Why is Shakespeare's Sonnet 18 so famous?
Shakespeare's Sonnet 18 is so famous, in part, because it addresses a very human fear: that someday we will die and likely be forgotten. The speaker of the poem insists that the beauty of his beloved will never truly die because he has immortalized her in text. He has declared her to be more beautiful than one of the most beautiful things, a summer day. But she will be constant, eternal, and it cannot be.
