1 Enoch represents a merger of two different types of apocalyptic literature: the heavenly journey and the review of history. In both, the world is seen as disordered and in need of a divine reordering, which includes an imminent judgement. 1 Enoch is also likely three separate books that were later combined into a single book. It had widespread influence on both Jewish and Christian literature including the book of Revelation.
