And Antony (mark you) agrees and promises and breaks his promise
immediately afterwards. Maybe he was only gaining time for his good
friend Octavius Caesar, but time gained by such foul means is time
lost through all eternity. Did Mark think of these things years
afterwards in Egypt when he was doubly ruined and doubly betrayed to
his good friend Octavius by that hot, jealous, selfish, shallow,
shifty, strumpet, Cleopatra, and Octavius was after his scalp with a
certainty of getting it? He did--and he spoke of it, too.

Brutus made his speech, a straightforward, manly speech in prose,
and the gist of the matter was that he did what he did (killed Caesar),
not because he loved Caesar less, but because he loved Rome more.
And I believe he told the simple honest truth.

Then he acts as Antony's chairman, or introducer, in a manly
straightforward manner, and then he goes off and leaves the stage to
him, which is another generous act; though it was lucky for Brutus, as
it happened afterwards, that he was out of the way.

Mark Antony gets all the limelight and blank verse. He had the "gift
of the gab" all right. Old Cassius referred to it later on in one of
those "words-before-blows" barneys they had on the battlefield where
they hurt each other a damned sight more with their tongues than they
did with their swords afterwards.

We've all heard of Antony's speech:

I come to bury Caesar, not to praise him.

Which was a lie to start with.
