This volume collects thirty essays by Shaye J.D. Cohen. First published between 1980 and 2006, these essays deal with a wide variety of themes and texts: Jewish Hellenism; Josephus; the Synagogue; Conversion to Judaism; Blood and Impurity; the boundary between Judaism and Christianity. What unites them is their philological orientation. Many of these essays are close studies of obscure passages in Jewish and Christian texts. The essays are united too by their common assumption that the ancient world was a single cultural continuum; that ancient Judaism, in all its expressions and varieties, was a Hellenism; and that texts written in Hebrew share a world of discourse with those written in Greek. Many of these essays are well-known and have been much discussed in contemporary scholarship. Among these are: The Significance of Yavneh (the title essay), Patriarchs and Scholarchs, Masada: Literary Tradition, Archaeological Remains, and the Credibility of Josephus, Epigraphical Rabbis, The Conversion of Antoninus, Menstruants and the Sacred in Judaism and Christianity, and A Brief History of Jewish Circumcision Blood.

In ancient Jewish culture the ideas of purity and impurity defined the socio-cultural boundaries between Jews and Gentiles. Hayes argues that different views of the possibility of conversion, based on varying ideas about Gentile impurity, were the key factor in the formation of Jewish sects in the second temple period, and in the separation of the early Christian Church from what later became rabbinic Judaism.

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.

Since the late 1700s, when the Jewish community ceased to be a semiautonomous political unit in Western Europe and the United States and individual Jews became integrated-culturally, socially, and politically-into broader society, questions surrounding Jewish status and identity have occupied a prominent and contentious place in Jewish legal discourse. This book examines a wide array of legal opinions written by nineteenth- and twentieth-century orthodox rabbis in Europe, the United States, and Israel. It argues that these rabbis' divergent positions-based on the same legal precedents-demonstr.
