Any fan of Shakespeare could easily interpret his use of monsters and the roles that they play in literature. Shakespeare’s themes of monsters usually lead his audience into seeing the horror of what is unfolding in the play. It also offers help to better understand the main parts of the play that may lead to the downfall of a particular character. In his play Macbeth, the “monsters” are the three witches. Unlike most monsters, the witches are not killers; however they are still the most dangerous characters in the play because of their power and wickedness. The Weird Sisters or Three witches are the first characters that appear in Macbeth, and their words in the beginning act, “Fair is foul, and foul is fair; Hover through the fog and filthy air.(1.1.1-13)set the supernatural mood for the whole story and their malevolent intentions. Whether or not they are the cause of King Macbeth’s downfall and homicidal propensities is controversial, but it is certain they used their sorcery to impact him. There is a huge debate on what the main representation of the witches are mainly because their existence in the play can be depicted several ways by readers. The witches play a major role in the play; they represent the cultural values of the Elizabethan age, they represent fate, and they represent the hidden darkness, weaknesses, and evil in humans. The witches represent fate. In the 19th Century, “weird” did not have the meaning it has today. It meant Destiny or Fate (Dave Wilton, February 17, 2007). Fate and foreknowledge is clearly the sister’s role. In the play, the sisters give Macbeth three prophecies. The prophecies show that they are not just trying to manipulate Macbeth, but they can also see into his future. The first prophecy is about Macbeth becoming king. However, the sisters are able to predict that Macbeth will be killed by someone not born of woman. This validates that the sisters are not just guessing Macbeth’s fate, but they already know what is going to happen. Macbeth and his wife took the sister’s words and let them control them. They became different people, or perhaps their true selves as a result of the prophecies. Malcolm vouches for this
