This poem is not anything like the Sun

My Mistress' Eyes are Nothing Like the Sun (Sonnets CXXX)

My mistress' eyes are nothing like the sun;
Coral is far more red than her lips' red:
If snow be white, why then her breasts are dun;
If hairs be wires, black wires grow on her head.
I have seen roses damask'd, red and white,
But no such roses see I in her cheeks;
And in some perfumes is there more delight
Than in the breath that from my mistress reeks.
I love to hear her speak, yet well I know
That music hath a far more pleasing sound.
I grant I never saw a goddess go:
My mistress, when she walks, treads on the ground.
And yet, by heaven, I think my love as rare
As any she belied with false compare.

William Shakespeare

I like this poem.  We start off with Shakespeare saying he has this love of his, and then starts to bash her.  Her eyes are dull, hair is stringy, breath stinks, skin is colorless she is not the beauty you may think.  He goes against what people might expect from a standard love poem.  Perhaps he is mocking love poems all together.  Regardless we know he loves her.  She is his mistress, and he loves to listen to her and be with her.  He says he never saw a goddess before and maybe he is saying that in love poems all the women seem to be a goddess.  Indeed all the comparisons he makes are real.  He knows what music sounds like he has seen roses but not a goddess.  The last line could be another jab at romantic poetry all together, but it could also mean that his mistress has traits to love outside of the poem.
