This book studies Abraham Ibn Ezra's (1089-1167) scientific thought. His life and oeuvre are viewed as the very embodiment of 'the rise of medieval Hebrew science', a process in which Jewish scholars gradually adopted the holy tongue as a vehicle to express scientific ideas.

The main focus of this book is the study of Abraham Ibn Ezra’s (1089-1167) scientific thought within the historical and cultural context of his times. His scientific contribution may be understood as the very embodiment of ‘the rise of medieval Hebrew science’, a process in which Jewish scholars gradually adopted the holy tongue as a vehicle to express secular and scientific ideas. The first part provides a comprehensive picture of Ibn Ezra’s scientific corpus. The second part studies his linguistic strategy. The third and fourth parts study Ibn Ezra’s introductions to his scientific treatises and the fifth part is devoted to studying four ‘encounters’ with Claudius Ptolemy, the main scientific character featuring in Ibn Ezra’s literary work.

From the Middle Ages until the present, the development of astrology among Jews was associated mainly with the name of Abraham Ibn Ezra (1089-1167). His scientific corpus deals with mathematics, astronomy, scientific instruments and tools, and the Jewish calendar; but especially with astrology. This volume is the first product of a larger enterprise-a scientific edition of all twelve Ibn Ezra's astrological treatises-and offers a critical Hebrew text of the two versions of Ibn Ezra's "Sefer ha-Te'amim," the Book of Reasons, accompanied by an annotated translation and commentary. The two treatises presented here were designed by Ibn Ezra to offer "reasons," "explanations," or "meanings" of the raw astrological concepts formulated in the introduction to astrology that Ibn Ezra entitled "Reshit Hokhmah" (Beginning of Wisdom).

Provides the first comprehensive overview by world-renowned experts of what we know today of medieval Jews' engagement with the sciences.

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. Kineret Sittig, Katharina Keim, and Sacha Stern

Christianity, Judaism and Islam - the Children of Abraham - constitute the spiritual foundations of Western civilization. They affect the interactions of entire nations and individuals, though their history is often understood as one of conflict and controversy. The present volume documents past encounters and confrontations, though it also shows that the history of the three faiths is not merely one of conflict but also one of co-existence and dialogue. The rich shared theological traditions of the Abrahamic religions provide positive encouragement to present-day meetings between their followers. The book contains 16 contributions by scholars from various fields of religious studies. It should appeal to everyone interested in interreligious encounters.

The twenty-eight essays in this collection showcase cutting-edge research in manuscript studies, encompassing material from late antiquity to the Renaissance. The volume celebrates the exceptional contribution of John Lowden to the study of medieval books.
