In the prologue to the Rhetorica ad Herennium book 4, Cornificius boldly departs from tradition: he will create his own examples to illustrate styles and figures of rhetoric, rather than drawing from poets and orators, as Greek manuals typically did. This methodological discussion, which resembles a declamation, portrays itself as an exemplum in that it embodies the precepts exposed in books 1, 2, and 3. Moreover, this exemplary discussion partakes in a larger debate between philosophy and rhetoric and must be considered in its historical and cultural context.
