Distinguished Latinist Elaine Fantham’s commentary is noteworthy for its ability to elucidate not only the rhetorical structure of this speech but the rationale behind Cicero’s strategic decisions in creating that structure. It also calls attention to the stylistic features like word choice, rhetorical figures, and rhythmic effects that make the speech so effective, and explains with care and precision the political, social, and historical considerations that shaped the prosecution and defense of the somewhat hapless defendant. This commentary includes the kind of grammatical explication required to make its riches accessible to undergraduate students of Latin.
