Its study and use as a propaedeutic for more advanced teaching texts is evidenced by thousands of extant copies of the original and its numerous commentaries, super commentaries, and glosses. This dissertation, first and foremost, provides a critical edition and English translation of, and commentary on, this important and influential treatise. Due to ambiguity within the literature regarding exactly when Jaghmīnī flourished (which even led to speculation that there could have been two Jaghmīnīs), the focus of Chapter One is devoted to establishing Jaghmīnī’s dates and arguing that he was the sole author of both the Mulakhkhaṣ and the equally popular medical treatise al-Qānūnča. Among other things, this highlights that one scholar was composing multiple scientific textbooks in the late-twelfth/early-thirteenth century under the auspices of the Khwārizm Shāhs in Central Asia, a period often considered one of scientific stagnation. Chapter Two situates the Mulakhkhaṣ within the broader context of the genre of astronomical literature termed ʿilm al-hayʾa, a corpus of works that attempted to explain the physical structure of the universe as a whole, and a tradition of which the Mulakhkhaṣ was very much a part. Included in this chapter is a survey of summary accounts of theoretical astronomy of Jaghmīnī’s predecessors, both Ancient and Islamic, as potential sources for the Mulakhkhaṣ. Chapter Three makes the case that the target audience of Jaghmīnī’s Mulakhkhaṣ was, in the first instance, students studying in madrasas, where his work would have been seen as providing a cosmology glorifying God’s creation. The more general issue raised here is whether the standard approach to the pedagogy of Islamic science tends to promote its history as discrete episodes and dependent in the main on courtly patronage or individual initiatives, i.e., outside the core institutional structures of Islamic societies. It is then argued that a serious consequence of this has been the neglect of the vital role religious institutions played in sustaining scientific education in premodern Islam. iv RÉSUMÉ Le Mulakhkhaṣ fī al-hayʾa al-basīṭa, composé par Maḥmūd ibn Muḥammad ibn ʿUmar al-Jaghmīnī au début du XIIIe siècle, était un manuel astronomique extrêmement populaire qui devait jouer un rôle essentiel dans l’enseignement, la diffusion et l’institutionnalisation de l’astronomie théorique islamique. Son étude et son utilisation comme propédeutique pour les textes d’enseignement plus avancés est attestée par des milliers de copies existantes de l’original, ses nombreux commentaires, les commentaires sur les commentaires et des gloses. Cette thèse, d’abord et avant tout, offre une édition critique, une traduction en anglais et un commentaire de ce traité important et influent. En raison de l’ambiguïté existant dans la littérature quant à la période exacte à laquelle Jaghmīnī était en activité (qui a même conduit à la spéculation qu’il pourrait y avoir eu deux Jaghmīnīs), la mise au point du premier chapitre est consacrée à établir les dates de Jaghmīnī et le fait qu’il était le seul auteur à la fois du Mulakhkhaṣ et d’un tout aussi populaire traité médical intitulé al-Qānūnča.

  • The History of Arabic Sciences: a Selected Bibliography
    THE HISTORY OF ARABIC SCIENCES: A SELECTED BIBLIOGRAPHY Mohamed ABATTOUY Fez University Max Planck Institut für Wissenschaftsgeschichte, Berlin A first version of this bibliography was presented to the Group Frühe Neuzeit (Max Planck Institute for History of Science, Berlin) in April 1996. I revised and expanded it during a stay of research in MPIWG during the summer 1996 and in Fez (november 1996). During the Workshop Experience and Knowledge Structures in Arabic and Latin Sciences, held in the Max Planck Institute for the History of Science in Berlin on December 16-17, 1996, a limited number of copies of the present Bibliography was already distributed. Finally, I express my gratitude to Paul Weinig (Berlin) for valuable advice and for proofreading. PREFACE The principal sources for the history of Arabic and Islamic sciences are of course original works written mainly in Arabic between the VIIIth and the XVIth centuries, for the most part. A great part of this scientific material is still in original manuscripts, but many texts had been edited since the XIXth century, and in many cases translated to European languages. In the case of sciences as astronomy and mechanics, instruments and mechanical devices still extant and preserved in museums throughout the world bring important informations. A total of several thousands of mathematical, astronomical, physical, alchemical, biologico-medical manuscripts survived. They are written mainly in Arabic, but some are in Persian and Turkish. The main libraries in which they are preserved are those in the Arabic World: Cairo, Damascus, Tunis, Algiers, Rabat ... as well as in private collections. Beside this material in the Arabic countries, the Deutsche Staatsbibliothek in Berlin, the Biblioteca del Escorial near Madrid, the British Museum and the Bodleian Library in England, the Bibliothèque Nationale in Paris, the Süleymaniye and Topkapi Libraries in Istanbul, the National Libraries in Iran, India, Pakistan..

