THE "aesthetic" poetry is neither a mere reproduction of Greek or medieval poetry, nor only an idealisation of modern life and sentiment. The atmosphere on which its effect depends belongs to no simple form of poetry, no actual form of life. Greek poetry, medieval or modern poetry, projects, above the realities of its time, a world in which the forms of things are transfigured. Of that transfigured world this new poetry takes possession, and sublimates beyond it another still fainter and more spectral, which is literally an artificial or "earthly paradise."
