John Keats was born in October 1795. His Poems appeared in 1817, while Endymion was published in 1818, both to mixed reviews. In 1819 he wrote The Eve of St Agnes, La Belle Dame sans Merci, the major odes, Lamia and the Fall of Hyperion. Keats was already unwell when preparing his 1820 volume for the press; by the time it appeared in July he was desperately ill. He died in Rome in 1821, in a rented apartment next to the Spanish Steps, at the age of twenty-five. John Barnard is Emeritus Professor of English Literature at the University of Leeds and has edited The Complete Poems of Keats for Penguin Classics.
