I know this pass. It runs between two kingdoms that raised their walls one shutter at a time, each shutter a little darker than the last, until the eastern one forgot how to open. The road through is one cart wide, and the carts stopped coming. At the bottom, where the road meets the old ring of standing stones, something small and wet came down the mountain and shook itself off. I have the drops to prove it. In the east the king keeps his night sealed, but the seal leaks. A few stars tunnelled out and live rough now in the dark stone, pale and pin-sized. I leave them bread at the gate, under a sky the colour of a closed door.

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
two radial fans of overlapping square-ended bands, meeting at a central seam
Movement
bands swing outward and upward from a centre below the bottom edge
Coverage
ink on about nine tenths of the paper
Tone
three tonal steps, weighted dark
Layering
many translucent passes of one kind, readable on the left, merging in right core
Edges
crisp straight band ends throughout; dry broken edges along the central seam
Feibai
none
Open paper
narrow vertical seam at centre, plus a pale band along the top
Chance marks
dark ink spatter at the seam's foot; pale water spots in right dark core
Frame
ink runs off left, right and bottom; top stays mostly open

Two fans of grey open from the foot of the paper and lean apart, split by a narrow white seam that runs from the top edge nearly to the bottom. Each fan is built from broad, square-ended bands swung round a centre below the sheet, so the image spreads outward like a ribcage.

The left fan is the finer instrument. Its bands step from a pale rim at the upper left into a deep core, and each pass stays legible through the next, because the self-sized paper keeps every layer at the surface. Where the band ends meet the seam they break into dry grain, and that rough edge keeps the gap alive.

The right fan pays for its weight. Its passes pile up until the core goes almost flat black, and the edges of the later bands are swallowed. A scatter of pale water spots shows through that dark. The spatter at the foot of the seam sits quietly and does no harm.

The result is a clear, well-built image with real depth on one side. It is held back by a dark that stopped being layers.

Measured

How it was read

Read by the Visual Analysis Engine, version 23.11, on 2026.10.26: 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: 0.049 (under 0.045 reads as flat).

FIVE READS

Five reads, agreeing on 3 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 is a close relative of R3, with layered radial fans either side of a central gap. It is heavier and more crowded, its right dark mass is less modelled inside, and small drips sit at the bottom centre.”

Form · FLUENT

Fan-shaped passes follow the brush's curved travel with clean, dry-edged ends at the central gap; the right dark block is bulky but still holds its arc.

WEAKEST Heavy dark fan block in right mass, slightly slab-like

STRONGEST Stepped arc bands of the left fan

Tonal depth · MODELLED

The left fan steps its density across overlapping bands. The right dark mass shows only faint grain and has modulation of 0.049, barely above flat.

WEAKEST Right dark mass interior, close to one dense tone

STRONGEST Left fan's stepped greys from pale rim to dark

Layering · ORDERED

Many translucent arc passes overlap in a readable order on both sides. The overlaps build depth, though the right side's darkest layers are hard to tell apart.

WEAKEST Deep right overlaps where passes merge toward black

STRONGEST Translucent overlapping fan passes on the left

Composition · WORKING

Two radiating fans on either side of a vertical gap create a strong focus, but 90% ink coverage leaves the edges crowded. The right mass is heavy and sits weightily.

WEAKEST Crowded heavy right mass with little breathing paper

STRONGEST Narrow central gap splitting the two fans

Material and surface · SOUND

The ink is controlled and the edge grain is well used. Small drips sit in the paper at the bottom centre, and faint droplet spots appear in the right dark mass, mostly in the stretched view.

WEAKEST Drip spatters at the bottom of the central gap

STRONGEST Dry-brush grain at the fan edges near the gap

FLAWS

3 distinct places, 1 major.

Each read must name every flaw and where it is, in a ninth of the sheet. Here the reads named flaws in 3 distinct places, 14 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. A major flaw holds Material and surface at rung 1.
