Evolving from a patrician domus, the emperor's residence on the Palatine became the centre of the state administration. Elaborate ceremonial regulated access to the imperial family, creating a system of privilege which strengthened the centralised power. Constantine followed the same model in his new capital, under a Christian veneer. The divine attributes of the imperial office were refashioned, with the emperor as God's representative. The palace was an imitation of heaven. Following the loss of the empire in the West and the Near East, the Palace in Constantinople was preserved - subject to the transition from Late Antique to Mediaeval conditions - until the Fourth Crusade, attracting the attention of Visgothic, Lombard, Merovingian, Carolingian, Norman and Muslim rulers. Renaissance princes later drew inspiration for their residences directly from ancient ruins and Roman literature, but there was also contact with the Late Byzantine court. Finally, in the age of Absolutism the palace became again an instrument of power in vast centralised states, with renewed interest in Roman and Byzantine ceremonial. Spanning the broadest chronological and geographical limits of the Roman imperial tradition, from the Principate to the Ottoman empire, the papers in the volume treat various aspects of palace architecture, art and ceremonial.

Professor Spieser deals here with a number of the transformations that took place in the world of Late Antiquity - and early Christianity - focusing upon notions of space. The first set of articles, opening with a newly-written introductory essay, addresses the development of urban landscapes from the Roman period up to the iconoclast era in Byzantium. In particular, he looks at the consequences of christianisation, and argues that the changing fortunes of the town cannot be attributed to a few causes, such as war or natural disaster, but resulted from a complex interplay between the economy and ideology, religion and politics. A second group, concerned with the relationship of 'late antique' man with his surroundings, and therefore his perception of space, sets out to explain how the decoration of churches - on apses, for example, or on doors - reflects new senses of how religious spaces should be organised. Six of these studies have been translated into English for this volume, and it ends with an important section of additional notes and comment.
