In the final couplet, the speaker proclaims his love for his mistress by declaring that he makes no false comparisons, the implication being that other poets do precisely that.

Shakespeare's sonnet aims to do the opposite, by indicating that his mistress is the ideal object of his affections because of her genuine qualities, and that she is more worthy of his love than the paramours of other poets who are more fanciful.

It follows the typical rhyme scheme of the form ABAB CDCD EFEF GG and is composed in iambic pentameter, a type of poetic metre based on five pairs of metrically weak/strong syllabic positions.

[6] However, E. G. Rogers points out the similarities between Watson's "Passionate Century of Love," Sonnet 130, and Richard Linche's poem collection entitled "Diella.

This, along with other similarities in textual content, leads, as E. G. Rogers points out, the critic to believe that Diella may have been the source of inspiration for both homage, by Watson's "Passionate Century of Love," and satire by Shakespeare's "Sonnet 130."

The idea of satire is further enforced by the final couplet of "130" in which the speaker delivers his most expositional line: "And yet, by heaven, I think my love as rare, as any she belied with false compare."

Flesch notes that while what Shakespeare writes of can seem derisive, he is in reality complimenting qualities the mistress truly exhibits, and he ends the poem with his confession of love.

Helen Vendler, who is also referenced in Steele's article states that the final couplet would read; "In all, by heaven, I think my love as rare/ As any she conceived for compare."

All three, Steele, Booth, and Vendler, believe that in this couplet, Shakespeare is responding to Petrarchan imagery because other sonneteers actively misrepresent, or "belie" their mistress' beauty.
