As has been noted:
Caesar. Who is it in the press that calls on me?
I hear a tongue, shriller than all the music,
Cry 'Caesar!' Speak; Caesar is turn'd to hear.
Soothsayer. Beware the ides of March.
Caesar. What man is that?
Brutus. A soothsayer bids you beware the ides of March.
Caesar. Set him before me; let me see his face.
Cassius. Fellow, come from the throng; look upon Caesar.
Caesar. What say'st thou to me now? speak once again.
Soothsayer. Beware the ides of March.
Caesar. He is a dreamer; let us leave him: pass.
