A critical edition of the four Aramaic manuscripts from Qumran (4Q208-4Q211) that comprise the Aramaic Astronomical Book, part of the Jewish pseudepigraphic literature of the Second Temple period. It describes the movement of the moon in its phases, schematic meteorology, and the movement of the stars in relation to the seasons of the year.

The ancient mathematical basis of the Aramaic calendars in the Dead Sea Scrolls is analysed in this investigation. Helen R. Jacobus re-examines an Aramaic zodiac calendar with a thunder divination text (4Q318) and the calendar from the Aramaic Astronomical Book (4Q208 - 4Q209), all from Qumran. Jacobus demonstrates that 4Q318 is an ancestor of the Jewish calendar today and that it helps us to understand 4Q208 - 4Q209. She argues that these calendars were taught in antiquity as angelic knowledge described in 1 Enoch and the Book of Jubilees. The study also encompasses Babylonian, Hellenistic, Byzantine astronomy and astrology, and classical and Jewish writings. Finally, a medieval Hebrew zodiac calendar related to 4Q318 with an astrological text is published here for the first time.

Rather than being an isolated, primitive body of knowledge the Jewish calendar tradition of 364 days constituted an integral part of the astronomical science of the ancient world. This tradition—attested in the Dead Sea Scrolls and in the Pseudepigrapha—stands out as a coherent, novel synthesis, representing the Jewish authors’ apocalyptic worldview. The calendar is studied here both “from within”—analyzing its textual manifestations —and “from without”—via a comparison with ancient Mesopotamian astronomy. This analysis reveals that the calendrical realm constituted a significant case of inter-cultural borrowing, pertinent to similar such cases in ancient literature. Special attention is given to the “Book of Astronomy” (1 Enoch 72-82) and a variety of calendrical and liturgical texts from Qumran.

A new explanation of the beginnings of Jewish angelology and demonology, drawing on non-canonical writings and Aramaic Dead Sea Scrolls.

In Hellenistic Astronomy: The Science in Its Contexts, renowned scholars address questions about what the ancient science of the heavens was and the numerous contexts in which it was pursued.

This book provides the first comprehensive treatment of the Aramaic Dead Sea Scrolls from the caves of Qumran. These nearly one hundred scrolls open a window onto a vibrant period of Jewish history for which we previously had few historical sources. Scholars and advanced students will find a general introduction to the corpus, detailed, richly-illustrated profiles of individual scrolls, and up-to-date studies of their Aramaic language and scribal practices. The goal of the book is to foster and support further study of these scrolls against the historical backdrop of early Judaism and ancient Mediterranean scribal cultures.

This volume contains studies that explore the content and meaning of the Qumran manuscripts of the Aramaic Books of Enoch, the Book of Giants, and related literature. The essays shed new light on the lexicon, orthography and grammar of the Aramaic scrolls, as well as their relationship to schematic astronomy in ancient Mesopotamia. Contributors examine the origin of the angelic tradition of the Watchers, the textual and literary relationship of the Aramaic scrolls to the Book of the Watchers, and the culpability of humanity in the spread of evil on earth according to the myth of the fallen angels.

The fragments of Aramaic Levi Document are presented for the first time as a single coherent whole. This book, which will move the study of this pivotal document to a new level, includes original texts, translation, introduction and extensive and detailed commentary.

This work explores the tension between the hegemony of central scientific traditions and local scientific enterprises, showing the relevance of ancient data to contemporary postcolonial historiography of science.
