In Synchrony with the Heavens, Volume 2 Instruments of Mass Calculation


Book Description

This is the first investigation of one of the main interests of astronomy in Islamic civilization, namely, timekeeping by the sun and stars and the regulation of the astronomically-defined times of Muslim prayer. The study is based on over 500 medieval astronomical manuscripts first identified by the author, now preserved in libraries all over the world and originally from the entire Islamic world from the Maghrib to Central Asia and the Yemen. The materials presented provide new insights into the early development of the prayer ritual in Islam. They also call into question the popular notion that religion could not inspire serious scientific activity. Only one of the hundreds of astronomical tables discussed here was known in medieval Europe, which is one reason why the entire corpus has remained unknown until the present. A second volume, also to be published by Brill, deals with astronomical instruments for timekeeping and other computing devices.







Islamic Astronomy and Geography


Book Description

This volume of 12 studies, mainly published during the past 15 years, begins with an overview of the Islamic astronomy covering not only sophisticated mathematical astronomy and instrumentation but also simple folk astronomy, and the ways in which astronomy was used in the service of religion. It continues with discussions of the importance of Islamic instruments and scientific manuscript illustrations. Three studies deal with the regional schools that developed in Islamic astronomy, in this case, Egypt and the Maghrib. Another focuses on a curious astrological table for calculating the length of life of any individual. The notion of the world centred on the sacred Kaaba in Mecca inspired both astronomers and proponents of folk astronomy to propose methods for finding the qibla, or sacred direction towards the Kaaba; their activities are surveyed here. The interaction between the mathematical and folk traditions in astronomy is then illustrated by an 11th-century text on the qibla in Transoxania. The last three studies deal with an account of the geodetic measurements sponsored by the Caliph al-Ma'mûn in the 9th century; a world-map in the tradition of the 11th-century polymath al-Bîrûnî, alas corrupted by careless copying; and a table of geographical coordinates from 15th-century Egypt.




New Perspectives on the History of Islamic Science


Book Description

Recent studies in the history of Islamic science based on the discovery and study of new primary texts and instruments have substantially revised the views of nineteenth-century historians of science. This volume presents some of these ground-breaking studies as well as articles which shed new light on the ongoing academic debate surrounding the question of the decline of Islamic scientific tradition.




A Descriptive Catalogue of Indian Astronomical Instruments


Book Description

The large masonry instruments designed by Sawai Jai Singh and erected in his five observatories in the early eighteenth century mark the culmination of a long process of development in astronomical instrumentation. But what kind of astronomical instruments were used in India before Jai Singh's time? Sanskrit texts on astronomy describe the construction and use of several types of instruments. Are any of these extant in museums? Such questions led me to an exploration of nearly a hundred museums and private collections in India, Europe and USA for about a quarter century. The present catalogue is the outcome of this exploration. This catalogue describes each instrument in the context of the related extant specimens, while laying special emphasis on the interplay between Sanskrit and Islamic traditions of instrumentation. Therefore, each instrument type is organized in a separate section identified by the letters of the alphabet. These sections begin with introductory essays on the history of the instrument type and its varieties, followed by a full technical description of every specimen, with art historical notes. Moreover, all engraved data are reproduced and interpreted as far as possible. In some 4300 pages, it contains 600 entries, with introductory essays and long extracts from two important Sanskrit texts, namely Mahendra Sūri's Yantrarāja and Padmanābha's Dhruvabhramādhikāra, along with English translations. Following a suggestion that a shorter version of the Catalogue, consisting of all the introductory essays and appendices, but excluding the catalogue proper, would be easier for the general reader to handle, this Abridged Version has been prepared. The pagination here remains the same as in the Catalogue. Those who wish to read about individual instruments can always consult the Catalogue.




