John Keats lived only twenty-five years and four months (1795-1821),yet his poetic achievement is extraordinary.
His writing career lasted a little more than five years (1814-1820),and three of his great odes--"Ode to a Nightingale," "Ode on a Grecian Urn," and "Ode on Melancholy"--were written in one month.Most of his major poems were written between his twenty-third and twenty-fourth years,and all his poems were written by his twenty-fifth year.In this brief period,he produced poems that rank him as one of the great English poets.He also wrote letters which T.S.Eliot calls "the most notable and the most important ever written by any English poet."
