of the fiscal inadequacy of the Roman Empire. This has always been a conundrum, which this study will seek to resolve. The metal analyses will investigate not only fineness but also metal sources and metal flows, drawing on new approaches developed by Butcher at Warwick and by Pollard and Bray in Oxford. Other areas for investigation are the point at which gold coin ceased to circulate at a fixed nominal value and became more like a circulating ingot and the suggestion that there was a major new source of gold in the fourth century.With the additional evidence for circulation it will become possible to create a more rounded account of the role of gold coin within the Roman economy. The idea that the apparent scarcity of gold in the third century was due to export from the Empire, most importantly through subsidies paid to 'barbarians', requires testing. In terms of function, the initial provision of gold to the military in the early empire is evident, but what happened after that is much less clear. By the fourth century AD control of gold appears to have been both a marker of, and a means to enhance, social hierarchy throughout the provinces. How did this change come about?

Description So far: The project has been given a small exhibition at the Ashmolean museum to begin in 2020. (Culture, heritage, museums and collections) I am part of a three person team from Warwick that won a panel session at the British science festival 2019. The successful session has a working title of 'The Science of Money'. The festival seeks to link the public with scientists, engineers and technologists, and so is not purely academic. (Other)

PI Contribution Roman gold and silver coins have been analysed using negative muons. For the silver coins I helped to conduct the negative muon experiment and contributed to the archaeological analysis of the chemical data produced - this has been published in the journal 'Heritage' For the gold coins I spent multiple days conducting the experiment alongside the muon group and took the lead in providing the numismatic, historical and archaeological analysis of the data produced. I also designed a new project on the gold coinage of the AD 69 Civil wars and submitted this proposal to the facility for beam team - it was ranked as 'must be done' and is due to commence in September 2020
Collaborator Contribution The Muon group, lead by Dr Adrian Hillier, provided invaluable scientific and technical expertise - not least the ability to run the particle accelerator and interpret the primary data produced by the interaction of negative muons with the coins analyses. Access to ISIS was facilitated by Dr Hillier.

Results and Impact A 6 month exhibition based on my research will feature in the Ashmolean Museum's Money Gallery from March 2020 until August 2020. It is entitled Lasers, Hoarding and Roman Gold Coinage, and seeks to explain to the general public what has been discovered as part of my Doctoral research. The exhibition is free to all visitors to the museum and contains the gold coins sampled as part of my chemical analyses, as well as some of the equipment used during the experiments.
