Banquo's taking-off with the encouragement--'Then be thou jocund: ere the bat has flown his cloistered flight; ere to black Hecate's summons the shard-born beetle has rung night's yawning peal, there shall be done--a deed of dreadful note.' In Lady Macbeth's speech, 'Had he not resembled my father as he slept, I had done't,' there is murder and filial piety together, and in urging him to fulfil his vengeance against the defenceless king, her thoughts spare the blood neither of infants nor old age. The description of the Witches is full of the same contradictory principle; they 'rejoice when good kings bleed'; they are neither of the earth nor the air, but both; 'they should be women, but their beards forbid it'; they take all the pains possible to lead Macbeth on to the height of his ambition, only to betray him in deeper consequence, and after showing him all the pomp of their art, discover their malignant delight in his disappointed hopes, by that bitter taunt, 'Why stands Macbeth thus amazedly?' We might multiply such instances everywhere. The leading features in the character of Macbeth are striking enough, and they form what may be thought at first only a bold, rude, Gothic outline. By comparing it with other characters of the same author we shall perceive the absolute truth and identity which is observed in the midst of the giddy whirl and rapid career of events. Macbeth in Shakespeare no more loses his identity of character in the fluctuations of fortune or the storm of passion, than Macbeth in himself would have lost the identity of his person. Thus he is as distinct a being from Richard III as it is possible to imagine, though these two characters in common hands, and indeed in the hands of any other poet, would have been a repetition of the same general idea, more or less exaggerated. For both are tyrants, usurpers, murderers, both aspiring and ambitious, both courageous, cruel, treacherous. But Richard is cruel from nature and constitution. Macbeth becomes so from accidental circumstances. Richard is from his birth deformed in body and mind, and naturally incapable of good. Macbeth is full of 'the milk of human kindness, is frank, sociable, generous. He is tempted to the commission of guilt by golden opportunities, by the instigations of his wife, and by prophetic warnings. Fate and metaphysical aid conspire against his virtue and his loyalty. Richard, on the contrary, needs no prompter, but wades through a series of crimes to the height of his ambition from the ungovernable violence of his temper and a reckless love of mischief. He is never gay but in the prospect or in the success of his villanies; Macbeth is full of horror at the thoughts of the murder of Duncan, which he is with difficulty prevailed on to commit, and of remorse after its perpetration. Richard has no mixture of common humanity in his composition, no regard to kindred or posterity, he owns no fellowship with others, he is 'himself alone'.
