Cicero
De Oratore (55 B.C.)
Rhetoric Timeline
Primary Source Synopses

Of Cicero's rhetorical treatises De Oratore, "On the Orator," was the most sophisticated treatment of rhetorical doctrines, surpassing his youthful De Inventione, which was more consistent with the rudimentary and systematic rhetoric, Rhetorica ad Herennium, that for so long was attributed to him. All of these are vital texts in establishing ancient Roman rhetorical doctrine, but De Oratore problematized the issues at the base of rhetoric by embodying them in dialogue form.
