Shakespeare's Julius Caesar is about the political intrigue surrounding the assassination of the Roman dictator in 44 B.C. The main characters include Caesar, his ally Marc Antony and the main plotters against Caesar, Brutus and Cassius. Shakespeare, of course, is the master of figurative language and Julius Caesar has several metaphors. Here are five examples from Act I.
In Act I, Scene 1, the tribune Marellus compares the men who have come to worship Caesar to blocks and stones, because they are as unthinking as those objects: "You blocks, you stones, you worse than senseless things". Marellus and Flavius are against Caesar because he has recently defeated Pompey, and they were supporters of that Roman leader.
Later in Scene 1, Flavius compares Caesar to a bird who would "soar above" the masses and take away their freedoms. He says that bird must be "plucked":
These growing feathers plucked from Caesar’s wing
Will make him fly an ordinary pitch,
Who else would soar above the view of men
And keep us all in servile fearfulness.
Many Romans were afraid that Caesar would bring an end to the Republic and that he would prove to be a ruthless dictator.
In Scene 2, the conspirator Cassius attempts to convince Brutus that Caesar has grown too powerful. Because Brutus is well respected in Rome, Cassius believes he is the best man to lead a rebellion. Cassius compares Caesar to a carnivorous predator feeding on the meat of power:
Upon what meat doth this our Caesar feed
That he is grown so great?
A little later in Scene 2 Caesar, understanding that Cassius may be against him, compares the man to a hungry wolf. Caesar prefers those who are less ambitious:
Let me have men about me that are fat,
Sleek-headed men and such as sleep a-nights.
Yond Cassius has a lean and hungry look.
He thinks too much. Such men are dangerous.
Finally, when Casca explains to Brutus and Cassius that Caesar has epilepsy, or the "falling sickness" Cassius denies it, but admits that he and the other conspirators will have it because they will fall from power:
No, Caesar hath it not. But you and I
And honest Casca, we have the falling sickness.
