Classic Poem

Who art thou, fair one, who usurp'st the place
Of Blanch, the lady of the matchless grace?
Come, fair and pretty, tell to me,
Who, in thy life-time, thou might'st be.
Thou pretty art and fair,
But with the lay Blanch thou never must compare.
No need for Blanch her history to tell;
Whoever saw her face, they there did read it well.
But when I look on thee, I only know
There lived a preatty maid some hundred years ago.
