In William Shakespeare's "Macbeth," there are several examples of hyperbole including when Macbeth says,"They crown does scar mine eye-balls" or "This tyrant, whose sole name blisters our tongues." Both of these phrases are examples of hyperbole because they exaggerate something as being more or less than it is.
Readers know that a crown cannot scar eyeballs nor can a person's name blister another person's tongue. This is an exaggeration, which makes it a hyperbole as a literary device.
The story of "Macbeth" follows Macbeth and his wife, Lady Macbeth, as they try to make their way to the throne. Although they ultimately do get the throne, it is at a great cost with Macbeth descending into madness. The two then meet an untimely death.
One of the primary themes in Shakespeare's "Macbeth" is that those who are too ambitious and ignore morality will find nothing but destruction. When the play begins, Macbeth is power hungry yet he has a moral compass that he allows to guide him. Lady Macbeth convinces him that he must kill Duncan in order to become the King immediately. Once Macbeth has killed Duncan and become the king, he feels deep remorse and newfound paranoia. This newfound paranoia makes him consider killing anyone and everyone who irritates or disobeys him. Shakespeare was making the point that when ambition is let loose without any moral guidance, then violence will be used to solve problems.
