A famous line from Romeo and Juliet, when Romeo first sees Juliet across a crowded room...
[To a Servingman] What lady is that, which doth enrich the hand
Of yonder knight?
I know not, sir.
O, she doth teach the torches to burn bright!
It seems she hangs upon the cheek of night
Like a rich jewel in an Ethiope's ear;
Beauty too rich for use, for earth too dear!
Act I, Scene 5
