Richard's power with words is unmatched by any other character in the play. He uses the kinds of highly complicated metaphors and analogies that critics sometimes call "metaphysical conceits." These conceits involve, first, drawing a comparison between an object or person at hand and an apparently unrelated object, and, second, working out the details of the correspondence and adding extra twists. Bloom compares Richard's speeches in this play to the later work of the great seventeenth-century metaphysical poet John Donne.
The play contains many examples of Richard's "metaphysical poetry." Some of the more famous ones include: his frequent comparisons of his kingship to the rising sun, as in the speech he gives when he lands in Wales (III.ii.36-53); his comparison of the human body to a walled castle, which Death may nonetheless conquer with the mere prick of a pin (III.ii.160-170); his comparison of himself and Bolingbroke to two buckets full of water, which rise and fall in opposition, balanced on the fulcrum of the crown (IV.i.182-189); and his comparison of his own body to a clock, which now ticks away the minutes of his sadness (V.v.49-60).
Bloom also suggests that Richard's two roles, as poet and king, "are antithetical, so that his kingship diminishes even as his poetry increases" (249). As Richard loses control over his country and his own destiny, his speeches do become much longer and his ideas and wordplay more complex.
