Across the ancient and medieval literature of Judaism, Christianity, and Islam, one finds references to the antediluvian sage Enoch. Both the Book of the Watchers and the Astronomical Book were long known from their Ethiopic versions, which are preserved as part of Mashafa Henok Nabiy (‘Book of Enoch the Prophet’)–an Enochic compendium known in the West as 1 Enoch. Since the discovery of Aramaic fragments among the Dead Sea Scrolls, these books have attracted renewed attention as important sources for ancient Judaism. Among the results has been the recognition of the surprisingly long and varied tradition surrounding Enoch. Within 1 Enoch alone, for instance, we find evidence for intensive literary creativity. This volume provides a comprehensive set of core references for easy and accessible consultation.
