As it comes mere moments before the murder, the speech adds much irony to the scene: having just boasted that he is “unassailable,” Caesar is shortly assailed and killed. In announcing his “constancy,” Caesar claims permanency, immortality even. The assassins quickly prove Caesar mortal, however. But as the later events of the play reveal, Caesar’s influence and eternality are undeniable. His ghost seems to live on to avenge the murder: Brutus and Cassius directly attribute much of their misfortune to Caesar’s workings from beyond the grave; so, too, does the name “Caesar” undergo metamorphosis from an individual man’s name to the title of an institution—the empiric rule of Rome—by the end of the play. In these more important ways, Caesar’s lofty estimation of himself proves true.
