The rhetoric of Roman moralising has often seemed alien to modern readers. This book, in linking together studies of apparently diverse topics, might be seen as appropriating a trope of Roman moralistic discourse, presenting arguments concerning different subjects as parallel so that they may serve to reinforce one another.

We begin with an apparently bizarre example of this kind of rhetoric (included in the book of rhetorical exercises put together by the elder Seneca).
