"Leap from the crags, brave boy! The musing hills have kept thee long, But they have made thee strong, And fed thee with the fulness of their joy, And given direction that thou might'st return To me who yearn At foot of this great steep— Leap! leap!"
So the stream leapt Into his mother's arms, Who wept A space, Then calmed her sweet alarms, And smiled to see him as he slept, Wrapt in that dear embrace: And with the brooding of her tepid breast Cherished his mountain chillness— O, then—what rest! O, everywhere what stillness!
Never until the mankind making Bird beast and flower Fathering and all humbling darkness Tells with silence the last light breaking And the still hour Is come of the sea tumbling in harness
And I must enter again the round Zion of the water bead And the synagogue of the ear of corn Shall I let pray the shadow of a sound Or sow my salt seed In the least valley of sackcloth to mourn
The majesty and burning of the child's death. I shall not murder The mankind of her going with a grave truth Nor blaspheme down the stations of the breath With any further Elegy of innocence and youth.
Deep with the first dead lies London's daughter, Robed in the long friends, The grains beyond age, the dark veins of her mother, Secret by the unmourning water Of the riding Thames. After the first death, there is no other.

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.
