Smith's Bible Dictionary (1863)
The first trance of the existence of this work is found in the Epistle of (Jude 1:14,15) An apocryphal book called Enoch was known at a very early date, but was lost sight of until 1773, when Bruce brought with him on his return from Egypt three MSS. containing the complete Ethiopic translation. In its present shape the book consists of a series of revelations supposed to have been given to Enoch and Noah, which extend to the most varied aspects of nature and life. And are designed to offer a comprehensive vindication of the action of Providence.
Notwithstanding the quotation in Jude, and the wide circulation of the book itself, the apocalypse of Enoch was uniformly and distinctly separated from the canonical Scriptures. Its authorship and date are unknown.
