The happiest instance I remember of imaginative metaphor, is Shakespeare’s moonlight ‘sleeping’ on a bank; but half his poetry may be said to be made up of it, metaphor indeed being the common coin of discourse. Of imaginary creatures, none out of the pale of mythology and the East are equal, perhaps, in point of invention, to Shakespeare’s Ariel and Caliban; though poetry may grudge to prose the discovery of a Winged Woman, especially such as she has been described by her inventor in the story of _Peter Wilkins_; and in point of treatment, the Mammon and Jealousy of Spenser, some of the monsters in Dante, particularly his Nimrod, his interchangements of creatures into one another, and (if I am not presumptuous in anticipating what I think will be the verdict of posterity) the Witch in Coleridge’s _Christabel_, may rank even with the creations of Shakespeare. It may be doubted, indeed, whether Shakespeare had bile and nightmare enough in him to have thought of such detestable horrors as those of the interchanging adversaries (now serpent, now man), or even of the huge, half-blockish enormity of Nimrod,--in Scripture, the ‘mighty hunter’ and builder of the tower of Babel,--in Dante, a tower of a man in his own person, standing with some of his brother giants up to the middle in a pit in hell, blowing a horn to which a thunderclap is a whisper, and hallooing after Dante and his guide in the jargon of a lost tongue! The transformations are too odious to quote: but of the towering giant we cannot refuse ourselves the ‘fearful joy’ of a specimen. It was twilight, Dante tells us, and he and his guide Virgil were silently pacing through one of the dreariest regions of hell, when the sound of a tremendous horn made him turn all his attention to the spot from which it came. He there discovered through the dusk, what seemed to be the towers of a city. Those are no towers, said his guide; they are giants, standing up to the middle in one of these circular pits.
