Sonnet 151 is the 151st of 154 poems in sonnet form by William Shakespeare published in a 1609 collection titled "Shakespeare's sonnets".
 The sonnet belongs to the Dark Lady sequence (sonnets 127–152), which distinguishes itself from The Fair Youth sequence by being more overtly sexual in its passion.
 Sonnet 151 is characterized as "bawdy" and is used to illustrate the difference between the spiritual love for the "Fair Youth" and the sexual love for the "Dark Lady".
 The distinction is commonly made in the introduction to modern editions of the sonnets in order to avoid suggesting that Shakespeare was homosexual.
As the last in the famed collection of sonnets written by English poet and playwright William Shakespeare from 1592 to 1598, Sonnet 154 is most often thought of in a pair with the previous sonnet, number 153.
 As A. L. Rowse states in "Shakespeare's Sonnets: The Problems Solved", Sonnets 153 and 154 "are not unsuitably placed as a kind of coda to the Dark Lady Sonnets, to which they relate."
 Rowse calls attention to the fact that Sonnets 153 and 154 "serve quite well to round off the affair Shakespeare had with Emilia, the woman characterized as the Dark Lady, and the section of the Dark Lady sonnets".
 Shakespeare used Greek mythology to address love and despair in relationships.
 The material in Sonnets 153 and 154 has been shown to relate to the six-line epigram by the Byzantine poet known as Marianus Scholasticus, who published a collection of 3,500 poems called "The Greek Anthology".
 When translated, the epigram resembles Sonnets 153 and 154, addressing love and the story of Cupid, the torch, and the Nymph's attempt to extinguish the torch.
Sonnet 29 is one of 154 sonnets written by the English playwright and poet William Shakespeare.
 It is part of the Fair Youth sequence (which comprises sonnets 1-126 in the accepted numbering stemming from the first edition in 1609).
 In the sonnet, the speaker bemoans his status as an outcast and failure but feels better upon thinking of his beloved.
 Sonnet 29 is written in the typical Shakespearean sonnet form, having 14 lines of iambic pentameter ending in a rhymed couplet.
Alfred Leslie Rowse (4 December 1903 – 3 October 1997), known publicly as A. L. Rowse but to friends and family as "Leslie", was a British author and historian from Cornwall, England, UK.
Sonnet 102 is one of the 154 sonnets written by English playwright and poet William Shakespeare.
 It is one of the Fair Youth sonnets, in which Shakespeare writes of an unnamed youth with whom the poet is enamored.
 Sonnet 102 is among a series of seemingly connected sonnets, from Sonnet 100 to Sonnet 103, in which the poet speaks of a silence between his Muse and himself.
 The exact date of writing is unknown, and there is contention among scholars about when they were written.
 Paul Hammond among other scholars believes that sonnets 61-103 were written primarily during the early 1590s, and then being edited or added to later, during the early 1600s (decade).
 Regardless of date of writing, it was published later along with the rest of the sonnets of the 1609 Quarto.
Sonnet 15 is one of 154 sonnets written by the English playwright and poet William Shakespeare.
 It forms a diptych with Sonnet 16, as Sonnet 16 starts with "But...", and is thus fully part of the procreation sonnets, even though it does not contain an encouragement to procreate.
 The sonnet is within the Fair Youth sequence.
Sonnet 20 is one of the best-known of 154 sonnets written by the English playwright and poet William Shakespeare.
 Part of the Fair Youth sequence (which comprises sonnets 1-126), the subject of the sonnet is widely interpreted as being male, thereby raising questions about the sexuality of its author.
 In this sonnet (as in, for example, Sonnet 53) the beloved's beauty is compared to both a man's and a woman's.
Sonnet 72 is one of 154 sonnets written by the English playwright and poet William Shakespeare.
 It is a member of the Fair Youth Sequence, in which The Poet expresses his love toward a young man.
 The Fair Youth Sequence includes Sonnet 1 through Sonnet 126.
 Sonnet 72 prominently features a dark, morbid tone with references to death and the afterlife.
Sonnet 6 is one of 154 sonnets written by the English playwright and poet William Shakespeare.
 It is a procreation sonnet within the Fair Youth sequence.
 The sonnet continues Sonnet 5, thus forming a diptych.
 It also contains the same distillatory trope featured in Sonnet 54, Sonnet 74 and Sonnet 119.
Sonnet 110 is one of 154 sonnets written by the English playwright and poet William Shakespeare.
 Sonnet 110 was published along with the other sonnets in the 1609 Quarto.
 The sonnet falls in place with the Fair Youth sequence of Shakespeare's sonnets, in which the poet expresses his love towards a young man.
 The mystery of the young man is still unknown today.
 However, there are many different theories by various scholars of who this young man may be.
 There has been much debate whether or not this sonnet was written about Shakespeare's disdain with the stage and actors.
 Whereas others have interpreted sonnet 110 as the poet confessing his love to a young man.
