Peter replies himself; asking commits you to nothing. In this country the law says every new king must lay his map over the last one, in smoked glass, so that the old borders show through and nothing is forgotten. It works for a while. At the western point you can still read who owned the river. Go east and the glass thickens. By the far corner the whole kingdom is a single black pane, and the current king rules it with total confidence, issuing decrees about a province he cannot locate. He is quite happy. I poured his tea, and he asked me the way to his own capital. West of the first pane, past the edge of the surveyed world, a few dark drops lead away across the white: a cartographer, leaving on foot, sleeve still dripping.

It explains V23's numbers and may not change them. - **Structure:** broad flat slabs overlapping along one arc, joined into a single fan - **Movement:** rising left to right along the arc, nothing running against it - **Coverage:** ink on about four fifths of the paper - **Tone:** two tonal steps, weighted dark - **Layering:** pale grey passes under dark translucent slabs, readable at left, centre and lower edge - **Edges:** crisp at squared slab ends, soft around lower left, broken at lower right - **Feibai:** none - **Open paper:** pale band wrapping from top left down the margin, along a stepped lower edge - **Colour:** faint warm reddish brown in the lower-left slab - **Chance marks:** spatter at left margin and bottom centre, grey stains at left, round spot lower left - **Frame:** ink runs off top and right; left and bottom stay open A wide fan of black swings up from a sharp point at the left and travels right, slab over slab, until it jams against the top corner. The direction is clear from across a room, and so is the weight: the heaviest ink sits high on the right. The interest lies left of centre, where each flat pass lands over the last and its wall stays visible through the new layer. Half-sized paper softens an edge without losing it, so the order of building stays legible. The faint red in the lower-left slab is paint, and it lifts that corner from its cool grey border. At lower right the strokes thin into dry, streaked ends, the liveliest surface on the sheet. Upper right, the passes stack until their order is gone. Every added layer brings density and takes away information, leaving a squared, stiff block that barely shifts inside. A fold and crumple lines cross it without much harm. The smears and drips in the left margin belong to no form and are simply accidents. An average sheet, then, competently built. It rewards a slow look on the left and shuts that look down on the right. Read and measured ## The rating THE RATING ## T_378, rated 5.3 The combined score, out of 10: V23's reading of the photograph as the read half and V24's twelve tests on the 16-bit file as the measured half, added and divided by 10. The scale is relative to this archive. How each half is made is on the Method page. READ HALF 22.5 V23's rating, 4.5, × 5 + MEASURED HALF 30.6 twelve tests, of 50 → RATING 5.3 53.1 ÷ 10 THE READ HALF, V23 - **Form:** 2.0 · built - **Tonal depth:** 1.0 · thin - **Layering:** 2.0 · legible - **Composition:** 2.0 · working - **Material and surface:** 1.4 · flawed THE MEASURED HALF, V24 - **Mass:** 8.8 of 10 - **Tone:** 7.0 of 14 - **Void:** 8.0 of 8 - **Flow:** 3.6 of 10 - **Balance:** 3.2 of 8 Measured ## How it was measured FROM THE 16-BIT FILE ## What V24 measured. Plain physical facts with no model involved. Across the year they track how the practice changes. On one sheet they cannot say whether a mark is any good. Millimetres read a few percent high, because the photographs are cropped just inside the paper's edge. MASS WIDTH 209 mm The width of the ink mask along its medial axis. DEPTH OF THE DARKS 1.52 Optical density at the 75th percentile of the sheet. LARGEST VOID 114 mm The radius of the largest circle of open paper. DIRECTIONS 0.44 How far the marks align across the sheet. Lower means they run several ways. BALANCE 0.66 Left and right asymmetry of the ink. Lower is more even. THE FILE 4.38 Pixels to the millimetre in the TIFF these were measured from, with the studio light removed. 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](https://peteryuill.art/method). 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. ![T_378] ![T_378, tone-stretched] ![T_378, classed by brightness] 80% of the sheet carries ink TONAL STEPS ## 2 families of tone. Every inked pixel's brightness in 64 bins, smoothed; each circled peak holds at least 4% of the ink. Two or fewer: Tonal depth is held at the bottom rung whatever the model reads. A dense sheet of many translucent passes can count low here, so Layering is left to the reads. Life inside the black: 0.053 (under 0.045 reads as flat). FIVE READS ## Five reads, agreeing on 4 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.

The upper-right dark fuses into one flat field, and creases plus margin stains weaken the surface. An ordinary sheet.” Form · BUILT Broad arc slabs fan from the left point with holding walls and dry-brush ends at the lower right; the upper-right slabs fuse into one bulky block. WEAKEST Bulky dark slab block filling upper right STRONGEST Tapered arc stroke sweeping from left tip Tonal depth · MODELLED The stretched view shows grain and stepped density in the centre and left slabs. Only two tonal steps; in the colour view the upper-right dark reads as a flat surface. WEAKEST Dense near-uniform dark in upper right mass STRONGEST Banded, grained centre slab with brush striations Layering · LEGIBLE Several overlapping slabs can be read at the left and centre edges. On the right, the later dark passes bury the earlier ones, so the order of passes is lost there. WEAKEST Upper-right passes merged into one dark field STRONGEST Translucent slab edges overlapping at left and centre Composition · WORKING A fan-shaped arc carries the eye from left to right. Ink covers 80% of the sheet, so the mass crowds the top and right edges and the leftover paper at bottom left is weakly shaped. WEAKEST Crowded, heavy upper-right mass presses on edges STRONGEST Fan arc rising from left point Material and surface · FLAWED A vertical fold and crumple creases run through the central dark mass. Grey blotches and drips mark the left margin, and a round spot sits inside the lower-left slab. WEAKEST Crease lines and fold through central dark mass STRONGEST Dry-brush trailing ends at lower right FLAWS ## 7 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 7 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. A major flaw holds Material and surface at rung 1.
