Forty days holds, Rome floats

Status: Already answered

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)

Indulgences — remissions of penance measured in days and years — famously inflated across the later Middle Ages. The conjecture is that the inflation had exactly one source: canon law capped each bishop's grant at forty days, and that cap held, so the modal episcopal indulgence stayed flat for two and a half centuries while all growth came from papal grants and from stacking many bishops' forty-day grants onto one shrine. The system thus behaved like a currency with one disciplined provincial mint and one unconstrained central one. If it holds, indulgence inflation was not a diffuse devaluation of penance but a measurable institutional asymmetry, and the totals advertised at any shrine decompose cleanly into a fixed local coin and a floating Roman one.

Prediction clause (verbatim)

Primary clause: in calendared episcopal and papal registers 1250-1500, the modal single episcopal grant remains forty days throughout (a flat series), while the median papal grant grows with a doubling time of sixty years or less. Secondary: advertised shrine totals grow primarily through the count of stacked grants, not the size of any episcopal grant.

Kill-dataset (verbatim)

The Calendar of Entries in the Papal Registers relating to Great Britain and Ireland (Bliss et al.) and printed English episcopal registers (Canterbury and York Society volumes).

Novelty / leakage triage

already answered in the literature

The institutional asymmetry is published: Lateran IV capped episcopal grants at forty days, historians of indulgences (Paulus; Swanson) document that the episcopal cap held for centuries while growth came from papal grants and the stacking of multiple episcopal forties on one shrine. The doubling-time fit is new, but the specific claim is standard indulgence historiography.
