The Sestina: A Mathematical Dance of Words

The sestina stands as one of the most intricate puzzles in the canon of poetic forms. Born among the troubadours of medieval Provence, specifically attributed to the twelfth-century poet Arnaut Daniel, it is a structure built not on rhyme, but on obsessive repetition. Dante Alighieri admired Daniel’s invention enough to carry it into Italian poetry, cementing its legacy as a form that challenges the writer to weave a cohesive narrative through a rigid, spiraling pattern.

Unlike the villanelle or the triolet, which rely heavily on refrains and rhymes, the sestina demands a different kind of discipline: the recycling of six specific end-words across thirty-nine lines.

The Architecture of Obsession

The classic sestina is unrhymed. It consists of six stanzas of six lines each (sestets), followed by a closing stanza of three lines (the envoi or tornada).

The challenge-and the beauty-lies in the end-words. You choose six words to end the lines of the first stanza. These six words then repeat as the end-words for every subsequent line in the poem, but in a specific, rotating order.

The Spiral Pattern

If we label the end-words of the first stanza as A, B, C, D, E, and F, the pattern for the second stanza is not random. It follows a “bottom-up, top-down” spiral: take the last word of the previous stanza (F), then the first (A), then the second-to-last (E), then the second (B), and so on.

The permutation for Stanza 2 becomes: F, A, E, B, D, C.

By applying this reordering logic to each subsequent stanza, the full map of the poem emerges:

• Stanza 1: A B C D E F
• Stanza 2: F A E B D C
• Stanza 3: C F D A B E
• Stanza 4: E C B F A D
• Stanza 5: D E A C F B
• Stanza 6: B D F E C A

The Envoi

The poem concludes with a three-line stanza. This brief coda must include all six of the repeating words. Traditionally, three words appear at the end of the lines, and the other three are tucked somewhere inside the lines.

While purists argue for the strict pattern of (B) E, (D) C, (A) F, modern poets often shift this to simpler arrangements, such as (A) B, (C) D, (E) F.

Evolution: The Circular Sestina

In the 19th century, a variation emerged introducing rhyme to the equation. The “Circular” or “Rhyming Sestina” organizes the six words into two rhyming sets (A, C, E rhyme together; B, D, F rhyme together).

To maintain an alternating rhyme scheme (ababab) throughout the poem, the standard spiral pattern is modified. For example, the second stanza in a circular sestina might shift to F A D E B C rather than the standard F A E B D C.

A Masterclass in Repetition

The form saw a resurgence in the 1930s, often used for lighter, witty verse, though its repetitive nature makes it equally suited for themes of grief, obsession, or monotony.

Elizabeth Bishop’s poem, simply titled Sestina, remains the gold standard for the modern era. Bishop avoids high drama, focusing instead on a domestic scene: a grandmother, a child, and a stove. She selects six mundane, heavy nouns: house, grandmother, child, stove, almanac, tears.

Through the rotation, the atmosphere shifts. The “tears” move from the grandmother’s eyes to the teakettle, then to the almanac, and finally to a drawing by the child. The rigid form mirrors the trapped, cyclical nature of hidden grief within a home.

How to Build Your Own

Writing a sestina is less about sudden inspiration and more about architectural planning. It requires a process.

1. Select Your Subject and Meter

Start with a familiar narrative. Since the form is long (39 lines), you need a story with enough room to breathe. While free verse is acceptable, a steady meter-like iambic pentameter-helps drive the repetitive words forward naturally, preventing the poem from stalling.

2. Choose the Six Words

This is the critical step. These six words will appear seven times each.

• Avoid: Generic connectors or words with little semantic weight.
• Be Careful With: Verbs that only work in one tense.
• Embrace: Concrete nouns with multiple meanings (polysemes) or flexible imagery.

For example, in his police procedural sestina The Job, poet Dusty Grein selected words evoking the gritty noir of detective work: Job, Badge, Protect, Crime, Report, Night.

3. Construct the Scaffolding

Don’t try to keep the pattern in your head. Write down the end-words for all 39 lines on the right side of your page before composing a single sentence. This creates a “fill-in-the-blanks” framework.

In The Job, Grein sets up the first stanza to establish the scene:

It feels like forever I’ve been on the job. (A) Pinned down by the weight of my gun and my badge; (B) my duty is etched there, to serve and protect. (C) The uniforms tape off the scene of the crime (D) at this point, there still isn’t much to report, (E) It promises to be one hell of a night. (F)

4. Connect the Dots

With the end-words fixed, your task is to write lines that lead naturally to them. The difficulty increases in the middle stanzas (3 and 4), where the juxtaposition of words becomes less intuitive. This friction often forces creative, unexpected metaphors.

As the poem progresses, the meanings of the words should evolve. In Grein’s final envoi, the words converge to resolve the detective’s internal conflict:

“Now, wearing my badge is more than just a job,” I repeat this each night as I write my report. “By solving these crimes, my whole world I protect.”

The Final Challenge

The sestina is a paradox: it is a cage that forces the bird to sing louder. The strict constraints can liberate a writer from the paralysis of infinite choice. By focusing on the puzzle of the six words, the subconscious is often tricked into revealing deeper emotional truths.

Challenge yourself to draft one. The first few stanzas may feel mechanical, but as the spiral tightens, you may find the form writing the story for you.
