The Oracle

What the archive notices.

Every painting is dated, its materials recorded and its surface measured. The Oracle reads all of it at once and looks for patterns that hold across the whole year. 354 have held up so far: 229 from the run drawn here, and 125 from a second, separate search of the same records.

What the Oracle is.

Plain statistics in Python, with no AI and no opinions. It puts everything recorded about the paintings and the days they were made into one table, tests every possible connection, and keeps only what survives strict checks against chance and against time. It does not know what a good painting is; it only reports what holds. Latest run: 2026.10.26.

ONE RUN

From records to findings.

Every number below is from the latest run. A finding has to pass every stage; most do not.

2 ONE TABLE402 paintings

One row per painting, 361 columns. The 316 days of the year join each painting through the 3, 7 and 14 days before it was made.

3 TEST14,140 tests
  • Associations every predictor against every outcome, raw, within one paper, within one batch
  • Time trends trend, change point, floor and ceiling across the year
  • Batches paintings photographed on the same day compared as a group
  • Prediction can anything forecast a rating at all, tested on held-back works
  • Outliers paintings far from what their circumstances predict
  • Streams where the two rating systems overlap, kept apart
4 GRADE229 signals
229Signal: survives correction for the 14,140 tests run (false discovery rate under 5%) and the effect is real in size (rank correlation 0.20 or more)
1,484Lead: suggestive, worth watching, not claimed
12,427Everything else: noise, discarded
THE PLACEBO0 vs 16.0

The Oracle assumes nothing about any source, the sky included: the moon and planets are tested like the weather. To check itself it also runs a placebo, the same 119 sky positions with their dates shifted half a year, so they are linked to nothing. By chance about 16.0 of its tests should pass as signals; 0 did, inside the margin the Oracle allows. Had more passed, the signal threshold would have been halved for the whole run.

TIME HELD CONSTANT30 days

A pattern only counts if it still holds between paintings dated within the same 30 days, keeping at least half its strength. Otherwise it is just the year changing.

BATCHES ARE ONE UNIT49 photo days

Paintings photographed the same day share their day. Anything shared by a batch is tested batch against batch, so one prolific day cannot count as twenty pieces of evidence.

RATINGS ARE OUTCOMESnever inputs

An engine's reading can be explained, never used to explain. Only measured facts and recorded circumstances may predict.

The Oracle runs again whenever the archive grows. A finding that fades on new paintings is marked fading; one that holds on paintings registered after it was found is marked confirmed. How each painting was measured is on the Method page.

1

What it found.

The clearest pattern first, then how each quality moved, then every pattern at once.

2

How sure it is.

How close each of the engine's calls was, whether its two versions agree, and how every finding has held from one run of the Oracle to the next.

3

What it was asked.

Statements about the work, tested against the whole archive, each with its verdict and where it stood in every earlier run.

4

The sky.

The Oracle rules nothing out in advance, so the moon and planets are tested like the weather. The year as the sky saw it is drawn in chapter 1; here is what came of the test.
