This volume deals with conversions to Judaism from the 16th to the 18th century. It provides six case studies by leading international scholars on phenomena as crypto-Judaism, "judaizing", reversion of Jewish-Christian converts and secret conversion of non-Jewish Christians for intellectual reasons. The first contributions examine George Buchanan and John Dury, followed by three studies of the milieu of late seventeenth-century Amsterdam. The last essay is concerned with Lord George Gordon and Cabbalistic Freemasonry. The contributions will be of interest for intellectual historians, but also historians of political thought or Jewish studies.

Contributors include: Elisheva Carlebach, Allison P. Coudert, Martin Mulsow, Richard H. Popkin, Marsha Keith Schuchard, and Arthur Williamson.
