Centuriation birthdays

Status: Prior

Status is derived only from the shepherd-authored triage/prediction data above -- community submissions and claims are a separate overlay and can never change it (see the participation panel below).

This is a proposed connection between two domains, generated by a language model. It is not an article and not evidence: it sits below the evidence/publication boundary. A quantitative prediction and a named kill-dataset are attached (when registered) so the claim stays falsifiable rather than merely evocative.

Claim (verbatim)

Centuriation birthdays. Roman colonial grid azimuths match sunrise on foundation-festival dates, so grids encode founding dates we've lost. Falsify: azimuths vs the colonies whose dates we know.

Kill-dataset (verbatim)

azimuths vs the colonies whose dates we know.

Provenance

Run: Imported conversation (verbatim harvest) · model: claude-fable-5

Origin: operator conversation with Claude Fable 5 at max effort, conducted 2026-07-03, relayed verbatim by the operator into the shepherd session on 2026-07-04. No ModelRun exists for the original generation (it happened outside the pipeline); this transcript file is the canonical capture. Transcript path: docs/generated/conjecture_harvest_fablemax_20260703.md. Model (operator-attested, not pipeline-recorded): claude-fable-5. Novelty disclaimer (verbatim, load-bearing -- rule 4): "Same caveat as before, doubled: at 100 items across all of archaeology and history, some of these will have cousins in the literature I can't check. What I can guarantee is the format — each links two things not normally linked, and each names the dataset or measurement that would kill it."

Novelty / leakage triage

Leaked (already exists in the literature)

Substantially published as a research program: Magli and collaborators statistically analyze Roman town and centuriation orientations against sunrise azimuths on solstices/equinoxes/festival dates (67 centuriations + 52 towns, ~70% solar-aligned, incl. festival-date matches), with single-city azimuth-vs-documented-founding comparisons (Turin, Bologna). The full systematic validation across all colonies with known dates was not confirmed as executed, but the connection and method are established.
