Thabit Ibn Qurra

Thabit ibn Qurra (826–901) was one of history’s most original thinkers and displayed expertise in the most difficult disciplines of this time: geometry, number theory, and astronomy as well as ontology, physics, and metaphysics. Approximately a dozen of this shorter mathematical and philosophical writings are collected in this volume. Critically edited with accompanying commentary, these writings show how Thabit Ibn Qurra developed and reconceived the intellectual inheritance of ancient Greece in all areas of knowledge.

An understanding of developments in Arabic mathematics between the IXth and XVth century is vital to a full appreciation of the history of classical mathematics. This book draws together more than ten studies to highlight one of the major developments in Arabic mathematical thinking, provoked by the double fecondation between arithmetic and the algebra of al-Khwarizmi, which led to the foundation of diverse chapters of mathematics: polynomial algebra, combinatorial analysis, algebraic geometry, algebraic theory of numbers, diophantine analysis and numerical calculus. Thanks to epistemological analysis, and the discovery of hitherto unknown material, the author has brought these chapters into the light, proposes another periodization for classical mathematics, and questions current ideology in writing its history. Since the publication of the French version of these studies and of this book, its main results have been admitted by historians of Arabic mathematics, and integrated into their recent publications. This book is already a vital reference for anyone seeking to understand history of Arabic mathematics, and its contribution to Latin as well as to later mathematics. The English translation will be of particular value to historians and philosophers of mathematics and of science.

De Imaginibus, "On Images" is, after Picatrix, the most important text for medieval and Renaissance astrological magic. De Imaginibus represents the height of astrological magic technique and goes far beyond merely planetary talismans in using the full range of traditional astrological technique developed by the sophisticated Harranian Sabians. De Imaginibus explains how to create house based talismans, how to use horary questions to forecast and anchor talismans and how to tune talismans to individual natal charts. The translator, John Michael Greer, is a noted Latinist and esoteric author. He is the co-translator of the Complete Picatrix. This translation was made from Francis Carmody's Latin critical edition of the astronomical works of Thabit Ibn Qurra and contains two variant texts along with extensive commentary by Christopher Warnock, the leading astrological magician and examples of talisman elections using Thabit's methods.

De Imaginibus, "On Images" is, after Picatrix, the most important text for medieval and Renaissance astrological magic. De Imaginibus was written in the 9th century A.D. by Thabit Ibn Qurra and represents the height of astrological magic technique, using the full range of traditional astrological technique developed by the sophisticated Harranian Sabians. De Imaginibus explains how to create house based talismans, how to use horary questions to forecast and anchor talismans and how to tune talismans to individual natal charts. This edition contains the first ever English translation and commentary by the noted contemporary astrological magician, Christopher Warnock, as well as illustrations by the artist and contemporary mage Nigel Jackson.
