What do the three witches foretell in act one scene 3?
Macbeth has three "weird sisters". In the Folio copy, there are
not only the three witches but a fourth, called Hecat, who is their
boss. In addition, during the Cauldron Scene, a stage direction
says "enter Hecat, and the other three witches" which would make
seven witches all told. However, the character of Hecat is very
silly and is always cut when this play is actually performed.
