A Survey of Islamic Astronomical Tables


Book Description

The source material for the study of medieval oriental astronomy consists of Byzantine Greek, Sanscrit, Hebrew, Arabic, Persian, and Turkish astronomical and astrological manuscripts. If one desires to build up a detailed picture of Islamic astronomy, one can choose material from these available manuscripts. Of these manuscripts it is possible to isolate a group of works, the "zijes". A "zij" consists of the numerical tables and accompanying explanation sufficient to measure time and to compute planetary and stellar positions, appearance, and eclipses. This paper is a survey of the number, distribution, contents, and relations between "zijes" written in Arabic or Persian during the period from the 8th through the 15th centuries. Illustrations. Oversize.




Islamic Astronomical Tables


Book Description

This volume comprises nine articles on Islamic astronomy published since 1989 by Benno van Dalen. Van Dalen was the first historian of Islamic astronomy who made full use of the new possibilities of computers in the early 1990s. He implemented various statistical and numerical methods that can be used to determine the mathematical properties of medieval astronomical tables, and utilized these to obtain entirely new, until then unattainable historical results concerning the interdependence of individual tables and hence of entire astronomical works. His programmes for analysing tables, making sexagesimal calculations and converting calendar dates continue to be widely used. The five articles in the first part of this collection explain the principles of a range of statistical methods for determining unknown parameter values underlying astronomical tables and present extensive step-by-step examples for their use. The four articles in the second part provide extensive studies of materials in unpublished primary sources on Islamic astronomy that heavily depend on these methods. The volume is completed with a detailed index.




Sanskrit Astronomical Tables


Book Description

This groundbreaking volume provides an up-to-date, accessible guide to Sanskrit astronomical tables and their analysis. It begins with an overview of Indian mathematical astronomy and its literature, including table texts, in the context of history of pre-modern astronomy. It then discusses the primary mathematical astronomy content of table texts and the attempted taxonomy of this genre before diving into the broad outlines of their representation in the Sanskrit scientific manuscript corpus. Finally, the authors survey the major categories of individual tables compiled in these texts, complete with brief analyses of some of the methods for constructing and using them, and then chronicle the evolution of the table-text genre and the impacts of its changing role on the discipline of Sanskrit jyotiṣa. There are also three appendices: one inventories all the identified individual works in the genre currently known to the authors; one provides reference information about the details of all the notational, calendric, astronomical, and other classification systems invoked in the study; and one serves as a glossary of the relevant Sanskrit terms.







An Eleventh-Century Egyptian Guide to the Universe


Book Description

Acquired by the Bodleian Library in 2002, the Book of Curiosities is now recognized as one of the most important discoveries in the history of cartography in recent decades. This eleventh-century Arabic treatise, composed in Egypt under the Fatimid caliphs, is a detailed account of the heavens and the Earth, illustrated by an unparalleled series of maps and astronomical diagrams. With topics ranging from comets to the island of Sicily, from lunar mansions to the sources of the Nile, it represents the extent of geographical, astronomical and astrological knowledge of the time. This authoritative edition and translation, accompanied by a colour facsimile reproduction, opens a unique window onto the worldview of medieval Islam. An extensive glossary of star-names and seven indices, on birds, animals and other items have been added for easy reference.







A History of Arabic Astronomy


Book Description

A History of Arabic Astronomy is a comprehensive survey of Arabic planetary theories from the eleventh century to the fifteenth century based on recent manuscript discoveries. George Saliba argues that the medieval period, often called a period of decline in Islamic intellectual history, was scientifically speaking, a very productive period in which astronomical theories of the highest order were produced. Based on the most recent manuscript discoveries, this book broadly surveys developments in Arabic planetary theories from the eleventh century to the fifteenth. Taken together, the primary texts and essays assembled in this book reverse traditional beliefs about the rise and fall of Arabic science, demonstrating how the traditional “age of decline” in Arabic science was indeed a “Golden Age” as far as astronomy was concerned. Some of the techniques and mathematical theorems developed during this period were identical to those which were employed by Copernicus in developing his own non-Ptolemaic astronomy. Significantly, this volume will shed much-needed light on the conditions under which such theories were developed in medieval Islam. It clearly demonstrates the distinction that was drawn between astronomical activities and astrological ones, and reveals, contrary to common perceptions about medieval Islam, the accommodation that was obviously reached between religion and astronomy, and the degree to which astronomical planetary theories were supported, and at times even financed, by the religious community itself. This in stark contrast to the systematic attacks leveled by the same religious community against astrology. To students of European intellectual history, the book reveals the technical relationship between the astronomy of the Arabs and that of Copernicus. Saliba’s definitive work will be of particular interest to historians of Arabic science as well as to historians of medieval and Renaissance European science.




A Survey of the Almagest


Book Description

The Almagest, by the Greek astronomer and mathematician Ptolemy, is the most important surviving treatise on early mathematical astronomy, offering historians valuable insight into the astronomy and mathematics of the ancient world. Pedersen's 1974 publication, A Survey of the Almagest, is the most recent in a long tradition of companions to the Almagest. Part paraphrase and part commentary, Pedersen's work has earned the universal praise of historians and serves as the definitive introductory text for students interested in studying the Almagest. In this revised edition, Alexander Jones, a distinguished authority on the history of early astronomy, provides supplementary information and commentary to the original text to account for scholarship that has appeared since 1974. This revision also incorporates various corrections to Pedersen's original text that have been identified since its publication. This volume is intended to provide students of the history of astronomy with a self-contained introduction to the Almagest, helping them to understand and appreciate Ptolemy's great and classical work.

Astronomy and Astrology in al-Andalus and the Maghrib


Book Description

This new volume of papers by Julio Samsó deals with the development of astronomy and astrology in al-Andalus and the Maghrib between the 10th and the 19th centuries. Opening with a survey of the social history of the exact sciences in al-Andalus, the book then looks at astronomical tables: the first stages of the introduction of al-Khwarizmi's and al-Battani's tables through the school of Maslama al-Majriti, the development of Ibn al-Zarqalluh/ Azarquiel's theories in Maghribi zijes (Ibn al-Banna' and Ibn Azzuz) and the abandonment of this tradition towards the end of the 14th century. From this period onwards new Eastern zijes (Muhyi al-Din al-Maghribi, Ibn al-Shatir, Ulugh Beg) are introduced in the Maghrib and, towards the beginning of the 17th century, a translation of Abraham Zacut and José Vizinho's Almanach Perpetuum (end of the 15th century) becomes well known in the whole Islamic world, from Morocco to the Yemen. As well as zijes themselves, the author also deals with theoretical astronomy (the use of an elliptical deferent for Mercury in Ibn al-Zarqalluh's equatorium and the criticisms of Ibn al-Haytham and Jabir b. Aflah on Ptolemy's determination of the parameters of the same planet), and with the use of zijes for the calculation of horoscopes, and an experimental astrological method for the correction of mean motion planetary tables (Ibn Azzuz).
