The city was one of the central and defining features of the world of the Greek and Roman Mediterranean. Challenging the idea that the ancient city 'declined and fell', Andrew Wallace-Hadrill argues that memories of the past enabled cities to adapt and remain relevant in the changing post-Roman world. In the new kingdoms in Italy, France and Spain cities remained a key part of the structure of control, while to contemporary authors, such as Cassiodorus in Ostrogothic Italy, Gregory of Tours in Merovingian Gaul, and Isidore in Visigothic Spain, they remained as crucial as in antiquity. The archaeological evidence of New Cities founded in this period, from Constantinople to Reccopolis in Spain, also shows the deep influence of past models. The Idea of the City in Late Antiquity: A Study in Resilience (Cambridge UP, 2025) reveals the adaptability of cities and the endurance of the Greek and Roman world. Sheds fresh light on one of the most important social and cultural developments in the transition from classical antiquity to the world of the Middle Ages Explores developments through the eyes of contemporary writers and documents as well as the archaeological record Of interest to all those concerned with how cities can adapt in a radically changing world ANDREW WALLACE-HADRILL is Emeritus Professor in the Faculty of Classics at the University of Cambridge and an Emeritus Fellow of Sidney Sussex College.
