This book is a detailed study of Hugh of Flavigny and his chronicle, which is widely recognised as one of the most important narratives of a crucial period of European history, that is, the Investiture Contest. Hugh's Chronicon is significant in a number of ways: as a unique source-book for some of the most important primary documents (especially papal letters) generated by the Investiture Contest; as a rare autograph manuscript which gives an important insight into contemporary modes of composition and compilation; as an important history of the 'local' effects of the Investiture Contest in the dioceses of Verdun and Autun; and as a striking autobiography of the author, Hugh of Flavigny. All these aspects are covered in this study by Patrick Healy. Other chapters investigate the context of the work in terms of ecclesiastical politics and use an analysis of the political and theological sources to illustrate the intellectual make-up of a contemporary monk, publicist - and polemicist.
