Book excerpt: Based on close analyses of contemporary texts, and backed by an examination of the origins of the elements transferred and of the process of transmission, the contributors to this volume focus on the perception and adaptation of knowledge and cultural elements in the West. Taking a variety of approaches, they shed light on the changing lines of communication between the Byzantine empire and other parts of the Mediterranean, on the one hand, and the Burgundian, Frankish and Anglo-Saxon realms and the Papacy on the other.
