Thou comest, Autumn, heralded by the rain, With banners, by great gales incessant fanned, Brighter than brightest silks of Samarcand, And stately oxen harnessed to thy wain! Thou standest, like imperial Charlemagne, Upon thy bridge of gold; thy royal hand Outstretched with benedictions o'er the land, Blessing the farms through all thy vast domain! Thy shield is the red harvest moon, suspended So long beneath the heaven's o'er-hanging eaves; Thy steps are by the farmer's prayers attended; Like flames upon an altar shine the sheaves; And, following thee, in thy ovation splendid, Thine almoner, the wind, scatters the golden leaves!
She is gamesome and good, But of mutable mood,— No dreary repeater now and again, She will be all things to all men. She who is old, but nowise feeble, Pours her power into the people, Merry and manifold without bar, Makes and moulds them what they are, And what they call their city way Is not their way, but hers, And what they say they made to-day, They learned of the oaks and firs. She spawneth men as mallows fresh, Hero and maiden, flesh of her flesh; She drugs her water and her wheat With the flavors she finds meet, And gives them what to drink and eat; And having thus their bread and growth, They do her bidding, nothing loath. What's most theirs is not their own, But borrowed in atoms from iron and stone, And in their vaunted works of Art The master-stroke is still her part.

How this picture is made
What a fractal is
A fractal is a shape that keeps its pattern when you look closer. Coastlines, trees, shells, and weather do this. The large form and the small form are the same kind of thing. A poem can be drawn that way. The shape of the whole comes from the shape of the lines.
Primunia is the name for the source of that order: the pattern under the pattern, already there in a tree, a shell, and a verse.
How the boundary is drawn
The number under the picture is the poem constant. It is read from the build of the lines: their length, how uneven they are, the size of the stanzas, the share of vowels, and the way the lines end. A new word moves the number when it changes that build. The same poem always gives the same number.
Drawn on its own, that number sits in a quiet part of the plane, and most poems would look like the same soft disk. So the number is carried outward along its own direction until it meets the edge of the Mandelbrot set, where the shape turns sharp. The picture is the Julia set of that meeting place.
Each point on the canvas is folded again and again by one small rule. Points that stay near the rule form the dark interior. Points that rush away become the coloured bands. The hue comes from the poem constant, and the brightest bands turn toward gold. Change the length of a line, the stanza, or the vowel share, and both the number and the picture move.
What the branching signifies
Branching draws the poem as a tree. Each turn follows a line, and every smaller branch repeats that pattern. A longer line reaches farther. The letters at the start of a line bend the next turn. A higher share of vowels opens the branches wider.
The trunk takes its colour from the poem constant and warms toward gold at the tips. When the poem has more than one stanza, gold forks leave the trunk. Each fork is a stanza beyond the first, up to three. The tree divides where the poem divides. One stanza remains a single trunk.
