Looking back on his first encounters withAmbrose, Bishop of Milan, in the late fourth century, Augustineremembers noticing the curious way Ambrose would read: ‘his eyeswould scan over the pages and his heart would scrutinize theirmeaning – yet his voice and tongue remained silent’.7 This –reading in silence – is not normal, and Augustine wonders whatcould possess Ambrose to adopt such a practice. (Was it to preservehis voice? Or a way of avoiding unwanted discussions about the texthe was reading?)
