His figure stands before us as his contemporaries have drawn it: small and wiry, the right shoulder higher than the left, wearing his rich brown hair long in order to conceal this malformation, biting his under-lip, always restless, always with his hand on his dagger-hilt, sliding it up and down in its sheath, without entirely drawing it. Shakespeare has succeeded in throwing a halo of poetry around this tiger in human shape. The figures of the two boy princes, Edward's sons, stand in the strongest contrast to Richard. The eldest child already shows greatness of soul, a kingly spirit, with a deep feeling for the import of historic achievement. The fact that Julius Cæsar built the Tower, he says, even were it not registered, ought to live from age to age. He is full of the thought that while Cæsar's "valour did enrich his wit," yet it was his wit "that made his valour live," and he exclaims with enthusiasm, "Death makes no conquest of this conqueror." The younger brother is childishly witty, imaginative, full of boyish mockery for his uncle's grimness, and eager to play with his dagger and sword. In a very few touches Shakespeare has endowed these young brothers with the most exquisite grace. The murderers "weep like to children in their death's sad story":-- "Their lips were four red roses on a stalk, And, in their summer beauty, kiss'd each other." Finally, the whole tragedy of Richard's life and death is enveloped, as it were, in the mourning of women, permeated with their lamentations. In its internal structure, it bears no slight resemblance to a Greek tragedy, being indeed the concluding portion of a tetralogy. Nowhere else does Shakespeare approach so nearly to the classicism on the model of Seneca which had found some adherents in England. The whole tragedy springs from the curse which York, in the Third Part of _Henry VI_. (i. 4), hurls at Margaret of Anjou. She has insulted her captive enemy, and given him in mockery a napkin soaked in the blood of his son, the young Rutland, stabbed to the heart by Clifford. Therefore she loses her crown and her son, the Prince of Wales. Her lover, Suffolk, she has already lost. Nothing remains to attach her to life. But now it is her turn to be revenged. The poet has sought to incarnate in her the antique Nemesis, has given her supernatural proportions and set her free from the conditions of real life. Though exiled, she has returned unquestioned to England, haunts the palace of Edward IV., and gives free vent to her rage and hatred in his presence and that of his kinsfolk and his courtiers. So, too, she wanders around under Richard's rule, simply and solely to curse her enemies--and even Richard himself is seized with a superstitious shudder at these anathemas.
