In this volume Gabriele Boccaccini and Jason M. Zurawski collect together essays from leading international scholars on the books of 4 Ezra and 2 Baruch. The literature of the Second Temple Period has become increasingly studied in recent years as scholars have begun to recognize the importance of these texts for a developed understanding of Rabbinic and Christian origins. Through close readings of the texts themselves, examining the books in comparison with other Jewish apocalyptic literature and early Christian materials, and reading the texts in light of their social and historical settings, the fifteen papers collected herein significantly advance the current scholarly conversation on these defining Jewish apocalypses written at the end of the first century CE, and they shed light on the everlasting legacy of apocalyptic ideas in both Christianity and Judaism.
