-4.1.68-72 "[First Apparition: an Armed Head] 'Macbeth! Macbeth! Macbeth! Beware Macduff! Beware the Thane of Fife. Dismiss me: enough.'"-This first face is of a head, it's fairly normal compared to the others that follow, and it reminds me of maybe the traitor he defeated in a battle early on in the first act.
-4.1.74-81 "[Second Apparition: a Bloody Child] 'Macbeth! Macbeth! Macbeth! Be bloody, bold, and resolute Laugh to scorn the pow'r of man, for none of woman born Shall harm Macbeth'"-This apparition is a baby, and I think it may demonstrate the fact that he doesn't have children, thus no heir to rule. It is also an innocent who is bloody, which also can represent the innocent people Macbeth has killed.
-4.1.87-89 "[Third Apparition: a Child crowned, with a tree in his hand] 'Be lion-mettled, proud, and take no care Who chafes, who frets, or who conspirers are: Macbeth shall never vanquish be until Gret Birnam Wood to high Dunsinane Hill Shall come against him. -This last apparition represents the son of Banquo, and how he shall rule once the forest has reached the hill, which seems unlikely at the time, but will probably come true.
-4.1.64-65 "Pur in sow's blood, that hath eaten her nine farrow..." -Much like the unnatural occurrences that we have seen time and time again, this is the blood of a female pig who killed her babies, and can bee seen as a representation of the unnatural things that Macbeth has done.
4.1.79-81 "Be bloody, bold, and resolute! Laugh to scorn The pow'r of man, for none of woman born shall harm Macbeth." This apparition advises Macbeth to be bloody, to continue to follow the path that he is on and that he will not be killed by a man born of a woman, which is again unnatural, and blood could also somewhat symbolize blood in a sense of "bloodline" or his, or Banquo's offspring.
-4.1.123-124 "FOr the blood-boltered Banquo smiles upon me And points at them for his. What, is this so?" -Banquo's head is matted with blood, and this shows how guilty Macbeth feels, but this bloody person also had a bloodline that will continue for many more generations, which worries Macbeth.
