Abstract: For the theme of the representation and perception of Roman imperial power to which this volume is devoted no individual could be more central than Augustus and no aspect of his reign of greater importance than his role as both great conqueror and bringer of peace.In this paper I shall discuss not only the presentation and perception of this aspect of the first emperor, but also the policies which lay behind the presentation. IdeologyAugustus was proclaimed as a great victor in every contemporary medium. 1 The preamble of the Res Gestae declares that what follows records the achievements by which "he subjected the world to the empire of the Roman people" (orbem terrarum imperio populi Romani subiecit).Early in the document (3.1-4.2) Augustus tells us that "I often waged civil and external wars by land and sea throughout the whole world" (bella terra et mari civilia extemaque toto in orbe saepe gessi), and records among other feats his two ovations, three curule triumphs, 21 imperatorial salutations and 55 supplicationes.A later section (26-33) substantiates the preamble's claim of world conquest with a lengthy rehearsal of both military and diplomatic successes.
