Institutio Oratoria

If our statement is to be clear and brief, almost anything can be justified sooner than digression. And if we do introduce a digression, it must always be short and of such a nature that we give the impression of having been forced from our proper course by some uncontrollable emotion. The passage in Cicero [*](pro Clu. vi. 15. ) about the marriage of Sasia is a good example of this.

What incredible wickedness in a woman! Unheard of in the history of mankind till she dared the sin! What unbridled and unrestrained lust, what amazing daring! One might have thought that, even if she had no regard for the vengeance of heaven and the opinion of man, she would at least have dreaded that night of all nights and those torches that lighted her to the bridal bed: that she would have shrunk in horror from the threshold of her chamber, from her daughter's room and the very walls that had witnessed her former marriage.
