William Shakespeare, Sonnet xlvii
Betwixt mine eye and heart a league is took, 
And each doth good turns now unto the other: 
When that mine eye is famish'd  for a look, 
4
Or heart in love with sighs himself doth smother, 
With my love's picture then my eye doth feast, 
And to the painted banquet bids my heart; 
Another time mine eye is my heart's guest, 
8
And in his thoughts of love doth share a part: 
So, either by thy picture or my love, 
Thyself away art present still with me; 
For thou not farther than my thoughts canst move, 
12
And I am still with them, and they with thee; 
Or if they sleep, thy picture in my sight 
Awakes my heart to heart's and eye's delight.
