Moreover, a narrative allows the narrator to portray an exceptional situation as acceptable and to insert various voices without the risk of seeming inconsistent. Stereotypes can also play a subtle and persuasive role in a story. This article will show how Cicero, in his defence of Roscius Amerinus, has used all these narrative techniques.
