Answer: The poet is saying that people don't live long; life is brief.
Step-by-step explanation:
''Ode on a Grecian Urn" was written by the English Romantic poet, John Keats. It is one of the several ''Great Odes of 1819" which was first published anonymously.
In this poem, Keats compares the duration of a vessel with that of our life. The vessel is resistant and will last for a long period of time, while our life is brief and fragile, and leads to the old age. The Grecian urn, passed down from generation to generation, does not age and does not die. With this unusual comparison, the poet portrays our limited existence on earth. This theme is reflected in the phrase "old age shall this generation waste.''
