This volume makes available two hitherto unpublished Latin texts on astronomical tables, written by Abraham Ibn Ezra and Robert of Chester, which together shed new light on the mid-twelfth-century assimilation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

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.

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.

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.
