While William Shakespeare's Sonnet 130 does take a satirical turn in its treatment of the Petrarchan form as well as the traditional Petrarchan sonnet's subject matter of comparison of a lover to natural phenomena, in theme, it is not satirical. For, while the lover's eyes are not like the sun, her hair is like "black wires," and her breath is anything like perfume, he yet loves her:
I love to hear her speak,--yet well I know
That music hath a far more pleasing sound....
Further, the speaker declares, though she merely "walks, treads on the ground,"
And, yet, by heaven, I think my love as rare
As any she belied with false compare.
The couplet, then, dismisses all the conventional comparisons that the speaker has so satirized, explicating the point--theme--of all these contrasts: his comparisons of his lover, albeit unfavorable, is as rare for him as those beauties whom the Petrarchan sonnets laud. For, the speaker loves his mistress just as much as the others love their beauties because beauty is subjective.
