Leading scholars from Italy and the United States offer a fresh and nuanced image of the religious reform movements on the Italian peninsula in the sixteenth and seventeenth centuries. United in their conviction that religious ideas can only be fully understood in relation to the particular social, cultural, and political contexts in which they develop, these scholars explore a wide range of protagonists from popes, bishops, and inquisitors to humanists and merchants, to artists, jewelers, and nuns. What emerges is a story of negotiations, mediations, compromises, and of shifting boundaries between heresy and orthodoxy. This book is essential reading for all students of the history of Christianity in early modern Europe.
