Institutio Oratoria

On the other hand, it will sometimes also happen that an audience whose taste is bad will fail to award the praise which is due to the most admirable utterances. Reading, however, is free, and does not hurry past us with the speed of oral delivery; we can reread a passage again and again if we are in doubt about it or wish to fix it in the memory. We must return to what we have read and reconsider it with care, while, just as we do not swallow our food till we have chewed it and reduced it almost to a state of liquefaction to assist the process of digestion, so what we read must not be committed to the memory for subsequent imitation while it is still in a crude state, but must be softened and, if I may use the phrase, reduced to a pulp by frequent re-perusal.

For a long time also we should read none save the best authors and such as are least likely to betray our trust in then, while our reading must be almost as thorough as if we were actually transcribing what we read. Nor must we study it merely in parts, but must read through the whole work from cover to cover and then read it afresh, a precept which applies more especially to speeches, whose merits are often deliberately disguised.

For the orator frequently prepares his audience for what is to come, dissembles and sets a trap for them and makes remarks at the opening of his speech which will not have their full force till the conclusion. Consequently what he says will often seem comparatively ineffective where it actually occurs, since we do not realise his motive and it will be necessary to re-read the speech after we have acquainted ourselves with all that it contains.
