Abstract
Augustine was a writer who carefully observed and consciously tried to influence the reception of his own works. In order to achieve this he employed three different but closely interrelated means: 1) the text of the books itself; 2) their media, which, in Augustine’s time, primarily means the codex; but oral elements are also important, because the usual way of book production was dictation and readers were usually listeners; 3) the public advertising of the writings in Augustine’s letters. In the case of De civitate Dei, a rigid textual structure, a carefully planned distribution of the immense text on a fixed number of codices and the exceptional method of publication in installments combine to create the impression of an authoritative, all-encompassing and conclusive account of Christian apologetics that literally appears to be codified from the outset. By contrast, De trinitate is inscribed into the literary tradition of the maieutic dialogue. Augustine goes to great lengths to give the written text an air of orality and to make it appear as a joined enterprise of himself and his reader the results of which need, and are subjected to, continuous revision. When, after the first twelve books had been published against his will, a great portion of the text was no longer open to correction, Augustine largely abandoned the fiction of orality and shifted the emphasis from the process of inquiry to the results achieved.
