The Exalted Fath: Ha-Emunah ha-Ramah Transleted by Solomon Ibn Lavi, Ha-Emunah ha-Nissaʼah Transleted by Samuel Ibn Matut, The Anonymous Commentary to HaEmunah ha-Ramah.

Abraham ibn Ezra d'Espagne (m. 1167) fut l'un des plus importants savants ayant contribué à la transmission de la science arabe à l'Occident. Ses ouvrages en astrologie et en astronomie, rédigés en hébreu puis traduits en latin, étaient considéréd comme faisant autorité par de nombreux savants juifs et Chrétiens. Parmi les ouvrages qu'il a traduits de l'arabe en hébreu, certains sont perdus dans leur langue originale et ses propres ouvrages renferment certaines informations concernant des sources anciennes mal ou pas (...) du tout connues par ailleurs. Ibn Ezra semble être le premier a avoir consigne l'une des sept méthodes pour dresser les maisons astrologiques. Cette méthode avait par la suite été utilisée par Lévi ben Gershom (m. 1344) dans le Midi de la France. (shrink)

The biblical story on the miracle of the manna in the Sinai Desert aroused many discussions and interpretations over the generations. The current study focuses on Ibn Ezra’s controversy with Hiwi al-Balkhi on the question of whether the manna was a natural or miraculous phenomenon. The article explores the claims of the two sides in light of the historical evidence and the literature describing the phenomenon of ‘falling manna’ in various areas of the Sinai Desert and Eastern countries. According to (...) Hiwi, the manna that rained down on the Israelites is taranjebin, a semi-liquid resinous sweet secretion of insects (honeydew) that exudes onto plants. Ibn Ezra deals with Hiwi’s claims through a series of refutations and arguments. He argues that the characteristics of the taranjebin do not fit the description of the biblical manna. For example, it does not come down in the Sinai Desert, it appears during a limited season, does not melt in the sun and does not rot during the night, and serves as a medicine rather than as food. Contribution: This article contributes to the understanding of Hiwi al-Balkhi’s identification of the biblical manna as honeydew and Ibn Ezra’s claims against his thesis. It expounds the commentators’ interpretations from a multidisciplinary perspective, such as the reality of harvesting the taranjebin in Iran and North Africa and its uses as food and medicine in the medieval culture.

Abraham ibn Ezra, the subject of this Cologne doctoral dissertation, is a lesser-known figure in the history of Jewish philosophy in medieval Spain, his dates placing him roughly after Ibn Gabirol and before Moses Maimonides. The title given to this book calls first for some comment. By "Religionsphilosophie," a term he has seemingly inherited from his scholarly predecessors, Greive does not mean "philosophy of religion," but is referring to a system of reality and of knowledge concerned with a metaphysical (...) ultimate principle and our relation to that principle, and in which no divide is established between "religion" and "philosophy," between "mysticism" and "rational thought"., accommodating his faith to his philosophy.) This system, as it is found in Ibn Ezra, conforms in its general lines to the Neoplatonic-inspired philosophy common in medieval Islamic and Jewish thought. A second comment might be made concerning the scope of Greive’s work. It is not his intent to present a full and systematic account of Ibn Ezra’s philosophy. He wishes rather to provide a careful reconstruction of certain aspects of Ibn Ezra’s thought which will represent an improvement on earlier scholarly accounts and will serve to illuminate Ibn Ezra’s philosophy as a whole. Following a brief review of Ibn Ezra’s Jewish philosophical predecessors, Greive surveys previous scholarly work on Ibn Ezra, finding confusion and misinterpretation of particular theories and a tendency to relate Ibn Ezra to Ibn Gabirol while ignoring Islamic influences. Greive then proceeds to his corrective treatment of aspects of Ibn Ezra’s thought, but not before surveying Ibn Ezra’s life, works and posthumous influence, noting that an account of Ibn Ezra’s philosophical thought must draw from all his literary production, as he did not compose a strictly philosophical work. There is one possible exception, Ibn Ezra’s prose poem Haj ben Meqis, which Greive presents in the latter part of his book in German translation with introduction and notes, and which, for Greive, can serve to demonstrate Ibn Ezra’s dependence vis-à-vis Avicenna. The book ends with a translation of a short poem, the Arugat ha-hokmah, and a very useful bibliography and indices. (shrink)

Abraham ibn Ezra's scientific corpus represented an exceptional case: instead of the common Latin model embodied by the scholar coming from the Christian North to the Iberian Peninsula to initiate a translation enterprise, we have in Ibn Ezra the contrary case of an intellectual imbued with the Arabic culture, who abandons al-Andalus, roams around the Christian countries and delivers in his wandering through Italy, France and England, the scientific and cultural cargo that he amassed during his youth in al-Andalus. (...) The main purpose of this article is to provide a picture of Ibn Ezra's scientific corpus as comprehensive and detailed as possible given the present state of research. The paper will fall into two main parts: Ibn Ezra's scientific work will be broken up into three main genres: Mathematics, Astronomy, Scientific Instruments and Tools; The astrological encyclopaedia; Translations from Arabic into Hebrew. In the second part, Ibn Ezra's scientific corpus will be reassembled as a whole in order to provide a global characterization, trying to point out its general organization and shape, and to indicate its main aims and special traits revealing Ibn Ezra personal contribution.

Abraham Ibn Ezra’s (ca. 1089-ca. 1161) astrological corpus includes the two versions of Sefer ha-ʿOlam (Book of the World), which represent the first Hebrew theoretical 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. This article surveys the content of the two versions of Sefer ha-ʿOlam and their most important doctrines as he conceived of them. The relevant material is presented chronologically: (a) (...) the ancient period; (b) the Hellenistic period; (c) Indian and Persian contributions; (d) contributions by astrologers working in the Muslim world; and (e) connections with twelfth-century Latin work on world astrology. In addition, this paper examines the contents of three additional texts by Ibn Ezra, directly concerned with word astrology: (a) the tenth chapter of Reshit Ḥokhmah (Beginning of Wisdom), where Ibn Ezra presents a series of cycles related to world astrology; (b) the astrological section of the exegetical excursus in the long commentary on Exodus 33:21, where Ibn Ezra inserts material on world astrology into his biblical commentary; (c) the introduction to Sefer ha-Moladot (Book of Nativities), where Ibn Ezra juxtaposes world astrology and the doctrine of nativities and presents a series of original ideas about world astrology.

Le Tractatus particulares est un ouvrage en quatre parties attribué à Abraham Ibn Ezra (ca. 1089-ca. 1161), qui nous est parvenu en deux traductions latines. Le présent article montre que, malgré les attestations dans les incipits et les explicits des deux traductions latines, le Tractatus particulares ne peut pas être un ouvrage authentique d’Ibn Ezra, ni un recueil d’écrits de sa plume. L’essentiel du Tractatus particulares est constitué de traductions de l’arabe en hébreu, réalisées bien après la mort d’Ibn (...) Ezra et associées à son nom par la suite. L’article entend aussi montrer que la source hébraïque du Tractatus particulares était sans doute conçue comme un ouvrage astrologique complet, une sorte d’encyclopédie astrologique médiévale.
