This book, written in honour of Mayke De Jong, offers twenty-five essays focused upon the importance of religion to Frankish politics. It deals with religious discourse and political polemic in studies that take up the themes of identity, and the creative deployment of the language of the Old Testament within Frankish society. The book explores how the use of ethnic rhetoric in a Christian context shaped medieval perceptions of community. It shows that the Carolingian way of dealing with the Adoptionist challenge was to allow a conversation between the Spanish bishops and their Frankish opponents to take place. Charlemagne's role in the Vita Alcuini as a guardian of orthodoxy who sought to settle a controversy by organising and supervising a theological debate was striking. The book also discusses the admonition of an abbot of Frankish origin who came from southern France and made his monastic career in southern Italy. It showcases three letter manuscripts that share certain features but are different in other aspects. The first manuscript is a collection of the Moral Letters from Seneca to his pupil Lucilius , Paris , BnF, lat. 8658A. The book demonstrates that the lists of amici, viventes et defuncti reflected how the royal monastery was interacting with ruling elites, at different levels, and how such interactions were an essential part of its identity. It also examines the context of Monte Cassino's fading into the background, in the conviction that both political and religious concerns were at play.
