Book of Enoch

Anonymous, traditionally attributed to Enoch

(also 1 Enoch; Ge'ez: መጽሐፈ ሄኖክ mätṣḥäfä henok), ancient Jewish religious work, ascribed by tradition to Enoch, the great-grandfather of Noah, although modern scholars estimate the older sections (mainly in the Book of the Watchers) to date from about 300 BC, and the latest part (Book of Parables) probably to the first 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 belief 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; Ephraim Isaac suggests that the Book of Enoch, like the Book of Daniel, was composed partially in Aramaic and partially in Hebrew. No Hebrew version is known to have survived.
