How are classical rhetorical devices used differently in Brutus' and Antony's speeches in Shakespeare's Julius Caesar?

Brutus uses the schemes of repetition and parallelism to strengthen his message, appealing to the audience's sense of ethos (credibility) and logos (logic) with a notion of his honour and high standing. In contrast, Antony uses irony alongside parallelism to gradually build doubt towards Brutus' honour in the minds of the audience, while initially seeming to agree with him.
