The American heritage dictionary defines the word supernatural as an, "existence relating to outside of the natural world" (Dell 825). In the play Mac Beth, William Shakespeare uses the supernatural to captivate the audiences' attention. While the play would have the same plot without these elements, it just would not be as interesting.
The play, Romeo and Juliet has the chorus set up the plot and in Macbeth the supernatural does the job. In essence, to captivate the audience's attention, instead of using the expected or the norm, Shakespeare uses three witches.
1st Witch When shall we three meet again
2nd Witch When the hurlyburly's done,
3rd Witch That will be ere the set of sun.
3rd Witch There to meet Macbeth (1.1.1-8 ).
In Act 1 Scene 1, Shakespeare uses the three witches to set a dialogue to foreshadow the coming events in the play. "When the hurlburly's done/When the battle is lost and won (1.1.3-4 ). This line lets the audience/readers know that the play is centered around battle and most likely will have soldiers as characters. In addition, this battle will be ended by sundown, "That will be ere the set of sun"(1.1.5). Furthermore, the main character will likely be Macbeth because he is the only name mentioned. "There to meet Macbeth"(1.1.8).
Two scenes later in Act 1 Scene 3 Macbeth and his companion Banquo meet the Witches. Upon seeing the witches Banquo states:
How far is't called to Forres?
So withered, and so wild in their attire,
That look not like th'inhabitants o'th'earth,
And yet are on't? Live you? or are you aught
That man may question? You seem to understand me,
By each at once her choppy finger laying
Upon her skinny lips: you should be women,
And yet your beards forbid me to interpret/ That you are so (1.3.39-47).
Here we see that Banquo questions what is right in front of e...
