Look down a deep enough well and the moon is at the bottom, small and white and perfectly round. The old story says the monkeys saw it there and made a chain of themselves, hand to tail, to fish it out. Everyone laughs at the monkeys. I was the one on the end. The walls go past in slabs, each course of stone a shade darker than the last, and the cold comes up off the water like a held breath. Above me, hands and tails all the way to the sky, every grip holding. Below me, the moon, starting to tremble, because my fingertips have just touched the water.

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
small white disc hub, broad wedge spokes, pale arcs ringing behind them
Movement
radial outward from the hub; pale concentric arcs circle across the spokes
Coverage
ink on about nine tenths of the paper
Tone
four tonal steps, weighted dark
Layering
many translucent wedge passes; order clearest in upper-right fan, thickening lower centre
Edges
crisp squared ends on dark wedges; softer streaked ends on outer arcs; crisp hub rim
Feibai
present in the pale arcs above the hub and the narrow gap below it
Open paper
small round white disc just above centre, the only bare reserve
Chance marks
small dark specks near top-right edge; cloudy grey wash at left edge
Frame
ink runs off all four edges; corners lighten to pale grey arcs

A wheel of ink turns around a small white disc set just above the middle of a long sheet. Wide wedges of black and grey fan out on every side and run off all four edges. The eye is pulled into the hub and thrown back out in the same look.

The upper-right fan is the best of it. Translucent wedges stack there in an order you can read. Each earlier pass shows its edge through the later one, and the greys step down in bands. Half-raw paper keeps the layers from sinking together. Above the hub and down the narrow gap below it, pale arcs break into flying white, bare paper streaking with the turn of the brush. Those streaks keep the wheel moving.

The cost is weight. The lower half is packed. The dark mass at bottom centre is nearly even in tone and faintly brown, with little air around it. At upper left a large slab stops on a blunt squared end, filled more than travelled.

Those are real drags on one side of the wheel. It turns anyway. The hub holds, the layering builds real depth, and the sheet sits well above the archive's common run.

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

4 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: 0.064 (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

“A radial burst in the same family as R3, with legible stacked passes. It is heavier and more crowded, with blunter slab wedges and darks in the lower half that read flatter.”

Form · BUILT

Radial wedge strokes hold their walls and follow the arc, but lower-right and left dark wedges read as squared, slab-like blocks with blunt ends.

WEAKEST Bulky dark rectangular wedges, lower right

STRONGEST Upper-right radial fan strokes following the arc

Tonal depth · MODELLED

Stretched view shows banding and grain in most wedges (modulation 0.064, four steps), but the large lower-centre and lower-right darks read flat at viewing distance.

WEAKEST Dense lower-centre dark mass near-uniform in colour view

STRONGEST Upper-right fan with banded, stepped greys

Layering · ORDERED

Many translucent radial passes stacked in readable order; overlaps step tone outward across the sheet, though the lower-centre stack thickens toward opacity.

WEAKEST Lower centre where stacked darks merge

STRONGEST Overlapping translucent wedges in upper right

Composition · WORKING

Radial burst around a white centre gives clear direction, but 93% coverage crowds the frame; corners and lower half feel jammed and heavy.

WEAKEST Crowded, near-total coverage leaves little shaped paper

STRONGEST Central white circle anchoring the radial burst

Material and surface · SOUND

Ink controlled with streaked dry-brush edges; small specks top right and a cloudy grey patch at mid-left sit away from principal darks.

WEAKEST Cloudy pale wash at left edge

STRONGEST Dry-brush streaks in vertical lower-centre gap

FLAWS

3 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 3 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: 2 principal ink masses traced (cyan), 7 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 15 edge segments, 53% crisp, 47% 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.
