This volume makes available two hitherto unpublished Latin texts on astronomical tables, written by Abraham Ibn Ezra and Robert of Chester, which together shed new light on the mid-twelfth-century assimilation of Graeco-Arabic mathematical astronomy in Christian Europe.

The Gregorian calendar reform of 1582, which provided the basis for the civil and Western ecclesiastical calendars still in use today, has often been seen as a triumph of early modern scientific culture or an expression of papal ambition in the wake of the Counter-Reformation. Much less attention has been paid to reform's intellectual roots in the European Middle Ages, when the reckoning of time by means of calendrical cycles was a topic of central importance to learned culture, as impressively documented by the survival of relevant texts and tables in thousands of manuscripts copied before 1500. For centuries prior to the Gregorian reform, astronomers, mathematicians, theologians, and even Church councils had been debating the necessity of improving or emending the existing ecclesiastical calendar, which throughout the Middle Ages kept losing touch with the astronomical phenomena at an alarming pace. Scandalous Error is the first comprehensive study of the medieval literature devoted to the calendar problem and its cultural and scientific contexts. It examines how the importance of ordering liturgical time by means of a calendar that comprised both solar and lunar components posed a technical-astronomical problem to medieval society and details the often sophisticated ways in which computists and churchmen reacted to this challenge. By drawing attention to the numerous connecting paths that existed between calendars and mathematical astronomy between the Fall of Rome and the end of the fifteenth century, the volume offers substantial new insights on the place of exact science in medieval culture.

This is the first reference ever devoted to medieval philosophy. It covers all areas of the field from 500-1500 including philosophers, philosophies, key terms and concepts. It also provides analyses of particular theories plus cultural and social contexts.

Mediterranean studies flourish in literary and cultural studies, but concepts of the Mediterranean and the theories and methods they use are very disparate. This is because the Mediterranean is not a simple geographical or historical unity, but a multiplicity, a network of highly interconnected elements, each of which is different and individual. Talking about Mediterranean literature raises the question of whether the connectivity of Mediterranean literature can or should be limited in some way by constructing an inside and an outside of the Mediterranean. What kind of connectivity and fragmentation do literary texts produce, how do they build and interrupt references (to the real, to fictional forms of representation, to history, but also to other texts and discourses), how do they create and deny communication, and how do they engage with and reflect literary and non-literary concepts of the Mediterranean? These and other questions are considered and discussed in the over twenty contributions gathered in this volume.

Issues consist of lists of new books added to the library ; also articles about aspects of printing and publishing history, and about exhibitions held in the library, and important acquisitions.

In the second millennium CE, long before English became the language of science in the twentieth century, the act of translation was crucial for understanding and disseminating knowledge and information across linguistic and geographic boundaries. This volume considers the complexities of knowledge exchange through the practice of translation over the course of a millennium, across fields of knowledge—cartography, health and medicine, material construction, astronomy—and a wide geographical range, from Eurasia to Africa and the Americas. Contributors literate in Arabic, Catalan, Chinese, Greek, Hebrew, Italian, Japanese, Latin, Minnan, Ottoman, and Persian explore the history of science in the context of world and global history, investigating global patterns and implications in a multilingual and increasingly interconnected world. Chapters reveal cosmopolitan networks of shared practice and knowledge about the natural world from 1000 to 1800 CE, emphasizing both evolving scientific exchange and the emergence of innovative science. By unraveling the role of translation in cross-cultural communication, Knowledge in Translation highlights key moments of transmission, insight, and critical interpretation across linguistic and faith communities.

The Renaissance marked a turning point in Europe’s relationship to Arabic thought. On the one hand, Dag Nikolaus Hasse argues, it was the period in which important Arabic traditions reached the peak of their influence in Europe. On the other hand, it is the time when the West began to forget, and even actively suppress, its debt to Arabic culture. Success and Suppression traces the complex story of Arabic influence on Renaissance thought. It is often assumed that the Renaissance had little interest in Arabic sciences and philosophy, because humanist polemics from the period attacked Arabic learning and championed Greek civilization. Yet Hasse shows that Renaissance denials of Arabic influence emerged not because scholars of the time rejected that intellectual tradition altogether but because a small group of anti-Arab hard-liners strove to suppress its powerful and persuasive influence. The period witnessed a boom in new translations and multivolume editions of Arabic authors, and European philosophers and scientists incorporated—and often celebrated—Arabic thought in their work, especially in medicine, philosophy, and astrology. But the famous Arabic authorities were a prominent obstacle to the Renaissance project of renewing European academic culture through Greece and Rome, and radical reformers accused Arabic science of linguistic corruption, plagiarism, or irreligion. Hasse shows how a mixture of ideological and scientific motives led to the decline of some Arabic traditions in important areas of European culture, while others continued to flourish.

In On Both Sides of the Strait of Gibraltar Julio Samsó shows that astronomical sources, written in al-Andalus, the Maghrib and the Iberian Peninsula, belong to the same tradition and emphasizes the role of al-Andalus and the Iberian Peninsula in the transmission of Islamic astronomy to medieval Europe.

This volume aims to make Stephen of Pisa and Antioch’s work on the celestial sciences accessible to a wider readership, providing not just the text but a translation and introduction as well. The edition is based on the only known manuscript of the Liber Mamonis, MS Cambrai, Médiathèque d’Agglomération, A 930. It is split into two parts: the first provides an extensive introduction to Stephen and his work, while the second features the edition and translation. A comprehensive glossary and collection of photographs of plates are also included.
