The Christianisation of the Roman world lies at the root of modern Europe, yet at the time it was a tentative and piecemeal process. Peter Brown's fascinating study examines the factors which proved decisive and the compromises which made the emergence of the Christian 'thought world' possible: how the the old gods of the Roman Empire could be reinterpreted as symbols to further the message of the Church. Peter Brown also shows how Christian holy men were less representative of a triumphant faith than negotiators of a working compromise between the new faith and traditional ways of dealing with the supernatural worlds.
