" [I. ii. 42] Again , blood is found haunting Macbeth in act two , scene one of the play , in which a visionary dagger is stained with "gouts of blood." In the same act and scene , after the murder Duncan , Macbeth cries declares that nothing , even "great Neptune"s oceans" , will be able to cleanse the blood that stains his hand :.

             "Will all great Neptune"s ocean wash this blood clean from .

             my hand? No , this my hand will rather the multitudinous .

             seas incarnadine , making the green one red." [II. ii. 58-60].

             Next , the image of blood is induced when Macbeth calls upon the "bloody and invisible hand" of night to help the murderers he has hired carry out their assassination of Banquo and his son , Fleance. Then , Macbeth realizes that "blood will have blood" and that his murderous plots will all come to and end with his death. Finally , at the end of the banquet scene , Macbeth confesses that he is "in blood , stepp"d in so far that , should [he] wade no more , returning [would be] as tedious as to go o"er." [III. iv. 136-7] Through all these instances of blood symbolism and imagery , it is obvious that "Macbeth is about blood." (Muir , Pg. 271 ).

             Yet another form of symbolism used in the play is that of unnaturalness. Throughout the work , it is used in the constant referral to Macbeth"s crime of murder and emphasizes the fact it is not natural and , in turn , is a "convulsion of nature." (Spurgeon , Pg. 20) Although powerful , the idea of unnaturalness occurs mostly in one part of the play , immediately before and after the murder of Duncan. Macbeth , obviously bothered by the act that he had just committed , states .

             how Duncan"s wounds "look"d like a breach in nature for ruin"s wasteful entrance." [II. iii. 118] Then , Macbeth continues on by saying that he had "murdered sleep" , another unnatural occurrence,.
