For since 'twas mine, the white hath lost its hue,
To show 'twas ne'er it self but whilst in you,
The virgin wax hath blushed it self to red
Since it with me hath lost its maidenhead.
You, fairest nymph, are wax: O, may you be
As well in softness as in purity!
Till fate and your own happy choice reveal
Whom you shall so far bless to make your seal.

John Dryden
