The white slot at the bottom is where it started. I am as sure of that as you can be of a crater. Everything after it is outflow: grey blades pushed off that point in rings, the faint ones at the rim older than the dark ones near home, the way light gets old crossing nothing. The black horseshoe is the part that couldn't leave. It sits there, heavy, a little stupid, holding the door shut on the first moment. Above it the paper is plain paper, clean as the dark between galaxies, and the outermost blade is still going, thinning, into a sky with no far wall.

The engine's reading

The reading

Written by the engine after the painting was rated, from the settled findings, and checked by hand before approval. It explains the numbers; it may not change them.

Structure
three radiating fans, left, top and right, joined at a dark horseshoe arch
Movement
outward from the central opening; the lower band and red verticals pull downward against it
Coverage
ink on about four fifths of the paper
Tone
five tonal steps, weighted dark
Layering
thin grey passes, dense dark passes, a red pass; readable at fan edges
Edges
crisp translucent blade ends in the fans; soft edges on red bands and dark slabs
Feibai
present at the tips of the top centre blades
Open paper
stepped skyline across the top; narrow white slot at bottom centre
Colour
red bands at lower left and around the right fan; pink patches beside the arch
Chance marks
paper creases across the grey blades; small specks and blots at right
Frame
ink runs off the bottom, left and right edges; the top stays open

A fan of grey blades opens from one small point above a white slot of paper. The blades climb out to the left, rise at the centre and swing out to the right, and every one leads the eye back down to the opening.

The upper fans carry it. At top left and top centre each blade is a thin grey pass laid over the last. The half-raw bark paper lets each pass dry with its edge intact, so the order of laying reads as stepped greys. At the tips of the top centre blades the brush split into flying white, and those tips cut the paper above into a stepped skyline. The red bands at lower left and right sit as their own clear pass.

The cost is below. The dark horseshoe around the opening, bulkiest right of the slot, is dense ink laid flat and sealed. Under it the lower band crowds the bottom edge and buries the earlier greys. Paper creases cross the blades, and the sheet absorbs them.

The plan reads from across a room. The upper blades repay standing close. The heavy base weighs on both without breaking them, and the sheet stands well above the archive's run, lifted by its top.

Measured

How it was read

Read by the Visual Analysis Engine, version 23.8, on 2026.10.06: measured by code, then read 5 times by Claude Opus 5.5 against three reference paintings (R1 to R3), each read independent of the others. How the engine works.

WHAT THE CODE SEES

Three views of one sheet.

Left, the photograph. Centre, the tone stretch the model is shown beside it: the darkest 45% of tones spread over the whole range, so flat black, banding and stains show. Right, every pixel as the measuring code classes it: cyan black ink, deep teal translucent grey, stone the palest ink, near black bare paper.

TONAL STEPS

READ 1, IN ITS OWN WORDS

“This sheet is related to R3: radial translucent layering around an arch opening, with good legible passes. It falls short because the darks are flat inside, the arch is slab-like and the bottom is crowded by near-total coverage.”

Form · BUILT

Radial wedges and arch bands hold their walls and follow the brush's sweep, but the heavy central arch and the lower-left rectangles stay slab-like and filled in.

WEAKEST Bulky dark arch band right of central opening

STRONGEST Radial fan blocks along the upper left arm

Tonal depth · MODELLED

The fan blades step through about five grey plateaus with dry-brush grain, but the dark arch and the lower-centre masses are flat inside (modulation 0.037).

WEAKEST Flat black arch around central opening

STRONGEST Graded translucent greys in the upper fan blades

Layering · ORDERED

Many translucent overlapping blades stay legible at their edges and build depth. The red bands sit as a clear separate pass beside the black.

WEAKEST Dense overlaps in the lower-centre darks lose some order

STRONGEST Stacked translucent blades in the left and right fans

Composition · WORKING

A strong radial arrangement leads to the white arch, and the empty paper at the top is shaped. But 81% coverage makes the lower half jammed and heavy.

WEAKEST Crowded, heavy lower band across the bottom edge

STRONGEST Radial fan converging on the central white opening

Material and surface · SOUND

The ink is controlled and the dry-brush edges are used well. The paper has faint creases, and the pale top-right wedge reads slightly cloudy. Nothing major sits in the principal darks.

WEAKEST Pale cloudy wash in the top-right triangle

STRONGEST Dry-brush edges on the fan blades

FLAWS

4 distinct places, 0 major.

Each read must name every flaw and where it is, in a ninth of the sheet. Here the reads named flaws in 4 distinct places, 10 mentions in all across 5 reads; the number in each ninth is how many times a flaw was named there. Reads agreeing on a place strengthen the evidence for one flaw; they do not multiply it.

GEOMETRY

Measured from the 16-bit master.

The previous engine (V22) measured this sheet's master file: 1 principal ink mass traced (cyan), 6 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 18 edge segments, 72% crisp, 28% soft or bloomed, 0% broken.

The rating these readings produce, the rules applied and the arithmetic, with Peter's own rating where he gave one, are in the Archive record.
