and so on; in short, that he despises the 'modern morals' which distinctly approve of monogamy? Human love, one would say, becomes a fitting type of a loftier emotion, in so far as it implies exclusive devotion to its object. During this uncomfortable intrusion of a discordant theory, we seem to be listening less to the passionate utterance of a true poet than to the shrill tones of a conceited propagator of flimsy crotchets, proclaiming his tenets without regard to truth or propriety. Mrs. Shelley does not seem to have entered into the spirit of the composition; and we can hardly wonder if she found this little bit of argument rather a stumbling-block to her comprehension. To return, however, from these moral deductions to the more general principles. It is scarcely necessary to insist at length upon the peculiar idealism implied in Shelley's poetry. It is, of course, the first characteristic upon which every critic must fasten. The materials with which he works are impalpable abstractions where other poets use concrete images. His poetry is like the subtle veil woven by the witch of Atlas from 'threads of fleecy mists,' 'long lines of light,' such as are kindled by the dawn and 'star-beams.' When he speaks of natural scenery the solid earth seems to be dissolved, and we are in presence of nothing but the shifting phantasmagoria of cloudland, the glow of moonlight on eternal snow, or the 'golden lightning of the setting sun.' The only earthly scenery which recalls Shelley to a more material mind is that which one sees from a high peak at sunrise, when the rising vapours tinged with prismatic colours shut out all signs of human life, and we are alone with the sky and the shadowy billows of the sea of mountains. Only in such vague regions can Shelley find fitting symbolism for those faint emotions suggested by the most abstract speculations, from which he alone is able to extract an unearthly music. To insist upon this would be waste of time. Nobody, one may say briefly, has ever expanded into an astonishing variety of interpretation the familiar text of Shakespeare— We are such stuff As dreams are made on, and our little lives Are rounded with a sleep. The doctrine is expressed in a passage in 'Hellas,' where Ahasuerus states this as the final result of European thought. The passage, like so many in Shelley, shows that he had Shakespeare in his mind without exactly copying him. The Shakespearean reference to the 'cloud-capped towers' and 'gorgeous palaces' is echoed in the verses which conclude with the words:—
