Short answer

A Petrarchan sonnet (also called an Italian sonnet) is a fourteen-line poem that divides into an eight-line octet and a six-line sestet, separated by a turning point called the volta. It is the oldest sonnet form, developed by the Italian poet Petrarch in the fourteenth century and hugely influential on English poetry.

What is the structure of a Petrarchan sonnet?

The Petrarchan sonnet has a two-part structure that is central to its meaning. Unlike the Shakespearean sonnet, which builds through three quatrains before a final couplet, the Petrarchan form divides into a longer first movement and a shorter response:

  • The octet (lines 1–8): typically rhymes ABBA ABBA. It introduces a problem, a situation, a question, or an emotional state.
  • The volta (the "turn"): at or around line 9, the poem pivots — the thought shifts, complications arise, or the perspective changes.
  • The sestet (lines 9–14): typically rhymes in one of several patterns (CDECDE, CDCDCD, or CDCCDC). It develops, resolves, or complicates what the octet established.

The volta is the structural heart of the Petrarchan sonnet. It is the moment of change — intellectual, emotional, or tonal — that gives the fourteen lines their internal tension and unity.

How does the Petrarchan sonnet differ from the Shakespearean form?

Feature Petrarchan sonnet Shakespearean sonnet
Origin Italy (Petrarch, 14th century) England (Shakespeare, 16th century)
Structure Octet (8 lines) + sestet (6 lines) Three quatrains (4+4+4 lines) + couplet (2 lines)
Rhyme scheme ABBA ABBA + CDECDE (or variants) ABAB CDCD EFEF GG
Volta position Between octet and sestet (line 9) Often at the couplet (line 13)
Rhyme at the end No final couplet Final rhyming couplet
Typical effect More sustained argument; turn feels more gradual More epigrammatic; couplet delivers a punch

Neither form is superior — they create different effects. The Petrarchan volta at line 9 allows for a more balanced interplay between problem and response; the Shakespearean couplet delivers a compressed, often witty resolution.

What themes did Petrarch — and later English poets — use the form for?

Petrarch wrote a sequence of 366 sonnets called Canzoniere (or Rime Sparse) addressed to Laura, a woman he loved but could never possess. This established the Petrarchan convention: the sonnet as a vehicle for unrequited love, the beloved as perfect and unattainable, the speaker as suffering but eloquent.

English poets adopted and then subverted these conventions:

  • Sir Philip Sidney (Astrophil and Stella, 1590s) used the Petrarchan form to explore genuine psychological conflict in the lover-speaker.
  • John Milton adapted the Petrarchan structure for political and religious subjects — arguing that the form's sustained argument could carry serious public as well as private themes.
  • Elizabeth Barrett Browning (Sonnets from the Portuguese, 1850) used modified Petrarchan sonnets to write about mutual, reciprocal love — deliberately departing from the Petrarchan tradition of the male speaker and the passive beloved.

How do I analyse a Petrarchan sonnet?

A strong analysis does three things: it identifies the structure, locates the volta, and explains how the content of octet and sestet relate.

Worked example using Milton's "When I Consider How My Light Is Spent" (1652):

  • Octet (lines 1–8): The speaker laments losing his sight before using his talent in God's service — "that one Talent which is death to hide / Lodged with me useless."
  • Volta (line 8–9): "But Patience, to prevent / That murmur, soon replies" — a turn from complaint to instruction.
  • Sestet (lines 9–14): Patience corrects the speaker: God does not need human service; "They also serve who only stand and wait."

Analysis: Milton uses the Petrarchan structure to enact the poem's argument. The octet represents the speaker's human perspective — limited, frustrated, questioning. The sestet represents the divine correction. The volta is not decorative; it is the theological pivot of the poem. The structure and the meaning are inseparable.

Can I write a Petrarchan sonnet myself?

Yes, and it is a productive exercise. The ABBA ABBA rhyme scheme for the octet is its most challenging feature — finding two sets of four lines with only two rhyme sounds requires planning. Try:

  • Choose your octet's rhyme sounds first, before writing a line.
  • Decide what the octet will set up — a question, a tension, a problem — and what the sestet will do with it.
  • The volta is your best opportunity: use it to genuinely shift perspective, not just to change the subject.
  • The sestet's rhyme scheme is more flexible — CDECDE is traditional, but modern practitioners often vary it.

Writing a sonnet is one of the most efficient ways to understand how form and meaning interact.

Frequently asked questions

Is the Petrarchan sonnet always about love?

No — love was Petrarch's subject, but the form has been used for political argument, religious meditation, social commentary, and personal grief. Milton's sonnets use the Petrarchan structure for subjects ranging from blindness to the massacre of Protestant communities in the Alps. The form is neutral; it is the tradition of its use that associates it with love poetry.

What is the difference between the octet and the octave?

They are the same thing under different names. Octet and octave both describe the eight-line first section of a Petrarchan sonnet. "Octave" is the more common term in academic writing; "octet" is also acceptable. Similarly, the six-line second section is called the sestet or, occasionally, the sestet.

What is a Spenserian sonnet and how does it fit in?

The Spenserian sonnet (developed by Edmund Spenser) is a third variant, which links the Shakespearean structure with interlocking rhymes: ABAB BCBC CDCD EE. It creates more continuity between stanzas than the Shakespearean form but retains the closing couplet. It sits between Petrarchan and Shakespearean in structure and is less commonly discussed at KS3, though it is worth knowing exists.

Do modern poets still write Petrarchan sonnets?

Yes. The sonnet in all its forms remains one of the most widely used forms in contemporary poetry. Modern poets often use it as a container they deliberately press against — working within or subverting the Petrarchan conventions of unrequited love, the elevated beloved, and the suffering speaker. Carol Ann Duffy and Seamus Heaney, for example, have both written sonnets that consciously engage with and depart from Petrarchan tradition.
