Though little known in his own lifetime, John Keats' s (1795-1821) hope that he might be considered among the English poets after his death has come to pass, and he is now considered one of the foremost poets of English literature. Keats died of consumption in Rome, with financial worries and the loss of many of those he loved most having plagued his short life.
No one else in English poetry, save Shakespeare, has in expression quite the fascinating felicity of Keats, his perfection of loveliness. -- Matthew Arnold
