Why dove?

[just mercedes]

O why dove, why dove, sit alone in your vast fright?
While the blackness swells to swarm on this very night!
Fly dove, fly dove, give the world your shimmering light!
With feathers of white, oh how they glisten so bright!
Please dove, please dove, start before it grips tight!
Pulling us down, with the untold darkest of might!
I cry dove, cry dove, will you not hear my plight?
Your great radiance beside, we could put up a fight!
Rise dove, rise dove, the world you shall incite!
Your illumination beaming, the black will ignite!
Please dove, please dove, smother the darkest blight!
Raise up and take flight, as a gleaming white knight!
So why dove? Why dove? Why sit alone... in vast fright?

The image you play with, of a white dove glowing against the surrounding dark as a symbol of love, peace, hope, joy, is a strong one. I don't think the mono-rhyme helped you at all though, and the very first line strikes a wrong note for me with 'fright'. I think you could rewrite this into a good poem if you first worked out exactly what you want to point out about the contrasts. Thanks for posting this.
