"Then in the blazon of sweet beauty's best, of hand, of foot, of lip, of eye, of brow, I see their antique pen would have expressed ev'n such beauty as you master now." (Shakespeare,
5-8). In these lines, Shakespeare mentions that whenever he read a poem cataloging a women's beauty talking about similar characteristics mentioned in the passage below, he noticed those poems were written with the same description of the beauty he was seeing in the person he was dedicating this poem to.
"So all their praises are but prophecies of this our time, all you prefiguring, and for they looked but with divining eyes, they had no skill enough your worth to sing." (9-12). From these lines, it is shown Shakespeare's opinion towards the gift of the poet. When talking about the meaning of his words, he was commenting that because of this gift of prophecy the poets possessed, they wouldn't be able to find a fitting way to describe her beauty. As he says at the
end of the quote below "And for they looked but with divining eyes, they had not skill enough your worth to sing."(11-12) he also uses the word 'sing' as way to say ''worth.'' In this case, he is talking about the woman's beauty.
"For we, which now behold these present days, have eyes to wonder, but lack tongues to praise."(13-14) In this last two lines of the sonnet, Shakespeare reveals his purpose with this sonnet. He means that the ones that are able to see her beauty will be amazed by it, but they will lack the poetic skill to describe it. They will find no words to describe her amazing beauty.
In response to this sonnet, the message Shakespeare wants to transmit to the reader is that the lover he is dedicating the sonnet to is a beautiful woman with incomparable beauty.
