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...

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...

The present volume offers the first critical edition of the Hebrew text of the two versions of Ibn Ezra's Book of the World, accompanied by an English translation and a commentary. These twin treatises represent the first Hebrew work, unique in medieval Jewish science, to discuss the theories and techniques of historical and meteorological astrology that had accumulated from Antiquity to Ibn Ezra's time, on the basis of Greek, Hindu, Persian, and Arabic sources. This volume also incorporates the first critical edition, translated and annotated, of Māshāallāh's Book on Eclipses,...

This volume offers the first critical edition of the Hebrew text, with English translation and commentary, of seven astrological treatises by Abraham Ibn Ezra: the Book of Elections (3 versions); the Book of Interrogations (3 versions); and the Book of the Luminaries. This volume, then, covers the astrological doctrine of elections, which is concerned with finding the best time to begin a particular activity; the doctrine of interrogations, designed to allow astrologers to reply to questions related to daily life; and the astrological theory behind the doctrine of the...

The present volume offers the first critical edition, accompanied with English translation and commentary, of Sefer ha-Moladot, which addresses the doctrine of nativities and the system of continuous horoscopy in nativities, and of Sefer ha-Tequfah, which is devoted exclusively to continuous horoscopy in nativities. The doctrine of nativities makes predictions about the whole of an individual's subsequent life on the basis of the natal chart, and the system of continuous horoscopy in nativities is concerned with the interval between life and death and makes predictions based...

The present volume offers a critical edition of the Hebrew texts, accompanied by English translation and commentary of Reshit Ḥokhmah (Beginning of Wisdom) and Mishpeṭei ha-Mazzalot (Judgments of the Zodiacal Signs) by Abraham Ibn Ezra (ca. 1089-ca. 1161). The first, the summa and by far the longest of his astrological works, the target of the most cross-references from the rest of that corpus and the most influential, enjoyed the widest circulation among Jews in the Middle Ages and after. The second, by contrast, is the most obscure. It is never referred to...

The present volume focuses on Henry Bate of Mechelen (1246–after 1310), the first scholar to bring Ibn Ezra’s astrological work to the knowledge of Latin readers. The volume has two main objectives. The first is to offer as complete and panoramic an account as possible of Bate’s translational project. Therefore, this volume offers critical editions of all six of Bate’s complete translations of Ibn Ezra’s astrological writings. The second objective is to accompany Bate’s Latin translations with literal English translations and to offer a thorough collation of the Latin translation...
