*Arma virumque cano* – ‘I sing of arms and the man’. With these resonant words Virgil opens his great epic the *Aeneid*, composed over two thousand years ago. The poem, which is nearly ten thousand lines long, is written almost entirely in dactylic hexameter – an astonishing feat of constrained writing, especially when we consider that Virgil lacked the convenience of our modern-day word processing and editing tools.

# Routes through a poem

Sometime during the fourth century, in northwest China, a woman named Su Hui picked up her silk thread and embarked on an embroidery project. The result was an extraordinary work of visual poetry – a grid of 29 x 29 characters, shuttle-woven on brocade to form a palindrome poem that would become known as *Xuanji Tu*, or the ‘Star Gauge’.

# Farewell to 2021

As we approach the end of a year dominated by chaos, bleakness, and the ravages of the pandemic, it is difficult not to succumb to despair. We seem to be caught up in the ‘widening gyre’ of Yeats:

Things fall apart; the centre cannot hold; Mere anarchy is loosed upon the world

Yeats wrote ‘The Second Coming’ in January 1919, at a time when the First World War had only recently ended, the political situation in his native Ireland was dangerously unstable and the Spanish ‘flu pandemic was raging (his pregnant wife Georgie Hyde-Lees became very ill and almost died from the ‘flu). It’s hardly surprising that a sense of impending doom reverberates through the poem.

I used to loathe coordinate geometry at school, mainly because we had to calculate, plot and draw the graphs by hand. My geometry notebooks were full of wobbly parabolas and ellipses that staggered uncertainly from point to point rather than flowing in one smooth, continuous curve.

In his 1982 book ‘*The Fractal Geometry of Nature’* the mathematician Benoit Mandelbrot explored ‘irregular and fragmented patterns around us’ that ‘tend to be *scaling*, implying that the degree of their irregularity and/or fragmentation is identical at all scales.’

He called this family of shapes fractals, from the Latin adjective *fractus*, meaning fragmented or irregular. Such objects, Mandelbrot noted, are present in nature as well as in a wide range of fields.

# Intersections – Poetry, Mathematics and JoAnne Growney

Emmy Noether was one of the great mathematicians of the early 20^{th} century. Born in Bavaria in 1882, she loved dancing and initially trained to be a language teacher before opting, despite numerous obstacles, to study mathematics at university. She went on to make significant contributions in many areas of mathematics and mathematical physics, most notably in the field of abstract algebra.

# Mathematical forms in poetry 5 – number sequences

Sometime around 1550 BC an Egyptian scribe named Ahmes noted down a method for obtaining the area of a circle, in what is the earliest recorded attempt to evaluate the number we know as 𝜋.

The history of 𝜋 (its symbol is the Greek letter pi) is fascinating, as are its many applications in poetry. To 16 digits, the expansion of 𝜋 is

𝜋 = 3.141592653589793.

Permutations are a feature of many poetic forms: rhyme and metrical patterns, the arrangement of lines in a villanelle or pantoum, the rotation of end-words through the stanzas of a sestina. Ruth Holzer’s ‘*For Dylan Thomas on His Hundredth Birthday’* is an example of a sestina by a contemporary poet, with end-words* wild, sky*, *end*, *hills*, *wave*, *love*.

# Review – The Utu Sonnets by Anthony Etherin

‘Poetry is the mathematics of writing,’ John Steinbeck observed, ‘and closely kin to music.’ If we accept Steinbeck’s analogy, then Anthony Etherin’s *The Utu Sonnets* is the poetic equivalent of the purest of pure mathematics. In previous publications such as his 2019 collection Stray Arts (and Other Inventions) Etherin has proved himself a master of constrained writing, pushing the boundaries of form in tightly crafted palindromes, exact anagrams and dazzlingly inventive sonnets. The seven sonnets presented here are his most constrained work to date.

# Review – A Celestial Crown of Sonnets by Sam Illingworth & Stephen Paul Wren

Sometime in the 4^{th} century BC, a Chinese astronomer named Shi Shen took it upon himself to map the stars visible in the night sky. The resulting work, containing some 800 stars, is generally considered to be the earliest star catalogue. Shi Shen’s achievements did not stop there; he also observed sunspots and wrote a number of astronomical and astrological treatises. In recognition of his contributions to astronomy, a crater on the far side of the moon has been named after him.

With my Eurocentric education I hadn’t heard of Shi Shen before reading *A Celestial Crown of Sonnets*, written by Sam Illingworth and Stephen Paul Wren. Each poem in this slim, beautifully produced volume focuses on an astronomer who made significant contributions to the advancement of our understanding of the universe.
