Was this His coming! I had hoped to see A scene of wondrous glory, as was told Of some great God who in a rain of gold Broke open bars and fell on Danae: Or a dread vision as when Semele Sickening for love and unappeased desire Prayed to see God’s clear body, and the fire Caught her brown limbs and slew her utterly: With such glad dreams I sought this holy place, And now with wondering eyes and heart I stand Before this supreme mystery of Love: Some kneeling girl with passionless pale face, An angel with a lily in his hand, And over both the white wings of a Dove.
Earth has not anything to show more fair: Dull would he be of soul who could pass by A sight so touching in its majesty: This City now doth, like a garment, wear The beauty of the morning; silent, bare, Ships, towers, domes, theatres, and temples lie Open unto the fields, and to the sky; All bright and glittering in the smokeless air. Never did sun more beautifully steep In his first splendour, valley, rock, or hill; Ne'er saw I, never felt, a calm so deep! The river glideth at his own sweet will: Dear God! the very houses seem asleep; And all that mighty heart is lying still!

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.
