Be not her maid, since she is envious;\n\

And none but fools do wear it; cast it off.\n\
It is my lady, O, it is my love!\n\
O, that she knew she were!\n\
She speaks yet she says nothing: what of that?\n\
Her eye discourses; I will answer it.\n\
I am too bold, 'tis not to me she speaks:\n\
Two of the fairest stars in all the heaven,\n\
Having some business, do entreat her eyes\n\
To twinkle in their spheres till they return.\n\
What if her eyes were there, they in her head?\n\
The brightness of her cheek would shame those stars,\n\
As daylight doth a lamp; her eyes in heaven\n\
Would through the airy region stream so bright\n\
That birds would sing and think it were not night.\n\
See, how she leans her cheek upon her hand!\n\
O, that I were a glove upon that hand,\n\

O, speak again, bright angel! for thou art\n\
As glorious to this night, being o'er my head\n\
As is a winged messenger of heaven\n\
Unto the white-upturned wondering eyes\n\
Of mortals that fall back to gaze on him\n\
