This volume contains seven Aramaic manuscripts of a Jewish pseudepigraphic tradition from the Second Temple period that ascribes to Enoch, the biblical antediluvian patriarch, a series of heavenly revelations and visions. 4Q201, 4Q202, 4Q204, 4Q205, 4Q206, 4Q207, and 4Q212 published here partially overlap with the Book of the Watchers, the Book of Dreams, and Letter of Enoch and constitute the earliest textual witness to these pseudepigrapha. The fragmentary Aramaic text is accompanied by a paleographic description, grammatical and textual notes, reconstructions, and synoptic comparison with versional evidence. The Aramaic, Aramaic-Greek, and Greek-Aramaic concordances are based on the Aramaic text collated anew for the present edition. The book also comprises an edition of two Greek excerpts, together with a Latin and Syriac fragment of 1 Enoch.
