The Achaemenid Empire was huge and the material available for studying it is disparate. The coinages produced in the empire offer distinctive perspectives and provide insights into crucial questions about how the empire was organised and administered. The numismatic evidence is particularly important due to its first hand, contemporary nature: it speaks to us directly, not through the prism of later accounts. Keith Rutter, an international specialist in numismatics, provides us with the first comprehensive account of the great variety of coinages produced in the Achaemenid Empire. He shows us how the iconography found on coins poses new questions on artistic influences, details of administration and religious beliefs. This highly illustrated book is the starting point for anyone who wants to understand the topic.
