This volume contains five chapters which investigate the early Christian appropriations of Jewish apocalyptic material. An introductory chapter surveys ancient perceptions of the apocalypses as well as their function, authority, and survival in the early Church. The second chapter focuses on a specific tradition by exploring the status of the Enoch-literature, the use of the fallen-angel motif, and the identification of Enoch as an eschatological witness. Christian transmission of Jewish texts, a topic whose significance is more and more being recognized, is the subject of chapter three which analyzes what happened to 4,5 and 6 Ezra as they were copied and edited in Christian circles. Chapter four studies the early Christian appropriation and reinterpretation of Jewish apocalyptic chronologies, especially Daniel's vision of 70 weeks. The fifth and last chapter is devoted to the use and influence of Jewish apocalyptic traditions among Christian sectarian groups in Asia Minor and particularly in Egypt. Taken together these chapters written by four authors, offer illuminating examples of how Jewish apocalyptic texts and traditions fared in early Christianity.
