The heart once broken is a heart no more, And is absolved from all a heart must be; All that it signed or chartered heretofore Is cancelled now, the bankrupt heart is free; So much of duty as you may require Of shards and dust, this and no more of pain, This and no more of hope, remorse, desire, The heart once broken need support again. How simple ’tis, and what a little sound It makes in breaking, let the world attest: It struggles, and it fails; the world goes round, And the moon follows it. Heart in my breast, ’Tis half a year now since you broke in two; The world’s forgotten well, if the world knew.
In Xanadu did Kubla Khan A stately pleasure-dome decree: Where Alph, the sacred river, ran Through caverns measureless to man Down to a sunless sea. So twice five miles of fertile ground With walls and towers were girdled round; And there were gardens bright with sinuous rills, Where blossomed many an incense-bearing tree; And here were forests ancient as the hills, Enfolding sunny spots of greenery.
But oh! that deep romantic chasm which slanted Down the green hill athwart a cedarn cover! A savage place! as holy and enchanted As e’er beneath a waning moon was haunted By woman wailing for her demon-lover! And from this chasm, with ceaseless turmoil seething, As if this earth in fast thick pants were breathing, A mighty fountain momently was forced: Amid whose swift half-intermitted burst Huge fragments vaulted like rebounding hail, Or chaffy grain beneath the thresher’s flail: And mid these dancing rocks at once and ever It flung up momently the sacred river. Five miles meandering with a mazy motion Through wood and dale the sacred river ran, Then reached the caverns measureless to man, And sank in tumult to a lifeless ocean; And ’mid this tumult Kubla heard from far Ancestral voices prophesying war! The shadow of the dome of pleasure Floated midway on the waves; Where was heard the mingled measure From the fountain and the caves. It was a miracle of rare device, A sunny pleasure-dome with caves of ice!
A damsel with a dulcimer In a vision once I saw: It was an Abyssinian maid And on her dulcimer she played, Singing of Mount Abora. Could I revive within me Her symphony and song, To such a deep delight ’twould win me, That with music loud and long, I would build that dome in air, That sunny dome! those caves of ice! And all who heard should see them there, And all should cry, Beware! Beware! His flashing eyes, his floating hair! Weave a circle round him thrice, And close your eyes with holy dread For he on honey-dew hath fed, And drunk the milk of Paradise.

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.
