William Shakespeare: Since I left you, mine eye is in my mind

Since I left you, mine eye is in my mind

Since I left you, mine eye is in my mind; And that which governs me to go about Doth part his function and is partly blind, Seems seeing, but effectually is out; For it no form delivers to the heart Of bird, of flower, or shape which it doth latch: Of his quick objects hath the mind no part,  Nor his own vision holds what it doth catch; For if it see the rud'st or gentlest sight, The most sweet favour or deformed'st creature, The mountain or the sea, the day or night: The crow, or dove, it shapes them to your feature.   Incapable of more, replete with you,   My most true mind thus maketh mine untrue.
