Abstract

This workshop introduces participants to two poetic forms with mathematical content, one ancient and one modern: the sestina and the Golden Shovel. Similarities and differences are highlighted and participants are guided through the process of writing their own poetry in each of these forms. At the end of the workshop, participants will have an opportunity to share their poetry. Educators who attend this workshop will find that the methods they learn can be easily adapted for secondary students or post-secondary students in a math course for non-science majors.

Introduction

In this workshop, we introduce two poetic forms and explore their mathematical possibilities. These forms are the sestina, a permutation-based 12th century form, and Golden Shovel, a constraint-based form created in the beginning of the 21st century. Although the creation of these two forms is separated by over 800 years, the forms share a striking similarity: each one fixes the last word of each line in the poem. The sestina relies on a recurring permutation to place the last words of each line. In contrast, the Golden Shovel relies on the post-modern technique of referencing a prior text. For the purpose of this paper, we discuss each form separately, however in the workshop setting, we will point out parallels and contrasts as they arise between the two forms.

The workshop will allocate 35 to 40 minutes to each form. Each portion will consist of a 10 — 15 minute introduction to the form, including advice on how to choose the 6 words (for the sestina) or quote (for the Golden Shovel). For participants who want more guidance, the workshop leaders will provide ideas for word choices as well as suitable quotes from a variety of mathematicians and physicists. After learning how to position the final words of each line, participants will spend the balance of time writing a poem (about 20 — 30 minutes for each form). During the last 10 to 15 minutes, we will invite participants to share one of their poems, as well as any observations or comparisons they have on the forms themselves. Depending on attendance and time constraints, this sharing might occur in small subgroups.

The Sestina

The sestina dates from late 12th century Provence and is attributed to troubadour Arnaut Daniel, whose poem Lo ferm voler qu’el cor m’intra (tr. The firm desire that enters) is the earliest known example of a sestina. Sestinas written by Dante and Petrarch in the 13th and 14th centuries helped spread the form and eventually it found its way to England, with the first English sestina penned by Edmund Spenser in the 16th century. In the last century, poets such as Elizabeth Bishop, Ezra Pound, W.H. Auden, and Marilyn Hacker have written sestinas [6]. Its continued use by such poets over a span of roughly 850 years is a testament to the sestina’s enduring appeal.

Though poets have experimented with minor variations on the sestina, an essential ingredient is that the six words that end the six lines of the first stanza, also end the six lines of the remaining 5 stanzas. As the poet transitions from one stanza to the next, a fixed permutation reorders the positions of these words. The sestina does not require a rhyming scheme, and perhaps this flexibility has played a role in its longevity. In its most common form, the permutation used is the same cyclic permutation that Arnaut Daniel introduced many centuries ago. This permutation is applied five times to produce a total of six stanzas, comprising 36 lines. Three additional lines follow the six stanzas, forming the tercet or envoi. The six

Dorf and Lajeunesse

words appear one last time in the tercet. Each line of the tercet contains two of the words, one of which ends the line. The order in which the six words appear in the tercet has a number of variations. Because of their frequent repetition, the six words become an echoing force, running like six separate threads through the poem and adding structure.

We can reconstruct the sestina’s pattern from Carol Dorf’s sestina Dust for My Sake included below. Table 1 shows the positions of the six words in each stanza. Each word is distinctly shaded to help us trace its changing position through the poem. Note that each word appears once in each row and column.

Table 1: End-of-line words in Carol Dorf’s “Dust for my Sake.”

Line 2connectsakekeepseaholdsthink
Line 3seaheldthinksconnectsakekeep
Line 4thinkinterconnectedsakekeepseahold
Line 5holdthinkdisconnectsakekeepssea
Line 6keepseaholdthinksconnectedsake

The permutation is reconstructed by examining how the positions of the words change from the 1st to the 2nd stanza. The reader will notice (for example) that the word that ends line 1 in each stanza always ends line 2 in the next. This is because the permutation describes not only how the words are reordered from the first to second stanza but also from each stanza to the one that follows.

This permutation is an example of a cycle, or cyclic permutation. Note that each word cycles through each possible position. If we follow the changing position of the word “sake” (highlighted in yellow in Table 1), we see it ends lines 1, 2, 4, 5, 3 and finally line 6 as it moves through the six stanzas. This sequence gives us the notation , for the sestina’s particular cyclic permutation.

We can think of the cyclic permutation as an infinite sequence of repeating positions

Thinking of it this way we can find the sequence of positions for any of the 6 words. For example, to map out the word “sea”, notice that it ends line 3 in the first stanza. We can read its position in the stanzas that follow by starting at any occurrence of 3 in the infinite sequence.

