 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' 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.
