The contents of this little volume may be arranged, not very accurately, in three classes, In the first are certain poems that by their perfection of form show the Greek or classic spirit. Best known of these poems are the fragment "Hyperion," with its Milton-like nobility of style, and "Lamia," which is the story of an enchantress whom love transforms into a beautiful woman, but who quickly vanishes because of her lover's too great curiosity,--a parable, perhaps, of the futility of science and philosophy, as Keats regarded them. Of the poems of the second class, which reflect old medieval legends, "The Pot of Basil," "The Eve of St. Agnes" and "La Belle Dame sans Merci" are praised by poets and critics alike. "St. Agnes," which reflects a vague longing rather than a story, is the best known; but "La Belle Dame" may appeal to some readers as the most moving of Keats's poems. The essence of all old metrical romances is preserved in a few lines, which have an added personal interest from the fact that they may reveal something of the poet's sad love story. In the third class are a few sonnets and miscellaneous poems, all permeated by the sense of beauty, showing in every line the genius of Keats and his exquisite workmanship. The sonnets "On the Sea," "When I have Fears," "On the Grasshopper and Cricket" and "To Sleep"; the fragment beginning "In a drear-nighted December"; the marvelous odes "On a Grecian Urn," "To a Nightingale" and "To Autumn," in which he combines the simplicity of the old classics with the romance and magic of medieval writers,--there are no works in English of a similar kind that make stronger appeal to our ideal of poetry and of verbal melody. Into the three stanzas of "Autumn," for example, Keats has compressed the vague feelings of beauty, of melancholy, of immortal aspiration, which come to sensitive souls in the "season of mists and mellow fruitfulness." It may be compared, or rather contrasted, with another poem on the same subject which voices the despair in the heart of the French poet Verlaine, who hears "the sobbing of the violins of autumn": Les sanglots longs Des violons De l'automne Blessent mon coeur D'une langueur Monotone. KEATS: AN ESSAY OF CRITICISM. Beyond recommending a few of his poems for their beauty, there is really so little to be said of Keats that critics are at their wit's end to express their appreciation. So we read of Keats's "pure aestheticism," his "copious perfection," his "idyllic visualization," his "haunting poignancy of feeling," his "subtle felicities of diction," his "tone color," and more to the same effect. Such criticisms are doubtless well meant, but they are harder to follow than Keats's "Endymion"; and that is no short or easy road of poesy. Perhaps by trying more familiar ways we may better understand Keats, why he appeals so strongly to poets, and why he is so seldom read by other people. [Sidenote: THE SENSE OF BEAUTY]