The permutation is called a cycle because if applied a time (to create a stanza) each word would return to its original position.

Dust for My Sake by Carol Dorf

Two notes: 1) I am dust. 2) For my sake the world was created. Together they connect despair and the grandiose, create the sea between worlds for neo-kabbalists to think into being; an earth with gravity to hold the atmosphere and the waters, to keep

all from shooting off into space, to keep each box of memory intact for the sake of the children who don’t forget being held against a mother’s chest, interconnected heartbeats giving both space to think again after infant misery and its sea

of tears. Walking a path above the sea shore she remembers rocking a child to keep the peace in a disintegrating house she thinks belonged to someone for whose sake she was told to hush, to disconnect impulse from expression, and to hold

still, god-dammit; what has become of her hold on the storyline? Bring back the sound of the sea with sanderlings rushing waves, that connect the earth and the oceans. Even now they keep sliding their thin beaks into the sands for the sake of their next meal but somehow she thinks

it refers to continuity, the way when we think of the long-gone complete with suitcases, it holds them in this world, not really for their sake but as a ballast against the rising sea which absorbs barrier islands and keeps reminding us that all the oceans are connected

underneath. We need to map connections as we build globes, however many ways we think up to distract ourselves, plans that keep enumerating distinctions that hold separate dust and sands that underlie the sea. Who has the chutzpah to say, “For my sake,

the planet keeps to its course, holds steady; when I think of the sea, I remember dust. For my sake.”

While the notation uniquely describes the permutation’s action, somehow it does not capture the elegance of the sestina’s permutation. For this, it is better to focus not on each word’s destination, but instead, on where each word came from. By examining the order in which the words are drawn from the previous stanza, we see that the word in line 1 of the stanza is from line 6 of the stanza, the word in line 2 of the stanza is from line 1 of the stanza etc. Continuing this analysis gives the pattern 6 1 5 2 4 3.

More simply, we look to the last line, then the line, then the last line, then the line, then the last line, then the line to draw the word order for the next stanza. At some point in the early 1960’s, Eugene Vinaver, professor of French at the University of Manchester, mentioned that the pattern of the sestina suggests a spiral [8]. Since then, the spiral image often appears in discussions of the sestina. The authors have created the diagram in Figure 1 to illustrate this spiral.

Sestina Music, the Septina and Beyond

The spiral pattern shown in Figure 1 is somewhat audible when reading a sestina aloud. In particular, the transition between stanzas draws our attention, because the word that ends one stanza echoes soon after in the first line of the next. However, one can argue that the best way to hear the sestina pattern is in music.

Lisa Lajeunesse composed Sestina Music (see [7]) to illustrate this pattern. It is based on a simple ascending sequence of 6 notes in C major: C D E F G A. These notes act like the 6 repeating words in a sestina. The music is shaped by this note sequence, as the notes are permuted to produce five more sequences. Each 6-note sequence forms a musical phrase that is analogous to one stanza of a sestina.

In the recording, the first two phrases (the equivalent of the first two stanzas) are heard in the bass (lower register) without any accompanying harmonies. This is to highlight the pattern of the sestina permutation for the listener as the music transitions from the first phrase to the next. Once this is established, the music returns to the beginning and repeats the phrase, but this time the bass notes are also the names (or roots) of the chords that are added to the treble (higher register) to accompany the bass line. Thus, we hear phrases in total:

When the first phrase is repeated, the accompanying 6-chord sequence: is added. The upper case letters refer to major chords, while the lower case refers to minor chords. Table 2 shows the bass note (also chord sequence) pattern for each phrase.

Of course, anyone interested in composing sestina-like music can vary the initial 6 notes that generate the musical pattern, just as a poet writing a sestina is free to choose any six words to end the lines of the poem. While composition of sestina music will not be part of the workshop discussion, we will play the brief musical excerpt for participants. We hope that hearing the music will broaden participants’ experience of the sestina by giving them an alternative, auditory perspective on its permutation pattern.

Jacques Roubaud of the French literary group Oulipo adapted the sestina’s spiral pattern to create a septina [8] based on . The septina introduces a seventh word and a seventh stanza. Unfortunately, the permutation that strictly follows the spiraling pattern does not produce a 7-cycle. The permutation obtained from the spiral pattern is . This leads to a number of un-sestina-like effects. The , , and words form a 4-cycle. The words in lines 3 and 6 form a 2-cycle (swapping positions from one stanza to the next), and the last word of line 5 remains fixed throughout. Roubaud was able to mitigate these problems by adapting the pattern and using only six lines in each stanza. Thus, each stanza is missing one of the 7 words. Oulipian Harry Mathews’ septina Safety in Numbers can be found at [9] as an example of this form.

