Act III, Scene 1, whom does Antony refer to when he says, " The choice and master spirits of this age"? Julius Caesar by William Shakespeare
After Brutus and the other conspirators have slain Julius Caesar, Brutus instructs them to wipe their hands and their swords in Caesar's blood prior to their going out into the streets of Rome to speak to the people. However, before they reach the streets to explain to the Romans what has happened, a servant of Marc Antony approaches them with flattery before reciting his master's request to speak with all of them. When Brutus agrees, Cassius, however, considers killing Antony.
In the first scene of Act III of Julius Caesar as Antony arrives, he speaks first to Caesar, addressing him as "shrunk to this little measure" and bids him farewell. Then, he tells Brutus and the other assassins that he does not know what they intend to do, and whom else they consider corrupt, but he is ready to die as it is a good hour since their swords are covered with Caesar's noble blood. For, Antony says, there is no better place to die than by Caesar. Antony tells the conspirators that he cannot imagine a better death than being stabbed by them, and with hyperbole, he calls them "The choice and master spirits of this age," the masters of their era.
It is, of course with irony that Marc Antony tells Brutus and the conspirators that they are in control of Rome and what has occurred. For, if he attains permission to give a funeral oration for his noble friend, Caesar, Antony intends to foment the crowd and stir them to rebellion. Dissembling, Antony shakes each one's bloody hand when Brutus gives him permission.
