This volume represents the culmination of three decades' work on the Book of 1 Enoch for George W.E. Nickelsburg. He provides detailed commentary on each passage in chapters 1-36 and 81-108, and an introduction to the full work. The introduction includes sections on overviews of each of the smaller collections, texts and manuscripts, literary aspects, worldview and religious thought, the history of ideas and social contexts, usage in later Jewish and Christian literatures, and a survey of the modern study of the book.