Roubaud and mathematicians who followed investigated the question: for what values of (other than ) does a sestina-like permutation lead to a cycle on elements? The result is surprisingly complex. A simple investigation of the positive integers between 3 and 12 leads to success with numbers 3, 5, 6, 9 and 11 only. The interested reader can learn more about why some numbers work and others do not in [10].

The Golden Shovel

The Golden Shovel is a new poetic form created by Terrance Hayes in honor of Gwendolyn Brooks [5]. The last word of each line in a Golden Shovel is taken in order from a line of the writer the poet is honoring. The results can be quite different from the original poem. It shares something with the cento or the erasure, in incorporating another writer’s words into the poem. In the Golden Shovel the effect is additive as the poet brings their own words into dialogue with the words of the writer to whom they are paying tribute.

Dorf and Lajeunesse

The Golden Shovel provides the poet with two unique opportunities. First, as discussed in the explanation of its construction, it can serve as homage to another scholar. Because the writer of the originating text can come from any realm, the chain of end words in the Golden Shovel is a way to incorporate the work of other mathematicians into our poetry. Secondly, the form presents an interesting challenge in terms of creating line breaks.

Where to break the line is a central conundrum in writing poetry. Poets use a variety of techniques to create line breaks. Historically, the primary method was to count the stresses in a line. For example in the line “The rain in Spain falls mainly on the plain,” there are 10 syllables, and 5 stressed words (rain, Spain, main, on, plain). This particular pattern is one of the most common in English and is called iambic pentameter. There are many other syllabic patterns. In contemporary English verse, many poets count stresses, or syllables in constructing line lengths, but few use rigid patterns such as iambic pentameter. Another common practice is to insert line breaks at the end of an important thought or word. This is illustrated in Chana Bloch’s poem At the Border [1].

At the Border by Chana Bloch (for Nina)

My hand slips past the guardrail of the hospital bed,

date of birth on my wristband, date of death postponed.

By the grace of a scalpel blade

I have made it across the border just

in time. My blessing hand rests on Nina’s great naked belly,

Liliana treading water, headed for land,

her millions of eggs already alive inside.

In this poem, each line ends either on a grammatical unit such as headed for land, or an important word such as guardrail. This technique allows the reader a moment to pause before going on to the next unit of thought.

In contrast, the Golden Shovel relies on the technique of using each word of the original quote as the last word of the line. In the poem, Ask For A Universe shown below, Dorf uses a quote about dark matter

592

Sestinas and Golden Shovels

by astronomer and cosmologist Beatrice Tinsley [4]. The full abstract from a paper on which Tinsley is a co-author reads

A variety of arguments suggest that the density of the universe is no more than a tenth of the value required for closure. Loopholes in this reasoning may exist, but if so, they are primordial and invisible, or perhaps just black.

The words of the second line from the abstract become the last words in the lines of the Golden Shovel. They are shown in bold below for the purpose of this discussion. The form facilitates the discussion of an idea with someone one may or may not know in real life, as the poet was able to reflect on in [2].

Ask for a universe and what do you get? by Carol Dorf

(a Golden Shovel for Beatrice Tinsley)

For a while scientists’ proposed loopholes

crossing the universe, wormholes a technique in

which to traverse distance to other worlds, this

unpleasant constraint which most reasoning

holds us to a single solar system or may

be, just perhaps a transit could exist

to get us to Proxima Centauri but

travelling 4.25 light years is a big if -

human tolerance of forces matter - so

most likely our AI will proceed us and they

will send back slow data just to say We are

fine and happy in the primordial

reaches of space making the invisible

visible while we observe expansion - or

it is possible we will forget them perhaps

because the heat becomes unbearable or maybe just

because too close to light we lose night’s black.

Dorf and Lajeunesse

Summary and Conclusions

The sestina and Golden Shovel offer an ideal opportunity to combine mathematics with poetry. The sestina has a mathematical permutation at the heart of its form. The Golden Shovel provides an opportunity to pay homage to a mathematician or a mathematical idea through poetry. The sestina, an ancient form, may seem likely to contrast the modern form of the Golden Shovel. However, when placed side-by-side in this workshop, the similarity between these forms will appear in relief. By fixing the last word of each line and constraining the poet’s choices in the same way, writing poetry in each of these forms becomes a strikingly similar experience.

Participants in this workshop will not only have the opportunity to learn about two poetic forms, but also experience the poetic forms first-hand by writing a sestina and a Golden Shovel of their own. They will also have the opportunity to share their poetry with one another. Educators who would like to introduce their own students to the sestina or Golden Shovel forms can easily reproduce the structure of the workshop and the materials used in their own classrooms. Both groups will see first-hand how fixing the last words of each line in a poem can help lead the poet to the poem.
