This book provides a critical edition of the mathematical tables in the popular Arabic astronomical handbook of the Iranian astronomer Kūshyār ibn Labbān (c. 1000). The Jāmiʿ Zīj (Comprehensive Zīj) was a highly popular Arabic astronomical handbook with tables written by the Iranian astronomer Kūshyār ibn Labbān al-Jīlī around the year 1000. It belonged to an important category of works, modelled after Ptolemy’s Almagest and Handy Tables, that allowed the practising astronomer/astrologer to carry out all necessary calculations of arcs on the celestial sphere and planetary positions, and ultimately to cast horoscopes. Around one hundred such works are extant, but only very few have been edited, translated or studied in detail. This book contains a full treatment of Book II of Kūshyār’s astronomical handbook centred around a critical edition of all the mathematical tables and their paratexts. It sets new standards for the edition of such tables by designing new types of apparatus entries for related variants in the tabular values. The introductory part describes the eight surviving manuscripts that transmit Kūshyār’s tables and establishes by a detailed survey that they represent at least three different versions of the Jāmiʿ Zīj that in all likelihood stem from Kūshyār himself. An extensive commentary with mathematical analyses uncovers numerous new details of the methods by which the tables were computed, the astronomical parameter values on which they were based, the sources for the tables, and their influence on later zījes. These results show how Kūshyār, on the one hand, stayed firmly within the framework of the Ptolemaic tradition, but on the other introduced several types of innovations that later became common in Arabic and Persian astronomical handbooks.

Astronomical tables are a significant yet understudied part of the scientific historical corpus. They circulated among many cultures, and were adopted and transformed by astronomical practitioners for a variety of purposes. The numerical data conveyed in these tables provides rich evidence for pre-modern scientific practices. In the last fifty years, new approaches to the analysis and critical editing of astronomical tables have flourished due to advances in computing power and associated modern mathematical tools. In more recent times, the rapid growth of digital humanities and modern data analysis promises exciting further developments in this area. The present collection of studies on astronomical tables captures this momentum. It is a result of long-term collaborative work on building a database of astronomical tables and other objects found in manuscripts, released under the name DISHAS (Digital Information System for the History of Astral Sciences). The fourteen contributions in this volume provide a broad coverage of astronomical traditions throughout Eurasia and North Africa, which, with very few exceptions, find their roots in the mathematical astronomy of Ptolemy. The contributions include critical editions of previously unexamined astronomical tables along with insightful mathematical analyses, as well as reflective methodological surveys that open up new perspectives for research on these fundamental sources for the history of mathematics and astronomy.

Claudius Ptolemy (c. 100-170 AD) is one of the most influential scholars of all time. While he is also the author of treatises on geography, optics and harmonics, his fame primarily stems from two works on the science of the stars, dealing with mathematical astronomy (the 'Almagest') and astrology (the 'Tetrabiblos'). The 'Almagest' and the 'Tetrabiblos' remained the fundamental texts on the science of the stars for some 1500 years. Both were translated several times into Arabic and Latin and were heavily commented upon, glossed, discussed, and also criticised and improved upon, in the Islamic world and in Christian Europe. Yet, the reception of Ptolemy in medieval cultures is still to a large extent a terra incognita of the history of science. The Arabic and Latin versions of the 'Almagest' and the 'Tetrabiblos' are for the most part unavailable in modern editions, their manuscripts remain largely unexplored and, generally speaking, their history until the seventeenth century has never been systematically investigated.00This volume gathers together 16 contributions dealing with various aspects of the reception of Ptolemy?s astronomy and astrology in the Islamic world and in Christian Europe up to the seventeenth century. Contributions are by José Bellver, Jean-Patrice Boudet, Josep Casulleras, Bojidar Dimitrov, Dirk Grupe, Paul Hullmeine, Alexander Jones, Richard L. Kremer, Y. Tzvi Langermann, Ma José Parra, H. Darrel Rutkin, Michael H. Shank, Nathan Sidoli, Carlos Steel, Johannes Thomann and Henry Zepeda.
