The Book of Enoch is an ancient Jewish religious work, traditionally ascribed to Enoch, the great-grandfather of Noah. It was first discovered in Africa (Ethiopia) in the mid 1700's and then also found among the Dead Sea Scrolls. 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. It is not part of the biblical canon as used by Jews, apart from Beta Israel. It is regarded as canonical by the Ethiopian Orthodox Church and Eritrean Orthodox Tewahedo Church, but no other Christian group. The older sections (mainly in the Book of the Watchers) are estimated to date from about 300 BC, and the latest part (Book of Parables) probably was composed at the end of the 1st century BC. It is wholly extant only in the Ge'ez language, with Aramaic fragments from the Dead Sea Scrolls and a few Greek and Latin fragments. For this and other reasons, the traditional Ethiopian view is that the original language of the work was Ge'ez, whereas non-Ethiopian scholars tend to assert that it was first written in either Aramaic or Hebrew; E. Isaac suggests that the Book of Enoch, like the Book of Daniel, was composed partially in Aramaic and partially in Hebrew. (Wikipedia)
