This illustrated book is a coherently conceived collection of interdisciplinary essays by distinguished authors on the city of Rome and its contacts with western Christendom in the early Middle Ages (c. 500-1000 AD). The first part integrates historical, archaeological, numismatic and art historical approaches to studying the transition of the city of Rome from Antiquity to the Middle Ages and offers groundbreaking new analyses of selected sites and problems. Attention is given to the economic, social, religious and cultural history of the city. In the second part of the volume historical, archaeological, liturgical and palaeographical approaches address Rome's contacts and influence in Latin Christendom in this period, with particular regard to Rome's place within Italian politics and its cultural influence in Carolingian Francia and Anglo-Saxon England.
