N.T. Wright quotes Arnaldo Momigliano on Augustus' version of Peace

"And, as Arnaldo Momigliano, one of the greatest of ancient historians, once put it, '[Augustus] gave peace, as long as it was consistent with the interests of the Empire and the myth of his own glory'. There you have it in a nutshell: the whole ambiguous structure of human empire, a kingdom of absolute power, bringing glory to the man at the top, and peace to those on whom his favour rested."
