127. The dark woman of the following sonnets is as much a mystery as ever, despite the many pages that editors, critics, and playwrights have devoted to her. Some scholars and dramatists assume her to be a maid of honor of Queen Elizabeth, Mary Fitton, at one time the mistress of William Herbert, Earl of Pembroke.

135. In this and in the following sonnet, Shakespeare writes a series of puns on the word 'will,' using it as a proper name, as 'wish,' and as 'lust.' Used as a proper name, 'Will in over-plus; More than enough am I' (ll. 2, 3), refers to Shakespeare; 'Will to boot,' (l. 2) refers to another man, possibly to the friend of sonnet 133, l. 2.
