In Act 3.2 of Shakespeare's Julius Caesar, Antony juxtaposes (places in opposition) an unambitious act performed by Caesar, with a refrain about Brutus's (or the other conspirators') belief that Caesar was ambitious and about Brutus (or the other conspirators) being honorable men. I'll put it in bullets:
- Caesar did an unambitious act
- But Brutus says he was ambitious
- And Brutus is an honorable man
Here's an example from Antony's speech, with the quotes in bullets:
- I thrice presented him a kingly crown,/Which he did thrice refuse. Was this ambition?
- Yet Brutus says he was ambitious,
- And sure he is an honorable man. (Act 3.2.105-108)
Antony uses irony to persuade the crowd that Caesar was not ambitious and was therefore assassinated unjustly, because he earlier promises Brutus that he will not directly say anything negative about the conspirators. He, therefore, says only positive things about the conspirators, but the juxtaposition of Caesar's unambitious acts with those positive things, creates irony.
And it also creates a mob that riots through Rome looking to kill the conspirators.
In his funeral speech in Act III, Scene 2, Marc Antony means to rebut Brutus's claim that Caesar was ambitious. He does it by listing a bunch of things that Caesar did that he does not think showed Caesar being ambitious.
Some examples of this include:
- He captured people in war and brought them back to Rome. Their ransoms put lots of money in Rome's "coffers."
- Caesar sympathized with the poor -- ambitious people don't do that, Antony says.
- Caesar three times refused to be crowned king.
While listing these things, Antony uses irony quite effectively to show that Caesar was not ambitious and Brutus is.
Antony clearly explains that Caesar brought home captives whose ransoms filled the general coffers,Caesar wept along with the poor and Caeser denied the crown when he offered it thrice, these words of Antony clearly shows that Caeser wasn't ambitious.
