John Keats was inspired to write "Ode on a Grecian Urn" after visiting the British Museum and seeing an antique urn. The poem contemplates the images depicted on the urn, which show a scene of figures in a village celebration. Keats explores the paradox that the figures are frozen in time yet seem to tell a story. The analysis discusses how Keats uses paradoxes throughout the poem to reflect on the themes of art, beauty, and the passage of time.
