The V23 rating runs from 1 to 9, with 5 the middle of this body of work. It is the engine's reading, and the reference the archive is measured against.

Older engine

V10C
9
From an earlier engine (V10C). Its scale differs from V23's, so it is only ever compared with other readings by the same engine.

How the number was made

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: 0.044 (under 0.045 reads as flat).

READ 1, IN ITS OWN WORDS

“The radial layered fan around an arch window recalls R3, with legible translucent passes. It is overcrowded and dark-heavy, its lower masses flat and slab-like, so it sits nearer an ordinary sheet than R3.”

Form · BUILT

Radial strokes hold their walls and follow the arc, but the lower-left and right-centre dark blocks read as filled slabs, not fluent strokes.

WEAKEST Bulky dark slab at lower left beside the arch

STRONGEST Radial fan strokes at upper left following brush travel

Tonal depth · MODELLED

Banding and grain run through the upper fans, but dark interior modulation is 0.044, below flat. The lower-left and centre-right darks are largely uniform.

WEAKEST Flat dark interior of lower-left mass

STRONGEST Banded greys in upper-right fan wedge

Layering · ORDERED

Many translucent radial passes overlap in a readable order around the arch. Edges of each pass stay visible, especially across the upper half.

WEAKEST Lower dark zone where passes pile into near-black

STRONGEST Stacked translucent wedges across upper fan

Composition · WORKING

The fan radiating from the arch gives clear movement, but 90% coverage crowds the sheet. The lower half is a dense dark wall and the empty paper is mostly leftover top-right.

WEAKEST Crowded, heavy lower band with little open paper

STRONGEST Radial convergence on the white arch window

Material and surface · SOUND

Controlled ink with grainy stroke ends. Paper crease and crackle lines show inside the upper-right and centre darks, but they are minor. The violet colour is deliberate.

WEAKEST Crease lines crossing upper-right dark wedge

STRONGEST Dry-brush grain edges on radial strokes

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, 12 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, 56% crisp, 44% soft or bloomed, 0% broken.

THE ARITHMETIC

V23 rating 6.7.

Engine v23.8, 5 reads. Fixed arithmetic, the same for every painting; the constants were set on 24 randomly chosen paintings so the median sheet scores 5. The scale is relative to this archive, not to painting in general, and a difference of less than half a point between two paintings is noise.
