The speaker in “Ode to a Grecian Urn” feels that the urn:
D. will outlast him
In this poem, the speaker reflects upon the fact that the urn, as an inanimate object, is timeless. The urn will be unaffected by any decade and century to come. The speaker considers that the urn is permanent and will remain standing still, whilst the transcience of nature will be suffered by all living beings.
