Sonnet 145 is unusual in that, unlike any of Shakespeare's other sonnets, it is written in tetrameters. Some believe that Shakespeare is not the true author of this poem because of its anomalous rhythm, and for more serious reasons. In his comprehensive edition of the play, Raymond MacDonald Alden has compiled a selection of criticism from noted scholars. Dowden calls the sonnet "ill-managed"; Wyndham says it has "an unpleasing assonance between the rhyme-sounds of the first quatrain"; and Acheson concludes that Shakespeare "certainly did not write [this sonnet], nor did anyone to whom the title of poet might be applied: it is possibly a flight of Southampton's own muse" (351).
