Published in memory of Prof. Claudia Barsanti, Archaeology of a World of Changes provides a selection of papers presented in sessions on Late Roman and Early Byzantine archaeology, architecture, sculpture and landscapes of the 23rd International Congress of Byzantine Studies, "Byzantium - A World of Changes" (Belgrade, 22-27 August 2016). The variety of topics in archaeology and art history that are discussed in this volume illustrates the richness of material culture in the Roman East and the Eastern Mediterranean during the transition to the Middle Ages, especially in Greece and the Balkans. Christian buildings, not only churches but also episcopal palaces, along with their architecture and decoration, receive special attention. Indeed, the volume includes the complete proceedings of a round table on the historical development, the architectural typologies and the domestic spaces of bishops' residences which took place at the Congress.
