A good part of this work, of course, deals with the technical aspects of rhetoric and the "Institutio Oratoria" stands — along with Aristotle's 'Rhetoric' and Cicero's works — as one of the ancient world's greatest works on rhetoric. He organizes the practice of oratory into five canons: "inventio" (discovery of arguments), "dispositio" (arrangement of arguments), "elocutio" (expression or style), "memoria" (memorization), and "pronuntiatio" (delivery). For each canon, particularly the first three, he provides a thorough exposition of all the elements that must be mastered and considered in developing and presenting arguments. The thorough and sensible presentation reflect his long experience as orator and teacher, and in many ways the work can be seen as the culmination of Greek and Roman rhetorical theory.
