Because ancient writers spoke as they wrote, their texts were understood to have oracular quality. Authors, limited by the convention of scriptio continua (the practice of writing words, frequently abbreviated, without spaces and punctuation), were careful to supply their readers with aural clues of textual structure, clarifying their emphases by various means of repetition. Readers listened for the writer's ‘voice’: for clues of aural structures – rhetorical devices (anaphora, inclusio, antithesis, etc.), for enthymemes and topoi in deductive reasoning and for examples in inductive reasoning – even as they voiced the words of the text. ‘Reading’, as Paul J. Achtemeier points out, ‘was … oral performance whenever it occurred and in whatever circumstances. Late antiquity knew nothing of the “silent, solitary reader”’ (original emphasis).
