Question

I "Not Marble, nor the Gilded Monuments", how does the poet justify that
his verse will live on forever
​

Answer 1

He said that neither Mars nor his sword can destroy his poem which he had written in praise of his friend. Mars can destroy each and everything but he had no potential to destroy his poem. The monuments of past will become the history but the poem will not lose it's beauty.
