Peter Robert Lamont Brown, FBA, (born 26 July 1935) is Rollins Professor of History Emeritus at
Princeton University. He is credited with having created the field of study referred to as
Late Antiquity: the period during which Rome fell, the three major monotheistic religions took shape, and Christianity spread across Europe. His work has concerned, in particular, the religious culture of the later
Roman Empire and early
medieval Europe, and the relation between religion and society.
