The One Not Born of Woman

Act 4, scene 1. This is when Macbeth going to the witches once again, mistake going at all, to talk to them about his future. At the moment he is paranoid about himself and his security is low, this explaining why he wishes to hear from the witches after their first apparition coming true. The witches then inform him the second apparition which was that none of woman born shall harm him. Being in the 11th century, I wouldn't have worried about this, who was I to believe that one was able to not be born of a woman. Last time I checked the first cesarean section was about in the 1500s... unless Macduff was in reality the first one to be born of c section. Interesting.
