inventio a minor by bach (BWV 784)

The word "invention" goes all the way back to the ancient Romans. It comes from the Latin verb invenire, which is literally "to come upon; to find". An inventio was "a finding; something found".

Cicero's five canons of rhetoric are: inventio (invention), dispositio (arrangement), elocutio (style), memoria (memory), and pronuntiatio (delivery). These canons outline the basic steps for effective communication and persuasion.
