Brown's success stems from his mastery of and zest for source material, compounded with social insight, carefully digested historiographic and social theory, and a sharp eye for human beings, according to Oxford Don Robin Lane Fox.
Brown, the rambler, born in 1935 in Dublin into a Protestant Irish family, was educated at Aravon School, Bray, County Dublin; Shrewsbury School; and New College, Oxford.
Brown is looking for the mental and social constructs as well as the imaginative boundaries that characterize late antiquity.
