Analysis of The Grave of Love

I DUG, beneath the cypress shade,
   What well might seem an elfin's grave;
And every pledge in earth I laid,
   That erst thy false affection gave.

I press'd them down the sod beneath;
   I placed one mossy stone above;
And twined the rose's fading wreath
   Around the sepulchre of love.

Frail as thy love, the flowers were dead
   Ere yet the evening sun was set:
But years shall see the cypress spread,
   Immutable as my regret.
