What assurance does the poet give to his friend -give answer with
reference to 'not marble nor gilded monuments'

Nitika Sahdev · Accepted Answer

'Not Marble Nor Gilded Monuments’, one of
Shakespeare’s most famous verses, asserts the immortality of
the poet’s sonnets to withstand the forces of decay over time
While monuments that princes get erected to be remembered forever
will be destroyed, and their creators forgotten, the poet’s
friend will continue to shine brightly in this verse
