Antony asks that they allow him to take the body to the marketplace and, further, that he be allowed to orate at the funeral.
Here are the lines Antony delivers to the Servant (who is to take the news to the conspirators):
Post back with speed and tell him what hath chanced.
Here is a mourning Rome, a dangerous Rome,
No Rome of safety for Octavius yet;
Hie hence, and tell him so. Yet stay awhile,
Thou shalt not back till I have borne this corpse
Into the market-place. There shall I try,
In my oration, how the people take
issue of these bloody men,
According to the which thou shalt discourse
To young Octavius of the state of things.
Lend me your hand.
