IV. I should not venture to speak of artistic structure Composite in its widest sense means artistic structure. But in much of what follows it virtually = rhythm. after what Cicero has said upon the subject (for there is I think no topic to which he has devoted such elaborate discussion) but for the fact that his own contemporaries ventured to traverse his theories on this subject even in letters which they addressed to him, while a number of later writers have left on record numerous observations on the same topic.

Accordingly on a large number of questions I shall be found in agreement with Cicero and shall deal more briefly with those points which admit of no dispute, while there will be certain subjects on which I shall express a certain amount of disagreement. For, though I intend to make my own views clear, I shall leave my readers free to hold their own opinion.
