Who wrote "Ode on a Grecian Urn"?

"Ode on a Grecian Urn" is a quintessential poem written by John Keats, who was a prominent figure of the Romantic movement in English literature. This poem reflects Keats's deep appreciation for beauty and the themes of art and mortality, encapsulating the idea that while life is fleeting, art can capture and preserve moments of beauty forever. Keats uses the Grecian urn as a symbol to explore these profound themes, making it one of his most celebrated works. The poem is noted for its vivid imagery and masterful use of language, attributes deeply associated with Keats's poetic style.

The other choices represent significant literary figures, but none of them authored "Ode on a Grecian Urn." Ezra Pound was known for his role in Modernism, John Milton for his epic poems like "Paradise Lost," and Edgar Allan Poe for his macabre and gothic tales and poems, such as "The Raven." Each has their unique contributions to literature, but this specific work belongs solely to John Keats.
