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.

This volume comprises a multidisciplinary study of Pisa’s socio-economic, cultural, and political history, art history, and archaeology at the time of the city’s greatest fame and prosperity during the transformative period of the Middle Ages.

Recent historical research and new perspectives on the Islamic scientific tradition.

The Crusades had a wide variety of impacts on societies throughout Europe, Asia, and Africa. One such notable impact was its role in the development of knowledge between cultures. This book argues that the Nubian kingdom of Dotawo and the Latin Christians became increasingly more connected between the twelfth and early fourteenth centuries than has been acknowledged. Subsequently, when Solomonic Ethiopian-Latin Christian diplomatic relations began in 1402, they were building on the prior connections of Nubia, either wittingly or unwittingly: Ethiopia became the ‘Ethiopia’ that the Latin Christians had previously been aiming to develop relations with. The histories of Nubia, Ethiopia, and the Crusades were directly and indirectly entwined between the twelfth century and 1402. By placing Nubia and Ethiopia within the wider context of the Crusades, new perspectives can be made regarding the international activity of Nubia and Ethiopia between the twelfth and fifteenth centuries and the regional role reversal of Dotawo and Solomonic Ethiopia from the early fourteenth century. Prior to the fourteenth century, Nubia had been the dominant Christian power in the region before Solomonic Ethiopia began to replace it, including by adopting elements of discourse which had previously been attributed to Nubia, such as its ruler being the recognised protector of the Christians of north-east Africa. This process should not be viewed in isolation of the wider regional geo-political context. Nubia, Ethiopia, and the Crusading World, 1095-1402 will appeal to all those interested in the history of the Crusades, Nubia, and Ethiopia, particularly concerning inter-regional physical and intellectual connectivity.

How were the relations among image, imagination and cognition characterized in the period 1500 – 1800? The authors of this volume argue that in those three centuries, a thoroughgoing transformation affected the following issues: (i) what it meant to understand phenomena in the natural world (cognition); (ii) how such phenomena were visualized or pictured (images, including novel types of diagrams, structural models, maps, etc.); and (iii) what role was attributed to the faculty of the imagination (psychology, creativity). The essays collected in this volume examine the new conceptions that were advanced and the novel ways of comprehending and expressing the relations among image, imagination, and cognition. They also shed light, from a variety of perspectives, on the elusive nexus of conceptions and practices.

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 essays in this volume reflect the wide-ranging interests of John D. North, distinguished historian of science and philosophy. Section One has papers on horoscopes, astrolabes and time-reckoning, and it includes an edition of a twelfth-century treatise on the astrolabe and surveys of astrolabes. Section Two is devoted to the study of the medieval cosmos. These contributions discuss Calcidian astronomy, astronomy in the Spanish Jewish community, the role of God in scholastic natural philosophy, and other themes. New information is presented about previously unknown scholars such as Abd al-Masīḥ of Winchester and Simon Bredon. Section Three contains essays on philosophy and scholarship in the early modern period, including pieces about commentaries on Boethius’s Consolatio Philosophiae in the Northern Renaissance, Spinozistic philosophy, and the early modern concept of substance. These essays take up the various themes to which John D. North has made important contributions: the development of scientific knowledge and methodology, the style of scientific and philosophical thought, and the uses of scientific knowledge in the making of instruments or the casting of horoscopes: this book will be of much interest to all historians of science and philosophy.
