The first part of the Book of Enoch describes the fall of the Watchers, the angels who fathered the Nephilim. The remainder of the book describes Enoch's visits to heaven in the form of travels, visions and dreams, and his revelations. The book consists of five quite distinct major sections (see each section for details): Most scholars believe that these five sections were originally independent works (with different dates of composition), themselves a product of much editorial arrangement, and were only later redacted into what we now call 1 Enoch.
