During the sixteenth-century reform movement, Zwingli and his humanist colleagues in Zurich sought biblical, historical, literary, and political models to shape and defend their radical reforms. This book explores history, scholarship, and memory and examines the immediacy of antiquity, early Christianity, and the Middle Ages for the Zurich reformers after Zwingli's death. The interplay of past ideals with the pressing demands of a sixteenth-century reform movement tells us a great deal not only about Zwinglianism but also about locality, history and religious change in the European Reformatio.
