Analysis of Beauty

Even as on some black background full of night
And hollow storm in cloudy disarray,
The forceful brush of some great master may
More brilliantly evoke a higher light;
So beautiful, so delicately white,
So like a very metaphor of May,
Your loveliness on my life's sombre grey
In its perfection stands out doubly bright.

And yet your beauty breeds a strange despair,
And pang of yearning in the helpless heart;
To shield you from time's fraying wear and tear,
That from yourself yourself would wrench apart,
How save you, fairest, but to set you where
Mortality kills death in deathless art?
