Commonly referred to as the "weird sisters" or the "Wayward sisters"
Portrayed as supernatural beings by Shakespeare
Give Macbeth many cryptic prophecies
Shakespeare introduces the Witches in the first scene of the play, thus giving special emphasis to their importance
"Fair is foul, and foul is fair"
A paradoxical phrase that foreshadows the rest of the play
"Weird Sisters"
Bears connotations of "wired" meaning fate in Old English, associating their speech with prophecy
Appealing to James I
Shakespeare uses the character of the Witches in order to appeal to the current monarch James I, who had a passion for the history of witchcraft
Shakespeare portrays the Witches as inherently evil and agents of Satan to appeal to James I
Shakespeare had the motive of wanting to make the play interesting to James so that he will financially support the theatre and ensure patronage
Through presenting regicide as inspired or even controlled by the Witches, Shakespeare implies it is related to the devil and hence regicide will have severe religious consequences
Macbeth is aligned with forces of supernatural evil within the play, and association with the supernatural will always result in suffering and severe consequences
The Witches' direct influence upon the Macbeths is evidenced through the link between Macbeth and Lady Macbeth's lack of sleep
Supernatural
The rhythmic and chant-like nature of the Witches' rhetoric implies that their words have real extraordinary power
Macbeth and Lady Macbeth also speak in rhyming couplets at timeswhen they are expressing evil or when they are controlled by the supernatural
Trochaic Tetrameter
The shift in meter between the characters places importance on what is being said, causingthe witches to stand out as different and other-worldly
Rhyming Couplets
Gives the Witches' speech a spell-like sound, symbolic of spell casting and bringing things into existence through their utterances
Witches were believed to be unable to directly kill man, so instead they had to control others to create disorder and chaos
The Witches' prophecies
Cause Macbeth to realise his own ambitions and inspire him to act upon them
Macbeth
May be a greater force of evil than the Witches as he physically carries out the act of regicide
The Witches
May be a catalyst for Macbeth's actions, but his desire for power provides the momentum
Banquo
Is also affected by the Witches, as he admits to dreaming of them
Banquo's response shows the Witches can be resisted and they do not have complete control
Lady Macbeth
Can be interpreted as a fourth witch, of perhaps an even greater evil
Lady Macbeth
Uses linguistic mimicry of the Witches' form of speech, connecting her to their inherent evil
The Witches are described as "imperfect speakers"
They speak in riddles that are meant to be misunderstood, but Macbeth chooses to ignore this as his greed for power overcomes him
