It illustrates them by fancy, which is a lighter play of imagination, or the feeling of analogy coming short of seriousness, in order that it may laugh with what it loves, and show how it can decorate it with fairy ornament. It modulates what it utters, because in running the whole round of beauty it must needs include beauty of sound; and because, in the height of its enjoyment, it must show the perfection of its triumph, and make difficulty itself become part of its facility and joy. And lastly, Poetry shapes this modulation into uniformity for its outline, and variety for its parts, because it thus realizes the last idea of beauty itself, which includes the charm of diversity within the flowing round of habit and ease. Poetry is imaginative passion. The quickest and subtlest test of the possession of its essence is in expression; the variety of things to be expressed shows the amount of its resources; and the continuity of the song completes the evidence of its strength and greatness. He who has thought, feeling, expression, imagination, action, character, and continuity, all in the largest amount and highest degree, is the greatest poet. Poetry includes whatsoever of painting can be made visible to the mind’s eye, and whatsoever of music can be conveyed by sound and proportion without singing or instrumentation. But it far surpasses those divine arts in suggestiveness, range, and intellectual wealth;--the first, in expression of thought, combination of images, and the triumph over space and time; the second, in all that can be done by speech, apart from the tones and modulations of pure sound. Painting and music, however, include all those portions of the gift of poetry that can be expressed and heightened by the visible and melodious. Painting, in a certain apparent manner, is things themselves; music, in a certain audible manner, is their very emotion and grace. Music and painting are proud to be related to poetry, and poetry loves and is proud of them. Poetry begins where matter of fact or of science ceases to be merely such, and to exhibit a further truth; that is to say, the connexion it has with the world of emotion, and its power to produce imaginative pleasure. Inquiring of a gardener, for instance, what flower it is we see yonder, he answers, ‘a lily’. This is matter of fact. The botanist pronounces it to be of the order of ‘Hexandria Monogynia’. This is matter of science. It is the ‘lady’ of the garden, says Spenser; and here we begin to have a poetical sense of its fairness and grace. It is The plant and flower of _light_, says Ben Jonson; and poetry then shows us the beauty of the flower in all its mystery and splendour.
