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 mainly on anniversary horoscopes, which are juxtaposed with the natal horoscope. To Abraham Ibn Ezra's mind, not only are these two doctrines the core of astrology; they also epitomize the praxis of the astrological metier."

Abraham Ibn Ezra was “reborn” in the Latin West in the last decades of the thirteenth century thanks to a plethora of authored and anonymous Latin translations of his astrological writings. The present volume offers the first critical edition, accompanied by an English translation, a commentary, and an introductory study, of Liber nativitatum (Book of Nativities) and Liber Abraham Iudei de nativitatibus (Book on Nativities by Abraham the Jew), two astrological treatises in Latin that were written by Abraham Ibn Ezra or attributed to him, and whose Hebrew source-text or archetype has not survived. The first is undoubtedly an anonymous Latin translation of the second version of Ibn Ezra’s Sefer ha-moladot (Book of Nativities), whose Hebrew source text is otherwise lost. The second is the most mysterious specimen among the Latin works attributed to Ibn Ezra that have no extant Hebrew counterpart. The present volume shows not only that the Liber Abraham Iudei de nativitatibus underwent a significant metamorphosis over time and was transmitted in four significantly different versions, but also that its date of composition is not that previously accepted by modern scholarship. "These volumes represent a major achievement in the history of medieval astrology and it is no wonder that they have already become classics, often referred to by specialists in the field, including by this reviewer." -David Juste, Ptolemaeus Arabus et Latinus, Munich, Journal for the History of Astronomy 51 (I) (2020)

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 elsewhere by its author and is the only work for which Ibn Ezra’s authorship must be substantiated. Reshit Ḥokhmah and Mishpeṭei ha-Mazzalot were written in order to explain concepts common to the various branches of astrology that Ibn Ezra addressed elsewhere and to elucidate the worldview that underlies astrology. These two treatises are the richest and most varied with regard to the astrological information they present. Reshit Ḥokhmah and Mishpeṭei ha-Mazzalot also exemplify the close collaboration between astronomy and astrology in medieval science and are the two components of Ibn Ezra’s astrological corpus with the most extensive, comprehensive, and significant astronomical content. "A critical edition with English translation of Reshit Ḥokhmah was published in 1998 by Epstein. Sela has not only aspired to improve it but also supplied a commentary to render the text more comprehensible. Sela’s mission is successfully accomplished for both treatises. This multifarious book is another important contribution to a deeper understanding of the life and work of one of the most important medieval Jewish polymaths." - Ilana Wartenberg, Universität Bern, in: Journal for the History of Astronomy 50.1 (2019)

The present volume offers the first critical edition, accompanied by an English translation, a commentary, and an introductory study, of the Liber electionum, the Liber interrogationum, and the Tractatus particulares, written by or attributed to Abraham Ibn Ezra.

The present volume focuses on Henry Bate, the first scholar to bring Ibn Ezra’s astrological work to the knowledge of Latin readers, and offers critical editions of all six of Henry Bate’s complete translations of Ibn Ezra’s astrological writings.

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.

This volume makes available two hitherto unpublished Latin texts on astronomical tables, written by Abraham Ibn Ezra and Robert of Chester, which together shed new light on the mid-twelfth-century assimilation of Graeco-Arabic mathematical astronomy in Christian Europe.

Critical edition of the earliest known astrological autobiography The present book reveals the riches of the earliest known astrological autobiography, authored by Henry Bate of Mechelen (1246–after 1310). Exploiting all resources of contemporary astrological science, Bate conducts in his Nativitas a profound self-analysis, revealing the peculiarities of his character and personality at a crucial moment of his life (1280). The result is an extraordinarily detailed and penetrating attempt to decode the fate of one’s own life and its idiosyncrasies. The Astrological Autobiography of a Medieval Philosopher offers the first critical edition of Bate’s Nativitas. An extensive introduction presents Bate’s life and work and sheds new light on the reception and use of Greek, Latin, Arabic, and Hebrew texts among scholars in Paris at the end of the 13th century. The book thus provides a major new resource for scholars working on medieval science, autobiography, and notions of personhood and individuality.

This volume offers the first critical edition, 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.
