John Keats, born on October 31, 1795, in London, England, is one of the most revered English Romantic poets. His poetic legacy, though produced in a remarkably short life span—he died at the tender age of 25—is profound. His poetry is characterized by sensual imagery and a profound use of classical mythology, and he is regarded as a master of the sonnet form. Though Keats' early works were not well-received, his later poems such as 'Hyperion,' a Miltonic blank verse epic, have since cemented his place in the literary canon. 'Hyperion' remains a testament to Keats' intricate use of language and his exploration of themes such as the struggle and transcendence of the human spirit. Despite his work receiving mixed criticism during his lifetime, Keats' posthumous influence on poets and the wider literary culture cannot be understated. Unfortunately, his career was cut short by tuberculosis, which claimed his life on February 23, 1821, in Rome. Keats' letters and poems continue to be studied and admired for their emotional depth, mastery of form, and philosophical richness. His contribution to the second generation of Romantic poets remains exemplary, and his works, including 'Ode to a Nightingale,' 'Ode on a Grecian Urn,' and 'To Autumn,' are widely celebrated for their lyrical beauty and insight into the human condition.
