As regards the presentation of my material here, it has been my endeavour to make the argument intelligible to readers who are not classical scholars and archaeologists. The classics have ceased to be a water-tight compartment in the general scheme of study and research, and my subject forms a chapter in general economic history which might interest students of that subject who are not classical scholars. On the other hand classical studies have become so specialised and the literature in each department has multiplied so enormously that unless monographs can be made more or less complete in themselves and capable of being read without referring to a large number of large and inaccessible books, it will become impossible for classical scholars to follow the work that is being done even in their own subject beyond the limits of their own particular branch. For these reasons ancient authorities have been mainly given in literal English translations, and when, as happens in almost every chapter, information has to be sought from vases, coins, or inscriptions, I have tried to elucidate my point by means of explanatory descriptions and illustrations. The work has involved me in numerous obligations which I gladly take this opportunity of acknowledging. In 1907 I received grants from the Worts travelling bachelors’ fund of Cambridge University and from Gonville and Caius College to visit Greece for the purpose of collecting archaeological evidence upon the history of the early tyranny. This purpose was partially diverted because shortly after reaching Greece I became associated with the late Dr R. M. Burrows in the excavation of the Greek cemetery at Rhitsona in Boeotia and in the study and publication of the pottery found there. This pottery dates mainly from the age of the tyrants, and the results of my work at it appear in several of the succeeding chapters. To Dr Burrows I owe also the encouragement that led me to start working on the early tyranny: my main idea on the subject first occurred to me when I was lecturing on Greek history as his assistant at University College, Cardiff. I have also received much assistance at various times and in various ways from Professor G. A. T. Davies, another former colleague of mine at Cardiff, and from several of my Reading colleagues, particularly Professor W. G. de Burgh, Mr D. Atkinson, and my wife. Many other debts are recorded in the body of the book: but considering how many and various they have been, I can scarcely hope that none has been passed over without acknowledgement. But of all my obligations the earliest and chiefest is to Sir William Ridgeway. It is to the unique quality of his teaching at Cambridge that I owe the stimulus that suggested to me the explanation here offered of the origin of tyranny. P. N. URE.
