Disguise is major theme in Macbeth. Throughout the story several characters disguise their personalities or adapt in order to protect themselves, just as chameleon changes colour to adapt to it's environment.
" A falcon tow'ring in her prode of place, was a mousing owl hawk'd at and kill'd... And Duncan's horses... Turn'd wild in nature, broke their stalls flung of contending with contending obedience." ( Act 2, Scene 4) This quote is describing the strange occurances on the night of Duncan's death. It's not normal for a owl to kill a falcon and for horses to become that uncontrollable. The strange animal behaviours are suggesting that fowl play was the cause of Duncan's untimely death.
The lion jumping represents Macbeth taking leaps of faith. For example, killing Duncan, planning Banquos murder and doing other things that, the lion in the back who is supposed to be Lady Macbeth is just in the blur and is slowly witnessing her husband do these terrible deeds.
This rose represents Lady Macbeth and how she seems to be a beautiful rose when really she has a lot of thorns. Lady Macbeth appears to be this beautiful young women when really she has a lot of imperfections like pushing Macbeth to kill Duncan and to do dirty work for her. (hence the term "every rose has its thorns".)
"What man may dare, I dare: Approach thou like the rugged Russian bear, the arm'd rhinoceros, or the hyrcan tiger; take any shape but that, and my firm nerves shall never tremble or be alive again,..." ( Act 3, Scene 4) Macbeth is discussing the ghost of Banquo with Lady Macbeth. Macbeth is saying that he wouldn't even fear these ferocious animals if they came near him. This quote suggests that Macbeth may be regretting the murder of Banquo and that he isn't as fearless as he seems.
" Throw physic to the dogs, I'll none of it." ( Act 5, Scene 3) At this point Macbeth has just been told that the doctor can't help Lady Macbeth because her illness isn't medical but rather mental. Shakespeare used this imagery to evoke Macbeth's frustration over Lady Macbeth's condition.
" I come, Graymalkin, Paddock calls; -- anon" (Act 1, Scene 1) A graymalkin is another term for cat and a paddock is another term for toad. These are both described as the witches demon companions or familiar spirits. In this case Shakespeare used the cat because cat's have always been symbol of witches and their mysterious or sneaky ways. The toad represents not only the witches outer appearance but their inner appearance as well.
"... As sparrows, eagles, or hare, the lion." ( Act 1, Scene 2) The soldier is comparing macbeth and Banquo to animals. Macbeth and Banquo defeat their foes just as easily as an eagle can kill a sparrow or a lion can kill a hare.
" Look like the innocent flower but be the serpent under't." ( Act 1, Scene 5) In this quote Lady Macbeth is telling Macbeth to act innocent and trusting but in actuality be venomous, deceitful and sneaky. Basically, pretend to be a friend when you're actually a foe.
Trust is a major theme in Macbeth because their are many times trust is broken and gained throughout the play. Macbeth loses trust in many people in the play one for whom is Duncan. Macbeth killed Duncan even though he trusted Macbeth and worshiped him for the things he had done on the battlefield. This egg represents the characters trust and how when the trust is broken their becomes cracks in the relationships and it is impossible to recover.
" The most diminutive birds, will fight, Her young ones in the nest against the owl." ( Act 4, Scene 2) Lady Macduff is saying even the smallest and weakest birds fight any predator in order to protect their children. This foreshadows the murder of her and children.
" They have tied me to a stake; I cannot fly, but bear-like I must fight the course." ( Act 5, Scene 7) This animal imagery was used as a metaphor for bear baiting. Macbeth realizes that like a bear he is trapped, but he thinks that if he keeps fighting to the end of his 'course' things may work out in his favour.
" What, all my pretty chickens and their dam at one fell swoop?" ( Act 4, Scene 3) This quote occurred right after macduff heard the news of his family's murder. Shakespeare chose to use chickens because they are vulnerable and helpless. This makes the audience sympathize for Macduff's loss now knowing just how little of a chance his family had for survival.
