<P> In the political rise of the Roman Republic, Roman orators copied and modified the ancient Greek techniques of public speaking . Instruction in rhetoric developed into a full curriculum, including instruction in grammar (study of the poets), preliminary exercises (progymnasmata), and preparation of public speeches (declamation) in both forensic and deliberative genres . </P> <P> The Latin style of rhetoric was heavily influenced by Cicero and involved a strong emphasis on a broad education in all areas of humanistic study in the liberal arts, including philosophy .