  • The Language of «Patronage» in Islamic Societies Before 1700
    THE LANGUAGE OF «PATRONAGE» IN ISLAMIC SOCIETIES BEFORE 1700 Sonja Brentjes Max Planck Institut für wissenschaftsgeschichte Resumen No resulta fácil escribir sobre el lenguaje del mecenazgo en las sociedades islámicas, dado que en el árabe y el persa medievales no existe un término preciso para describirlo. A través de los siglos y en contextos diferentes se utilizan diversos términos para designar tal realidad. En ocasiones unas simples palabras bastaban para expresar relaciones de jerarquía, ascenso social o conocimiento entre las personas, mientras que otras veces se requería de un auténtico caudal lingüístico por el que se narraban, calibraban y enjuiciaban dichas relaciones. El uso de dichas palabras, así como su signifi cado, estaba también defi nido espacial y socialmente. Este estudio pretende ofrecer una descripción de los problemas básicos a los que nos en- frentamos, ilustrándolos mediantes ejemplos procedentes de la medicina, la astrología y en ocasiones de la fi losofía y la teología. Palabras clave: mecenazgo, sociedades islámicas, vocabulario. Abstract It is by no means easy to write a meaningful paper about the language of «patronage» in 11 Islamic societies, because in medieval Arabic and Persian there is no unambiguous term for it. Over the centuries and in diff erent contexts, there were various terms to describe this reality. Sometimes only a few words suffi ced to express relationships of hierarchy, promo- tion and knowledge between people, while at other times a veritable linguistic manifold was tapped into for narrating, diff erentiating and evaluating. Th e use of the words and their meaning diff ered also territorially and socially.

  • A Lesson from the Arcane World of the Heavenly Spheres According to Maimonides
    A LESSON FROM THE ARCANE WORLD OF THE HEAVENLY SPHERES ACCORDING TO MAIMONIDES by DAVID R. BLUMENTHAL Emory Univeristy, Atlanta, GA 30322 The Teaching and the Text So that the ordinary Jew have an informed view of creation as a step toward true conviction about God, Maimonides devotes chapter three of "Hillscot yesode hattoriih" of the Mifoe Torah to an exposition of medieval astrophysics. The system he expounds has several traits that are strange to modern ears: first, it is geocentric; second, the heavenly bodies do not move by themselves in space but are embedded in transparent spheres which move; third, there is no empty space at all between these spheres; and fourth, Aristotelian physics demanded a system with circular uniform movement about a single fixed center. However, since the actually observed motions of the heavenly bodies do not fit this model, ancient and medieval astrophysicists invented a complicated series of spheres-within-spheres to account for the actual phenomena. This attempt to "save the phenomena," as Simplicius put it, seems very artificial to us, particularly since we now know it to have been a useless undertaking. We reject geocentrism, we accept the idea of space, and we are not bound by the idealist definitions of motion in Aristotelian physics. Maimonides, however, accepted all this and, as we shall see, took an important place in the extended fight over which of the explanations available to him was the correct one. 1 I. The best history of these matters remains the classic by Duhem ( 1913). Volumes I and II cover antiquity and the middle ages.

  • We Are Publishing the Correct Times of the Presidency of Religious Affairs (Of Türkiye) in the Year 1982 and Before
    As the “Türkiye Calendar”, we are publishing the correct Times of the Presidency of Religious Affairs (of Türkiye) in the year 1982 and before. The Presidency of Religious Affairs (of Türkiye) changed those correct times beginning on 1 January 1983. All imsâk and salât times published by the Presidency of Religious Affairs (of Türkiye) since 1983 up to the present day are all wrong. Before the year 1983, the salât times in all calendars were all the same. As a matter of fact, the correct time calculation principles and rules have been abandoned in all Calendars published by the Presidency of Religious Affairs, beginning first with the year 1983; while in all calendars the true times of imsâk and salât were given, as can be seen in any calendar one looks at published in Türkiye in 1982 and the preceding years. It is proved below that the times of imsâk and salâts published by the Presidency of Religious Affairs are erroneous even according to the evidences belonging to the Presidency of Religious Affairs themselves. EXPLANATION ON THE ERRONEOUS SALÂT TIMES IN 1983 AND THE FOLLOWING YEARS As can be seen on the calendar pages given above, the salât times have been changed by the Presidency of Religious Affairs (of Türkiye) beginning with 1 January 1983. While no change had taken place in the celestial 1 (orderly) motions of the Globe and the Sun, the imsâk times have been changed for Ankara; by taking 20 minutes forward (later) the imsâk time, and by taking backward (earlier) 9 minutes the ‘ishâ’ (nightfall).

  • Two Early Arabic Sources on the Magnetic Compass
    TWO EARLY ARABIC SOURCES ON THE MAGNETIC COMPASS Petra G. Schmidl FRANKFURT In this paper two previously unpublished texts on the magnetic compass from the medieval Islamic world will be discussed, the first by the Yemeni Sultan al- Ashraf (ca. 1290) and the second by the Cairene astronomer Ibn Simô¢un (ca. 1300). These two treatises constitute the earliest known evidence attesting the use of the magnetic compass for the determination of the qibla, the sacred direction of Islam. A brief introduction glimpses at the history of the magnetic compass in Europe and China and mentions previously known early Arabic sources on the instrument and its use. This is followed by some remarks on the authors and the manuscripts, the Arabic texts with English translations, and comments on problems encountered while working on the texts. 1. Survey of the history of the magnetic compass The Yemeni astronomer-prince al-Ashraf (ca. 1290) and (apparently) also a Cairene astronomer called Ibn Simô¢un (ca. 1300)1 both wrote treatises on the magnetic compass. These two previously unpublished texts will be presented in this paper, prefaced by a brief survey of the knowledge on and use of the magnetic compass in the European and Islamic Middle Ages in order to put these new sources in the context of previous knowledge on the subject. Although the magnet and its attractive property were known in Antiquity, there is no mention of its directive potential in the sources.2 In the late nine- 1 Prof. David A. King informs me that the author is probably an Egyptian as- tronomer and muezzin called Ibn Simô¢un; see further King, article “®T¢asa” in EI2; Suter, “Mathematiker und Astronomen,” 1900, p.
