John Keats, one of the principal poets in the English Romantic movement, was born on October 31, 1795, in London, England. Despite his tragically short lifespan, Keats has become one of the enduring figures of British Romantic literature with his sensual imagery, intense lyrical expression, and thoughtful engagement with themes of beauty, love, and mortality. Keats' literary oeuvre may not be vast, owing to his untimely death from tuberculosis at the age of 25 on February 23, 1821, but it is profoundly influential. Keats' major works include 'Ode to a Nightingale', 'Ode on a Grecian Urn', 'Ode to Psyche', 'To Autumn' and the epic poem 'Hyperion'. These poems are known for their vivid imagery, emotional depth, and philosophical musings on the transient nature of life and the enduring power of art. The 'Letters of John Keats to His Family and Friends', edited by Sidney Colvin and published posthumously, offer remarkable insight into his poetic philosophy and his personal struggles. Keats' letters are lauded for their eloquence, rich reflective content, and are often considered as significant to literary studies as his poetry. Through his work, Keats continues to be admired for his evocative language and rich aesthetic sensibility which left an indelible mark on the literary world.
