Example
In Recompense
by Eda Lou Walton
Now for the long years when I could not love you,
I bring in recompense this gift of yearning-
A luminous vase uplifted to the sun,
Blue with the shadows of near-twilight.
Here in its full round symmetry of darkness,
Burning with swift curved flashes bright as tears,
I lift it to the lonely lips that knew
Its slow creation, and thw wheel of sorrow turning.
Take it with hands like faded petals,
White as the moonlight of our garden;
And for the long years when I could not love you
Drink from its amber-coloured night.\
Some may view this poem about life, a special other or even a remembrance of the past.
Significance
Interpretation is a key in poetry because it can let the readers make a poem something they can relate to and understand in there own way instead of just seeing it in "tunnel-vision".
