The black band is the wall the queen ordered built in a single night, square at the top because the masons ran out of moon. The drips along its crown are where they set down their buckets. Beyond it the pale fans are the provinces that never answered the summons, faint on the parchment, still argued over at court. I like the wall. It does not ring when you knock on it, which is a flaw in a spell and a virtue in a wall. Down by the curl of the tide, a few drops have fallen onto the white and lie there like buttons torn from a traveller who was running, and did not go back for them.

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
nested concentric arcs; pale fans left, mid-grey arc centre, black and grey bands right
Movement
clockwise rotation from upper left down to right edge; the lower tail curls back inward
Coverage
ink on about three quarters of the paper
Tone
three tonal steps, weighted to the middle greys
Layering
pale, mid-grey and black passes; readable at band edges, upper left and centre
Edges
crisp black band walls and squared top; soft, feathered pale fans; broken bristle ends on tail
Feibai
present in the curling tail and inner grey arc at lower centre
Open paper
broad white wedge at lower left, shaped by the curl of the tail
Chance marks
drips and blots atop black band; drops below tail at centre-left; bluish spots at right edge
Frame
ink runs off top, right and bottom; left edge and lower left stay open

The arcs turn clockwise, from pale fans at the upper left through a mid-grey band to a black wall at the right, with a grey band beyond it running off the paper. Low in the middle a grey tail curls back into the white and gives the empty lower left a shape of its own.

The greys hold the sheet. Raw bark paper grips a drier brush hard, so the mid-grey arc and the tail keep every bristle track: streaks running with the stroke, white paper flashing through where the hairs parted at speed. Where the black crosses the grey, the order of passes reads at the edge.

The black is where the sheet goes quiet. Laid that heavy, the ink seals the paper and drowns the bristle tracks, so the band sits flat beside the striated greys, its square top bled into small blots. The palest arcs at the upper left barely register, and the weight crowds right. Drops under the tail and fine crease lines are small; the sheet absorbs them.

The turn and the greys keep it standing. Its heaviest passage is its least alive, which leaves a well-made sheet short of a remarkable one.

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

3 families of tone.

Every inked pixel's brightness in 64 bins, smoothed; each circled peak holds at least 4% of the ink. Life inside the black: 0.038 (under 0.045 reads as flat).

FIVE READS

Five reads, agreeing on 2 of 5 qualities.

Each quality placed on its ladder by each read, and the mean the engine keeps. Where reads differ, they differ by one rung; close calls resolve down.

READ 1, IN ITS OWN WORDS

“This sheet of concentric arcs echoes R3 but is thinner: the black arc is flat inside, the layering is simple, the upper left is weak, and drips mark the black arc's top edge. An ordinary, working sheet.”

Form · BUILT

Concentric arcs hold and follow the brush's travel; the dark arc's top end is cut square, and the pale left arcs dissolve into soft, loose edges.

WEAKEST Blunt squared top end of dark arc with drips

STRONGEST Mid-grey arc sweeping into dry-brush tail

Tonal depth · MODELLED

Grey bands show bristle streaks and graded tone; the measured dark-interior modulation is under the flat threshold, with only faint banding in the black arc; three tonal steps.

WEAKEST Dark arc interior largely flat (modulation 0.038)

STRONGEST Grey arcs streaked with bristle grain and arcs

Layering · LEGIBLE

Pale, mid-grey and black arc passes overlap translucently and stay readable, but the order is simple and the overlaps add little depth.

WEAKEST Pale left arcs barely register as a pass

STRONGEST Black arc laid over the mid-grey band, legible

Composition · WORKING

The rotating arcs give a strong clockwise direction and the lower-left void is shaped; the upper left is pale and weak, and the weight is crowded right.

WEAKEST Washed-out upper-left quarter

STRONGEST Sweeping spiral carrying eye to lower right

Material and surface · FLAWED

Small runs and blots sit on the top edge of the black arc, drops trail below the grey arc at centre-left, crease lines cross the grey bands, and there are bluish spots at the right edge.

WEAKEST Drips and blots at top of black arc

STRONGEST Dry-brush grain in grey arc tail

FLAWS

5 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 5 distinct places, 17 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: 3 principal ink masses traced (cyan), 6 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 19 edge segments, 32% crisp, 47% soft or bloomed, 21% broken.
