John Keats 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.
Although his poems were not generally well received by critics during his life, his reputation grew after his death, so that by the end of the 19th century he had become one of the most beloved of all English poets. He had a significant influence on a diverse range of poets and writers. Jorge Luis Borges stated that his first encounter with Keats was the most significant literary experience of his life.
The poetry of Keats is characterised by sensual imagery, most notably in the series of odes. Today his poems and letters are some of the most popular and most analysed in English literature.
When Keats died at 25, he had been writing poetry seriously for only about six years, from 1814 until the summer of 1820; and publishing for only four. In his lifetime, sales of Keats's three volumes of poetry probably amounted to only 200 copies. His first poem, the sonnet O Solitude appeared in the Examiner in May 1816, while his collection Lamia, Isabella, The Eve of St. Agnes and other poems was published in July 1820 before his last visit to Rome. The compression of his poetic apprenticeship and maturity into so short a time is just one remarkable aspect of Keats's work.
Although prolific during his short career, and now one of the most studied and admired British poets, his reputation rests on a small body of work, centred on the Odes, and only in the creative outpouring of the last years of his short life was he able to express the inner intensity for which he has been lauded since his death.
