The Poetry of earth is never dead: When all the birds are faint with the hot sun, And hide in cooling trees, a voice will run From hedge to hedge about the new-mown mead; That is the Grasshopper's—he takes the lead In summer luxury,—he has never done With his delights; for when tired out with fun He rests at ease beneath some pleasant weed. The poetry of earth is ceasing never: On a lone winter evening, when the frost Has wrought a silence, from the stove there shrills The Cricket's song, in warmth increasing ever, And seems to one in drowsiness half lost, The Grasshopper's among some grassy hills.
Haydon! forgive me that I cannot speak Definitively on these mighty things; Forgive me that I have not Eagle's wings— That what I want I know not where to seek: And think that I would not be over meek In rolling out upfollow'd thunderings, Even to the steep of Heliconian springs, Were I of ample strength for such a freak— Think too, that all those numbers should be thine; Whose else? In this who touch thy vesture's hem? For when men star'd at what was most divine With browless idiotism—o'erwise phlegm— Thou hadst beheld the Hesperean shine Of their star in the East, and gone to worship them.

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.
