These eleven essays, written by leading experts in the field, focus on norms of canon law, including norms of Romano-canonical procedure in the ius commune, as well as exchanges or cross-influences between different systems of law (e.g., between canon and Roman law, between canon and English common law, or between medieval canon law and early modern laws of nation-states). They treat particular concepts, influences, maxims, procedures, modes of inquiry and analysis in both Catholic and Protestant thought. Essays in this volume contribute to a geographically and temporally broadunderstanding of the legal culture of the later medieval and early modern period, from roughly 1150 to 1800, and the place of medieval canon law within it. The value of these works lies in their revealing new directions in the field, reinterpretations of well-trodden territory, fascinating case studies, and the latest discoveries concerning texts, jurists, and manuscripts in the history of medieval canon law.
