"Memoria" was the discipline of recalling the arguments of a discourse. It generally received less attention from writers than other parts of rhetoric, as there is less to be said about the subject. However, the need to memorize speeches did influence the structure of discourse to some extent. For example, as part of "dispositio", some attention was paid to creating structures (such as the "divisio", an outline of the major arguments of a discourse) that would also aid memory. Some writers also discussed the use of various mnemonic devices to assist speakers.
