In Jacobean England, there was a widespread belief in witches and witchcraft
They were seen as agents of Satan, many women were executed in suspicion of being witches
King James and Jacobean audiences were fascinated by the presentation of witches on stage, but would know to distrust them.
The witches should then be seen as untrustworthy and malevolent
The witches are also shown to be capable of affecting the weather, creating spells and committing acts against ordinary people
