Sad to report the death of Robert Markus, the medieval historian who did as much as anyone, along with his friend and occasional academic rival Peter Brown, to help define late antiquity:
Robert Markus, who has died of cancer at the age of 86, was among the finest historians of his generation. He helped establish the idea of Late Antiquity as a distinct and exceptionally creative period of European history, bridging the fall of the western Roman Empire and the early Middle Ages. He stressed the importance of Christianity's beliefs, but always had an eye to the material and social structures in which it was practised.
