Read the excerpt from Act III of Julius Caesar.

Antony: (To dead Caesar, with grief) 0, pardon me, thou bleeding piece of earth, that I am meek and gentle with these butchers. Thou art the ruins of the noblest man that ever lived in the tide of times.

(Looking after the murderers, he shakes his fist at them in fury.) Woe to the hand that shed this costly blood! A curse shall light upon the limbs of men. (He points to Caesar, whose ghost will rise.) And Cae­sar's spirit, ranging for revenge, come hot from Hell, shall in these confines with a monarch's voice cry, "Havoc!" and let slip the dogs of war that this foul deed shall smell above the earth with carrion men, groaning for burial.
