John Keats was the latest born of the great Romantic poets. Along with Byron and Shelley, he was one of the key figures in the second generation of the movement, despite publishing his work over only a four year period. During his short life, his work was not well received by critics, but his posthumous influence on poets such as Alfred Tennyson and Wilfred Owen was significant. The poetry of Keats was characterised by sensual imagery, most notably in the series of odes which remain among the most popular poems in English literature. The letters of Keats are among the most celebrated by any English poet. ([Source][1].) [1]:http://en.wikipedia.org/wiki/John_Keats
