John Keats (31 October 1795 - 23 February 1821) was an English Romantic poet. He was one of the main figures of the second generation of romantic poets along with Lord Byron and Percy Bysshe Shelley, despite his work only having been in publication for four years before his death. The poetry of Keats is characterized by sensual imagery, most notably in the series of odes. Today his poems and letters are some of the most popular and most analyzed in English literature.
