William Shakespeare, Sonnet cxxvii
In the old age black was not counted fair, 
Or if it were, it bore not beauty's name; 
But now is black beauty's successive heir, 
4
And beauty slander'd  with a bastard shame: 
For since each hand hath put on nature's power, 
Fairing the foul with art's false borrow'd  face, 
Sweet beauty hath no name, no holy hour, 
8
But is profan'd , if not lives in disgrace. 
Therefore my mistress' eyes are raven black, 
Her eyes so suited; and they mourners seem 
At such, who, not born fair, no beauty lack, 
12
Slandering creation with a false esteem: 
Yet so they mourn, becoming of their woe, 
That every tongue says, beauty should look so.
