Analysis of Upon The Sand

One day I wrote her name upon the sand
But came the waves and washed it all away.
Again, I wrote it with a defter hand
But came the tide and made my script its prey.

You're vain, she said, that you in vain attempt
Immortalizing mortal thing as I.
Like sand-script, from decay I'm not exempt
So then my name be likewise wiped out dry.

Not right thought I; let lesser things devise
To yield to dust but she shall live in fame.
With rhyme, her merits I will eternalize
And to the heavens raise her splendid name.

Where, though demise shall all the world subdue,
Our love won't die and after life renew.
