'The Persian Empire has never been out of the news, but since the great British Museum exhibition, and a spate of publications on the subject, it is more in the eyes and minds of archaeologists and historians of the ancient world than hitherto. This welcome volume offers a major guide to and an explanation of the whole phenomenon, from the acknowledged experts. It will be used and referred to more than most such compendia, and for very good reason.' - Sir John Boardman, FBA, Lincoln Professor Emeritus of Classical Art and Archaeology, University of Oxford.
