In the wake of the split of the western Christian Church in the sixteenth century, the meaning of the notion ‘conversion’ received new interest in Europe. In recent years research into early modern practices of conversion, their narratives and imagery has broadened, benefiting from anthropological, psychological and linguistic approaches. This volume aims to build upon this growing scholarship and to evaluate its merits. Notably, it concentrates on what it calls ‘intra-chrétiennes’ patterns of conversion in the sixteenth and seventeenth centuries, thus excluding Islamic or Jewish experiences and European encounters with belief systems in the Americas, Asia and Africa. The collection opens with an extensive and helpful introduction by Daniela Solfaroli Camillocci, which also serves as a summary of the different articles. The first group of essays, by Irena Backus, Paul-Alexis Mellet, Keith Luria and Adelis Malena, is concerned with the spiritual meanings of conversion to individual believers in the Reformation period, assessing what biblical, patristic or literary models were available to them and how these were adapted to suit contemporary concerns. The second part of the volume, which includes articles by Nicolette Mout, Nicolas Fornerod, Susan Rosa and Maria-Cristina Pitassi, focuses on controversies that surrounded the conspicuous ‘conversions’ of high profile figures, including Justus Lipsius and Christina of Sweden. The third part, featuring contributions by Alain Tallon, Bernard Dompnier, Irene Fosi and Christian Grosse is more mixed in scope and includes discussions of the role of ritual, the Inquisition and the problem of institutional source material in general. The collection has grown out of an international conference at the Institut d'histoire de la Réformation in Geneva. In the spirit of its eminent international tradition, the book includes essays in English, French and Italian.
