Leading scholars explore the tradition, rooted in Genesis 6, of "the Watchers," mysterious heavenly beings who became the focus of rich cosmological and theological speculation in early Judaism. Chapters trace the development of the Watchers through the Enoch literature, Jubilees, and other early Jewish and Christian writings.

At the origin of the Watchers tradition is the single enigmatic reference in Genesis 6 to the sons of God who had intercourse with human women, producing a race of giants upon the earth. That verse sparked a wealth of cosmological and theological speculation in early Judaism. Here leading scholars explore the contours of the Watchers traditions through history, tracing their development through the Enoch literature, Jubilees, and other early Jewish and Christian writings. This volume provides a lucid survey of current knowledge and interpretation of one of the most intriguing theological motifs of the Second Temple period.
