Book excerpt: Between Sword and Prayer is a broad-ranging anthology focused on the involvement of medieval clergy in warfare and a variety of related military activities. The essays address, on the one hand, the issue of clerical participation in combat, in organizing military campaigns, and in armed defense, and on the other, questions surrounding the political, ideological, or religious legitimization of clerical military aggression. These perspectives are further enriched by chapters dealing with the problem of the textual representation of clergy who actively participated in military affairs. The essays in this volume span Latin Christendom, encompassing geographically the four corners of medieval Europe: Western, East-Central, Northern Europe, and the Mediterranean.
