Sonnet 47 by Shakespeare

Shakespeare's Sonnet 47 is one of the large number of the sequence addressed to a well-born young man. More locally, it is a thematic continuation of "Sonnet 46."

Paraphrase
My heart and my eyes have reached a mutually beneficial understanding. When my eye yearns for the sight of my beloved, or when my heart is pining, then my eye shares the sight of my beloved (seen in a painting) with my heart. At other times, my heart will share with my eye (in imagination) some memory or thought of the beloved. So whether in painting or in imagination, you are always present with me. It is impossible for you to move outside the sphere of my thoughts; I am always with my thoughts, and they are always with you. Or, if my thoughts are, as it were, sleeping, then your painting will delight my eyes and thus awake my heart.

Source and analysis
The sonnet thematically continues from the "verdict" delivered by the eye and heart in the previous sonnet. Kerrigan perceives an allusion to the story of Zeuxis and Parrhasius in the "painted banquet" of line 8. Comparing the same image to similar passages The Fairy Queen, Booth regards the image as symbolic of coldness and insufficience. Sidney Lee suggests that the conceit of the poem inspired a passage in John Suckling's Tragedy of Benneralt. Edmond Malone notes that the figure of line 3 appears also in The Comedy of Errors; Edward Dowden notes parallels to Sonnet 75.
