This book was lost for centuries to the western world, although it was kept by the Ethiopian church. In 1773, the Scottish explorer James Bruce heard that the Book of Enoch may have been in Ethiopia, so he traveled there and procured three copies. In 1821, Richard Laurence, a professor of Hebrew at Oxford, produced the first English translation. Fragments of ten Enoch manuscripts were found among the Dead Sea Scrolls. It is quoted by the New Testament Book of Jude.

This book contains all sections:
The Book of the Watchers
The Book of Parables of Enoch
The Astronomical Book
The Book of Dream Visions
The Epistle of Enoch

The Lost Book of Enoch is especially interesting to anyone with an interest in angels and demons, or Bible history in general.
