This article reassesses the reasons why Toledo achieved prominence as a center for Arabic-Latin translation in the second half of the twelfth century, and suggests that the two principal translators, Gerard of Cremona and Dominicus Gundissalinus, concentrated on different areas of knowledge. Moreover, Gerard appears to have followed a clear program in the works that he translated. This is revealed especially in the Vita and the “commemoration of his books” drawn up by his students after his death. A new edition (...) of the Vita, Commemoratio librorum and Eulogium, based on all the manuscripts, concludes the article. (shrink)

The history of dynasties and the reigns of kings can be shown to conform to certain recurring astrological configurations or periods of years in the past and can be extrapolated into the future. The various recurring periods are provided, as they are described by Abu Ma‘shar in his Book on Religions and Dynasties (On the Great Conjunctions), and then the application of these doctrines to Bohemian history is illustrated.

Adelard of Bath was one of the most colourful personalities of the Middle Ages. He travelled to the Crusader kingdoms, to Sicily and south Italy, and translated texts on astronomy, astrology and magic from Arabic into Latin. He acquired a lasting reputation as a pioneering mathematician, and he was a gifted teacher. He addressed one of these works, on cosmology and the astrolabe, to the future King Henry II, and it is in the context of the education of the nobility (...) that the three works edited in this book are to be viewed. Adelard meant them to be both entertaining and instructive. They deal with all kinds of topics, from the nature of the soul to the cause of earthquakes, from the effects of music to how to train a hawk. A preface provides the results of research on Adelard's life and work. (shrink)

The formative period of Latin and Hebrew astrology occurred virtually simultaneously in both cultures. In the second quarter of the twelfth century the terminology of the subject was established and the textbooks which became authoritative were written. The responsibility for this lay almost entirely with two scholars: John of Seville for the Latins, and Abraham ibn Ezra for the Jews. It is unlikely to have been by coincidence that the same developments in astrology occurred in these two cultures. John of (...) Seville and Abraham ibn Ezra were both brought up within the Islamic culture of Spain, and their astrology was Arabic astrology. Moreover, some scholars have thought that John’s origins were Jewish, while Ibn Ezra is known to have collaborated with Latin scholars . It cannot be a coincidence that they forged the science of astrology for their respect co-religionists at almost the same time. Yet, very little research has been done on the possible relations between the two scholars. The purpose of this paper is to begin to explore this relationship, and to illustrate it in particular by their shared doctrine concern the location of pain. (shrink)

SummaryThis paper reassesses the importance of the Benedictine monasteries of St Benoît of Fleury and St Mesmin of Micy (both on the outskirts of Orléans), and the Cathedral of Chartres for the early diffusion of Arabic learning concerning the astrolabe, and it relates this diffusion to that of the judicial astrology of ‘Alchandreus philosophus’ and the astronomical tables of the Preceptum canonis Ptolomei. Evidence is given for the fact that already, by the turn of the millennium, the elements were in (...) place for a corpus of a new, mathematically based, practical science of the stars, consisting of works partly of Arabic and partly of Greek inspiration. This corpus was progressively revised and inspired, in turn, further translations from Arabic, until it reached its most mature form in the mid-twelfth century. Until recently, scholarship has tended to concentrate on the cathedral schools of North-east France and Lotharingia, and the monastic schools of South Germany, and to see Gerbert d'Aurillac, the Archbishop of Reims, as the pivotal figure. While these schools were undoubtedly important in the diffusion of the new science of the stars in the eleventh century, it is argued that a key role in the initial stages of the diffusion was played by the interrelated centres of Fleury, Micy and Chartres at the beginning of the century, and Gerbert may not have contributed as much as has been believed. Additional sections are devoted to the authorities in this corpus, ‘King Ptolemy’ and ‘Alchandreus’. A reworking of the Arabic material on the construction of the astrolabe by Ascelin of Augsburg was copied into this corpus. The text has previously been known from only one manuscript; a new edition, from five manuscripts, is provided here, together with a translation and commentary. (shrink)

Abū Ma'shar and al-Qābīsī were active astrologers and defenders of the scientific character of their discipline. They wrote works on criticisms brought forward against the discipline and challenged practitioners whom they considered as detrimental for the esteem and future fate of their science. Nevertheless, both writers can be seen as heirs to a single tradition of thought, which took its origins in Ptolemy's Tetrabiblios and developed largely independently of the religious or philosophical beliefs of a specific community. The arguments developed (...) for proving the scientific value of astrology are interesting in their own right, and merit further study not only by historians of science but also by historians of philosophy.

This collection of essays reflects the wide range of David Pingree's expertise in the scientific texts of Ancient Mesopotamia, Greece, India, Persia, and the medieval Arabic, Hebrew and Latin traditions. Both theoretical aspects and the practical applications of the exact sciences-in time keeping, prediction of the future, and the operation of magic-are dealt with. The book includes several critical editions and translations of hitherto unknown or understudied texts, and a particular emphasis is on the diffusion of scientific learning from one (...) culture to another, and through time. Above all, the essays show the variety and sophistication of the exact sciences in non-Western societies in pre-modern times. (shrink)

These volumes present the text of Abū Ma’͑šar’s _Great Introduction to Astrology_ in Arabic and Greek and the divergences in the Latin translations. It provides a fully-comprehensive account of traditional astrological doctrine and its philosophical bases.

These volumes provide the Arabic, Latin and English versions of the major text on political astrology of the Middle Ages, generally attributed to Abū Ma‘šar , with a commentary and Latin-Arabic and Arabic-Latin glossaries.
