Origins and Development of the Sonnet
The sonnet is a 14-line poetic form that originated in Italy and traveled to England during the Renaissance. Understanding how it evolved helps you see why English poets made the structural choices they did, and why those choices shaped the way ideas unfold within the poem.
Origins of the English Sonnet Form
The sonnet began in 13th-century Sicily, where Giacomo da Lentini first developed the 14-line structure. In the 14th century, Petrarch refined the form and established its signature themes of courtly love, idealized beauty, and emotional longing. His influence was so dominant that the Italian sonnet is still called the Petrarchan sonnet.
The form arrived in England in the early 16th century through two key figures: Sir Thomas Wyatt and Henry Howard, Earl of Surrey. Wyatt translated and adapted Petrarch's sonnets into English, while Surrey developed a new rhyme scheme better suited to the English language (which has fewer natural rhymes than Italian).
From these adaptations, two major English sonnet forms emerged:
- Shakespearean (English) sonnet: Three quatrains and a closing couplet, rhyming ABAB CDCD EFEF GG. This structure lets the poet develop an idea across three stages before delivering a punchy conclusion or reversal in the final two lines.
- Spenserian sonnet: Uses interlocking rhymes (ABAB BCBC CDCD EE), which link the quatrains together more tightly. Edmund Spenser developed this variation, and the overlapping rhymes create a sense of continuity between sections that the Shakespearean form doesn't have.
Italian Influence on Renaissance Poetry
English sonneteers borrowed heavily from Petrarchan conventions, especially the figure of the idealized, often unattainable beloved. Courtly love themes carried over too: chivalric devotion, spiritual admiration, and the suffering of the unrequited lover.
Nature imagery was another major import. Italian poets used metaphors drawn from seasons, landscapes, and the natural world to mirror emotional states, and English poets adopted this practice enthusiastically.
The biggest departure from the Italian model was structural. The Petrarchan sonnet divides into an octave (8 lines) and a sestet (6 lines), with the turn between them. The English three-quatrain-plus-couplet form allowed for a more flexible progression of ideas, building an argument in stages rather than in two contrasting halves. Still, English sonnets retained the Italian commitment to exploring a single theme or argument within the tight space of 14 lines.
Themes and Characteristics
Central Themes
Renaissance sonnets returned to a core set of themes, but the best poets found fresh angles within them:
- Love in its many forms: romantic passion, spiritual devotion, and unrequited affection. Sonnet sequences often traced the arc of a relationship rather than capturing a single moment.
- Beauty, both physical and transcendent. Poets catalogued the beloved's features (eyes, lips, complexion) but also explored beauty as something beyond the physical.
- Mortality and time's passage. Shakespeare's Sonnet 18 ("Shall I compare thee to a summer's day?") argues that poetry can preserve beauty against decay. Sonnet 73 ("That time of year thou mayst in me behold") uses images of autumn, twilight, and dying embers to confront aging directly.
- The power of poetry itself. Many sonnets make the claim that verse can outlast human life, turning the poem into a kind of monument.
Formal Characteristics
- All English sonnets use iambic pentameter (ten syllables per line, alternating unstressed and stressed), which gives the form its rhythmic, almost musical quality.
- The volta (Italian for "turn") is a shift in tone, argument, or perspective within the poem. In Shakespearean sonnets, the volta most often arrives at line 9 (the start of the third quatrain) or at line 13 (the couplet). In Petrarchan sonnets, it falls between the octave and sestet.
- Conceits are extended metaphors sustained across part or all of a poem. In Sidney's Sonnet 71 from Astrophil and Stella, for instance, the beloved's face becomes a "book of Nature" that the reader must learn to interpret.
- The language is deliberately compressed. With only 14 lines to work with, poets pack in dense imagery, wordplay, and double meanings to maximize impact.
- Sonnets are typically addressed to a specific subject: a lover (Shakespeare's "Fair Youth" and "Dark Lady"), a patron, or even an abstract concept.
- Sonnet sequences became a major literary form in this period. These are interconnected series of sonnets that trace a relationship or emotional journey over time. Sidney's Astrophil and Stella (1591) was the first major English sequence and sparked a wave of imitations, including Spenser's Amoretti and Shakespeare's 154-sonnet collection.
