The murrain that never reached the library

Status: Anticipated · untested

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)

Parchment is proverbially the expensive bottleneck of the medieval book — a Bible costing a whole flock. The conjecture is that at the aggregate level this is false: book production consumed a trivial share of the skins that slaughter yielded anyway, so parchment supply never constrained output, and the proof is in the shocks — the great livestock plagues, which devastated herds, should leave no dent in book production series, while the human plague, which devastated hands, visibly does. The skin was dear at the retail counter but never scarce in the economy; the binding constraint was always the scribe. If this holds, the standard supply-side story of the parchment-poor Middle Ages breaks, and the price of parchment must be reread as processing markup rather than raw-material scarcity.

Prediction clause (verbatim)

Primary clause (carries the verdict): dated manuscript production totals show no significant decline (nothing beyond 10%) in the five years following documented major livestock panzootics such as the 1310s cattle plague, whereas the five years after 1348 show a drop of at least 25%. Secondary clause: parchment demand implied by production totals is under 5% of estimated regional skin supply in every region-century cell tested.

Kill-dataset (verbatim)

Scriptome production estimates by year-band and region (in-house), with SfarData dated colophon counts as an independent dated series; the kill is a statistical event-study comparing livestock shocks with labour shocks.

Nobody has run this test. The kill-data is named above. If you can run it — or you know the paper that already settles it — claim the kill or submit the prior. Kills and priors are credited here, by name, as they come in.

Provenance

Run: Fresh agent generation · model: claude-fable-5

Composed blind from the model's own knowledge in a zero-tool session and emitted directly as final text.

Novelty / leakage triage

anticipated in the literature — this exact test has never been run

The 1310s-1320s cattle panzootic is well documented (Newfield) and the 'one Bible = a flock' retail framing is a commonplace, but the aggregate-supply inversion—parchment demand <5% of skin supply, so livestock plagues leave no production dent while 1348 drops output >=25%—has not been tested as a comparative event-study.
