This authoritative edition was originally published in the acclaimed Oxford Authors series under the general editorship of Frank Kermode. It brings together a unique combination of Keats's poetry and prose - all the major poems, complemented by a generous selection of Keats's letters - togive the essence of his work and thinking. In his tragically short life Keats wrote an astonishing number of superb poems; his stature as one of the foremost poets of the Romantic movement remains unassailable. This volume contains all the poetry published during his lifetime, including Endymion in its entirety, the Odes, 'Lamia', and bothversions of 'Hyperion'. The poetry is presented in chronological sequence, illustrating the staggering speed with which Keats's work matured. Further insight into his creative process is given by reproducing, in their original form, a number of poems that were published posthumously. Keats's letters are admired almost as much as his poetry and were described by T. S. Eliot as 'certainly the most notable and most important ever written by any English poet'. They provide the best biographical detail available and shed invaluable light on Keats's poems.