A Shared Legacy


Book Description

On the occasion of the 75th +1 anniversary of the publication of Prof. J. M. Millàs Vallicrosa’s seminal work Assaig d’història de les idees físiques i matemàtiques a la Catalunya medieval by the Institut d'Estudis Catalans, the Commission on the History of Science and Technology in Islamic Societies (International Union on History and Philosophy of Science), the Grup Millàs Vallicrosa d’Història de la Ciència Àrab (Universitat de Barcelona) and the Societat Catalana d’Història de la Ciència i de la Tècnica (Institut d’Estudis Catalans) organized a conference entitled “A Shared Legacy: Islamic Science East and West”. At this conference, the Islamic Scientific Manuscripts Initiative, a new joint project for the study of manuscripts, was presented. .Although the papers published in this volume deal with a mixture of subjects and disciplines - astronomical instruments, planetary models, geometry, medicine, miqat, technology and cartography - they all have the transmission of knowledge between the two shores of the Mediterranean as a common underlying thread...Amb motiu del 75è + 1 aniversari de la publicació del llibre Assaig d’història de les idees físiques i matemàtiques a la Catalunya medieval (IEC), la Commission on the History of Science and Technology in Islamic Societies (CHSTIS/IUPHS), el Grup Millàs Vallicrosa d’Història de la Ciència Àrab de la Universitat de Barcelona (UB) i la Societat Catalana d’Història de la Ciència i de la Tècnica (SCHCT) -filial de l’Institut d’Estudis Catalans- organitzaren el congrés A Shared Legacy. Islamic Science East and West (Un llegat compartit: ciència islàmica a orient i occident). .Am motiu d’aquesta trobada s’han recopilat els articles que conté aquest volum tracten de temes variats –instruments astronòmics, models planetaris, geometria, medicina, tecnologia, cartografia, etc.- que tenen com a nexe en comú la transmissió del coneixement entre les dues ribes de la Mediterrània.




Prognostication in the Medieval World


Book Description

Two opposing views of the future in the Middle Ages dominate recent historical scholarship. According to one opinion, medieval societies were expecting the near end of the world and therefore had no concept of the future. According to the other opinion, the expectation of the near end created a drive to change the world for the better and thus for innovation. Close inspection of the history of prognostication reveals the continuous attempts and multifold methods to recognize and interpret God’s will, the prodigies of nature, and the patterns of time. That proves, on the one hand, the constant human uncertainty facing the contingencies of the future. On the other hand, it demonstrates the firm believe during the Middle Ages in a future which could be shaped and even manipulated. The handbook provides the first overview of current historical research on medieval prognostication. It considers the entangled influences and transmissions between Christian, Jewish, Islamic, and non-monotheistic societies during the period from a wide range of perspectives. An international team of 63 renowned authors from about a dozen different academic disciplines contributed to this comprehensive overview.




Mathematics and the Divine


Book Description

Mathematics and the Divine seem to correspond to diametrically opposed tendencies of the human mind. Does the mathematician not seek what is precisely defined, and do the objects intended by the mystic and the theologian not lie beyond definition? Is mathematics not Man's search for a measure, and isn't the Divine that which is immeasurable ?The present book shows that the domains of mathematics and the Divine, which may seem so radically separated, have throughout history and across cultures, proved to be intimately related. Religious activities such as the building of temples, the telling of ritual stories or the drawing of enigmatic figures all display distinct mathematical features. Major philosophical systems dealing with the Absolute and theological speculations focussing on our knowledge of the Ultimate have been based on or inspired by mathematics. A series of chapters by an international team of experts highlighting key figures, schools and trains of thought is presented here. Chinese number mysticism, the views of Pythagoras and Plato and their followers, Nicholas of Cusa's theological geometry, Spinozism and intuitionism as a philosophy of mathematics are treated side by side among many other themes in an attempt at creating a global view on the relation of mathematics and Man's quest for the Absolute in the course of history.·Mathematics and man's quest for the Absolute·A selective history highlighting key figures, schools and trains of thought ·An international team of historians presenting specific new findings as well as general overviews·Confronting and uniting otherwise compartmentalized information

Islamic Thought in the Middle Ages


Book Description

The history of Islamic thought in the Middle Ages, the impact of Greek philosophy and science, and the formation of an own theological tradition, is a long and complex one. The articles in this volume dedicated to Hans Daiber, one of the pioneering scholars in this field, offer new insights from a variety of perspectives: philological, philosophical, and historical. The subjects range from Islamic philosophy and theology, over the history of science, the transmission into other medieval cultures to language and literature. In addition to their specific discoveries, they give an impression of the dynamics of medieval Islamic intellectual history as well as of the diversity of approaches needed to understand this dynamics.
