During the first half of this century the view came to be widely held by numismatists, and by many Roman historians too, that the types chosen for the Roman imperial coinage were to be interpreted as a means of influencing public opinion, of reconciling his subjects to the rule of the Princeps, and of explaining imperial policy to them; in short, as propaganda. Thus for C.H.V. Sutherland coins are, in essence, ‘organs of information’, while in the words of M. Grant, ‘Roman coinage . . . served a propagandist purpose far greater than has any other national coinage before or since . . . This was the means which the Roman government . . . used to insinuate into every home in the empire each changing nuance of imperial achievement and policy’.
