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.
A crown of sonnets or sonnet corona is a sequence of sonnets, usually addressed to one person, and/or concerned with a single theme.
 Each of the sonnets explores one aspect of the theme, and is linked to the preceding and succeeding sonnets by repeating the final line of the preceding sonnet as its first line.
 The first line of the first sonnet is repeated as the final line of the final sonnet, thereby bringing the sequence to a close.
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 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 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.
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.
Pamphilia to Amphilanthus is a sonnet sequence by the English Renaissance poet Lady Mary Wroth, first published as part of "The Countess of Montgomery's Urania" in 1621, but subsequently published separately.
 It is the second known sonnet sequence by a woman writer in England (the first was by Anne Locke).
 The poems are strongly influenced by the sonnet sequence "Astrophel and Stella" (1580) penned by her uncle Sir Philip Sidney.
 Like Sidney's sequence, Wroth's sonnets passed among her friends and acquaintances in manuscript form before they were published in 1621.
 In Wroth's sequence, she upends Petrarchan tropes by making the unattainable object of love male.
Heaven's Gate, a phrase made familiar from William Shakespeare's Sonnet 29, beginning "When in disgrace with fortune and men's eyes", may refer to:
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.
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.
