Do not all charms fly at the mere touch of cold philosophy? There was an awful rainbow once in heaven: we know her woof, her texture; she is given in the dull catalogue of common things. Philosophy will clip an angel's wings, conquer all mysteries by rule and line, empty the haunted air, and gnome mine unweave a rainbow.
John Keats (October 31, 1795 February 23, 1821) was one of the principal poets in the English Romantic movement. During his short life, his work was the subject of constant critical attacks, and it was not until much later that the significance of the cultural change which his work both presaged and helped to form was fully appreciated. Keats's poetry is characterized by an exuberant love of the language and a rich, sensuous imagination; he often felt that he was working in the shadow of past poets, and only towards the end of his life was he able to produce his most original and most memorable poems.
