Act 3 Scene 1 Of Macbeth's Soliloquy '

Analysis:
In this soliloquy, Macbeth mentions how becoming the king is pointless if he cannot pass down the crown to his son (Shakespeare, Act 3, Scene 1, 65-67). The weird witches foretold that Macbeth would become King, which he now believes, but they also told them how Banquo descendents will become Kings as well. This stirs anger in his heart because he killed Duncan to become king, and if his descendents will not become kings there is no reason to take the helm (Shakespeare, Act 3, Scene 1, 68). Now Macbeth feels horrible, and his animosity towards Banquo worsens. Macbeth mentions how this, “put rancours in the vessel of my peace”, and immediate distress on the killing of his dear friend Duncan for the future descendents of Banquo (Shakespeare,

“. . . and mine eternal jewel/Given to the common enemy of man” – (Shakespeare, Act 3, Scene 1, 72-73)
Macbeth is mentioning how his importance of his inner being as a person, and how it was given to the common enemy of man. I feel like this is a biblical reference, how the eternal jewel within us is the Holy Spirit, and the common enemy of man is evil, which represents the devil.
Metaphor
“. . . Upon my head they placed a fruitless crown.” – (Shakespeare, Act 3, Scene 1, 65)
Macbeth is mentioning how his crown is “fruitless”, which means no one can retrieve the crown from his family, so he finds it worthless. The crown could not be given to the fruits of his family, his future sons/descendents; therefore it is a “fruitless crown”. (Fruitless =

. . And put a barren sceptre in my gripe,” – (Shakespeare, Act 3, Scene 1, 66)
By reading carefully in the context, this was metaphorically stating that the descendents of Macbeth will have no power, and will be in a lower class. (Barren Sceptre = Poorness)
Foreshadowing
“. . . Rather than so, come fate into the list, and champion me th’ utterance. . .” - (Shakespeare, Act 3, Scene 1, 75)
This reveals that Macbeth is envious of Banquo, therefore he will kill him to truly deserve what he desires.
Symbolism
“ . . . Upon my head they placed a fruitless crown” – (Shakespeare, Act 3, Scene 1, 65)
The crown symbolizes high standing, but in this context, Macbeth states the crown as “fruitless” which means he finds hiss crown insignificant to him because Banquo’s descendents will become Kings.
“. . . And put a barren sceptre in my gripe,” – (Shakespeare, Act 3, Scene 1, 66)
The barren sceptre represents two things, “barren” represents poorness, and “sceptre” represents richness because it can only be held by Kings. The barren sceptre represents poorness because Macbeth will be the only person in his family line who was the king, therefore his future family members will not become
