Calendar and Community traces the development of the Jewish calendar from its origins until it reached, in the tenth century CE, its present form. Drawing on a wide range of often neglected sources - literary, documentary, epigraphic, Jewish, Graeco-Roman and Christian - it is the first comprehensive work to have been written on the subject. It will be useful not only to historians and epigraphists for the interpretation of early Jewish datings, but also as a historical study of early Judaism in its own right. Its main theme is that the Jewish calendar evolved in the course of this period from considerable diversity (with a variety of solar and lunar calendars) to unity (with the normative rabbinic calendar). The unification of the calendar was one element in the unification of Jewish identity in later antiquity and the early medieval world.

Calendars were at the heart of ancient culture and society, and were far more than just technical, time-keeping devices. Calendars in Antiquity offers a comprehensive study of the calendars of ancient Mesopotamia, Egypt, Persia, Greece, Rome, Gaul, and all other parts of the Mediterranean and the Near East, from the origins up to and including Jewish and Christian calendars in late Antiquity. In this volume, Stern sheds light on the political context in which ancient calendars were designed and managed. Set and controlled by political rulers, calendars served as expressions of political power, as mechanisms of social control, and sometimes as assertions of political independence, or even of sub-culture and dissidence.While ancient calendars varied widely, they all shared a common history, evolving on the whole from flexible, lunar calendars to fixed, solar schemes. The Egyptian calendar played an important role in this process, leading most notably to the institution of the Julian calendar in Rome, the forerunner of our modern Gregorian calendar. Stern argues that this common, evolutionary trajectory was not the result of scientific or technical progress. It was rather the result of major political and social changes that transformed the ancient world, with the formation of the great Near Eastern empires and then the Hellenistic and Roman Empires from the first millennium BC to late Antiquity. The institution of standard, fixed calendars served the administrative needs of these great empires but also contributed to their cultural cohesion.

This illuminating study is about the absence of a concept of time in ancient Judaism, and the predominance instead of process in the ancient Jewish world-view. Sacha Stern draws his evidence from the complete range of Jewish sources from this period: mainly early rabbinic literature, but also Jewish Hellenistic literature, Qumran sources, Apocrypha and Pseudepigrapha, and inscriptions.Following a methodological introduction drawing on anthropological studies, the author starts by focusing on the word used for time in early rabbinic literature, zeman. He shows that it means only ‘points in time’ or finite periods of time, but that the concept of time as a continuum—of time as a whole—is totally absent from rabbinic texts. It is unknown even in such obvious contexts as discussions of age, accounts of the creation of the universe, and in other matters relating to timing and time reckoning, the calendar, and chronology. He shows convincingly that although timing was central to early rabbinic halakhah, it was not conceived of as a measuring of the time dimension, but rather as a way of co-ordinating different processes (e.g. co-ordinating the reading of the Shema with sunrise or dusk). The calendar, likewise, was not a measurement of time but an astronomical scheme, and therefore only process-related. Similar conclusions apply to early rabbinic notions of chronology, history, and even ethics: the notion of time as an entity or a resource, so familiar in modern society, is completely unknown in rabbinic ethics.Further confirmation emerges from the author's study of non-rabbinic ancient Jewish sources in Greek, Hebrew and Aramaic, including Apocryphal and Pseudepigraphic works and Dead Sea Scrolls, sources that are also concerned with the calendar and chronology but without any notion of time per se. The absence of a concept of time is also attested in other Near eastern cultures, but stands in contrast to Graeco-Roman culture with its pervasive concept of chronos. The ancient Jewish view also stands in contrast with medieval Judaism, when the concept of time became well established in ethics, philosophy, biblical exegesis, and halakhah, a development which Stern attributes partly to the influence of Greek philosophy on medieval Jewish thinkers. He concludes with reflections on the wider implications of these findings, especially regarding the limited Hellenization of ancient Judaism and its cultural isolation within the Graeco-Roman world.This perceptive work, clearly, cogently, and convincingly argued, offers a new perspective on the world-view of ancient Judaism and its links with other cultures in the Near East of late antiquity.

Sects and sectarianism are popular themes in Jewish history, but the meaning of these terms is elusive, often raising more problems than solutions. This volume, drawing on the expertise of a wide range of scholars, examines several Jewish groups from Antiquity to the present day that have been traditionally identified as ‘sects’ or as ‘sectarian’, including most famously the Qumran community and the Qaraites. It questions whether ‘sect’ and ‘sectarianism’ are appropriate or effective as historical categories for the interpretation of social and religious movements in Jewish history.

The study of time, astronomy, and calendars, has been closely intertwined in the history of Western culture and, more particularly, Jewish tradition. Jewish interest in astronomy was fostered by the Jewish calendar, which was based on the courses of the sun and the moon, whilst astronomy, in turn, led to a better understanding of how time should be reckoned. Time, Astronomy, and Calendars in the Jewish Tradition, edited by Sacha Stern and Charles Burnett, presents a wide selection of original research in this multi-disciplinary field, ranging from Antiquity to the later Middle Ages. Its variety of approaches and sub-themes reflects the relevance of astronomy and calendars to many aspects of Jewish, and more generally ancient and medieval, culture and social history.Contributors include: Jonathan Ben-Dov, Reimund Leicht, Marina Rustow, Francois de Blois, Raymond Mercier, Philipp Nothaft, Josefina Rodriguez Arribas, Ilana Wartenberg, Israel Sandman, Justine Isserles, Anne C.

In the year 921/2, the Jewish leaders of Palestine and Babylonia disagreed on how to calculate the calendar. This led the Jews of the entire Near East to celebrate Passover and the other festivals, through two years, on different dates. The controversy was major, but it became forgotten until its late 19th-century rediscovery in the Cairo Genizah. Faulty editions of the texts, in the following decades, led to much misunderstanding about the nature, leadership, and aftermath of the controversy. In this book, Sacha Stern re-edits the texts completely, discovers many new Genizah sources, and challenges the historical consensus. This book sheds light on early medieval Rabbanite leadership and controversies, and on the processes that eventually led to the standardization of the medieval Jewish calendar.
