11. Islamic Astronomical Tables : Mathematical Analysis and Historical Investigation

Author

Benno van Dalen and Benno van Dalen

Subjects
QB23
Abstract

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 The four articles in the second part provide extensive studies of materials in unpublished primary sources on Islamic astronomy that heavily depend on these methods.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.

14. Islamic Astronomy in China: Two New Sources for the Huihui Li ('Islamic Calendar')

Author

Benno Van Dalen and Michio Yano

Abstract

In this talk we will discuss some aspects of the exchange of astronomical knowledge that took place between the Muslim world and China in the thirteenth and fourteenth century. In that period both the eastern part of the Muslim world, consisting of Persia and surrounding countries, and China, ruled by the Yuan Dynasty, were part of the Mongol world empire. In particular in the period between 1260 and 1280, astronomers as well as astronomical books and instruments were exchanged between Persia and China. As a result, extensive descriptions of a Chinese luni-solar calendar can be found in Arabic and Persian astronomical works from the Mongol period, whereas a Chinese text entitled Huihui Li (“Islamic Calendar”) can be seen to be a translation of a typical Islamic astronomical handbook with tables and explanatory text, in Arabic and Persian called zīj. Islamic astronomy had a good name in China because of its accurate prediction of eclipses, and the Huihui li was used parallel with the official Chinese calendar for almost 300 years.

Abstract

The authors analyse in more detail and more systematically than any earlier scholars the use of the terms jabr, muqābala, and some others in the solutions of a large number of algebraical problems in a range of medieval mathematical texts. They find that the terms stand for the immediate goals of particular steps in the resolutions, rather than for specific operations, as has been thought before. They thus also find that the phrase al-jabr wa’l-muqābala, which became to stand for the whole fi...

The author starts by giving a brief overview and description of instruments for tracing conic sections. He then analyses the origin of one such instrument, namely the conic compass, as it first appears in the work of Lorenzo della Volpaia (Florence, 1446-1512) and later with numerous other authors, including Leonardo da Vinci. He argues that earlier conclusions by modern scholars that the compass was a Renaissance invention are unconvincing. On the basis of a careful inspection of a large num...

Starting with the occurrence in De revolutionibus of the so-called Ṭūsī couple and Ibn al-Shāṭir’s (ca. AD 1350) planetary models involving multiple epicycles, recently also cosmological arguments have been considered. The 15th-century astronomer ‘Alī Qūsjī,...

The Sustaka Zīj by Ḥusayn ibn Mūsā al-Hurmūzī, which, judging from a number of sample calculations, was compiled in the early 11th century, is of a very different nature from the Arabic and Persian astronomical handbooks with tables that are usually called “zīj”. In fact, the Sustaka Zīj (possibly meaning “Sexagesimal Zīj” or “Pocket Zīj”) consists of only fourteen brief chapters, explaining for each of the seven planets, how to calculate its position from that of a certain period of time ago...

In this commentary, extant in nine manuscripts, he provides an alternative, equivalent definition of ratio by means of anthyphairesis, a process similar to the Euclidean algorithm for finding the greatest common divisor of two numbers.
