The Book of Enoch is one of the so-called Old Testament Pseudepigrapha, which was widely used in the ancient Church, and is quoted in the Epistle of Jude, 14 sq. The work disappeared after about the fifth century, and was supposed to have perished (with the exception of a few fragments) until in 1773 it was discovered entire in an Ethiopic Bible, and in 1838 was published in Ethiopic by Lawrence, who in 1821 had already translated it into English. Dillmann also published the Ethiopic text in 1851, and in 1853 a German translation with commentary. Dillmann’s edition of the original entirely supersedes that of Lawrence, and his translation and commentary still form the standard work upon the subject. More recently it has been re-translated into English and discussed by George H. Schodde: The Book of Enoch, translated, with Introduction and Notes, Andover, 1882. The literature on the book of Enoch is very extensive. See especially Schodde’s work, the German translation of Dillmann, Schürer’s Gesch. der Juden, II. p. 616 sq., and Lipsius’ article, Enoch, Apocryphal Book of, in the Dict. of Christ. Biog. The teachings of the book to which Anatolius refers are found in the seventy-second chapter (Schodde’s ed. p. 179 sq.), which contains a detailed description of the course of the sun during the various months of the year.
