The missal lags the chantry

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)

The plenary missal — one volume merging the prayers, readings, and chants that older practice split across sacramentary, lectionary, and gradual — took over Latin Europe between 1000 and 1300, and liturgists explain it by the rise of private masses. This conjecture makes the driver measurable and financial: regional missal adoption follows, with a roughly one-generation lag, the regional wave of endowed private-mass foundations (chantries, anniversaries, altar endowments) recorded in charters, because each endowment created a stand-alone workstation — one priest, one side altar, one book — and the book market consolidated formats to serve it. The missal is the hardware of the anniversary-mass industry. If this holds, dated charter series predict the sacramentary-to-missal ratio in each region's surviving books, tying a liturgical format shift to a documented capital flow.

Prediction clause (verbatim)

Primary clause: across at least six regions, the date at which missals reach half of surviving dated mass-book production trails the date at which the region's charter series shows sustained take-off in private-mass endowments by 20-60 years, preserving rank order across regions; violation of the ordering in more than one region kills the item. Secondary clause: cathedral high-altar books (where staffing stayed collective) remain split-format significantly longer than side-altar and parish books within the same regions.

Kill-dataset (verbatim)

Dated mass-book counts by type from the catalogues of dated manuscripts and the e-codices/Gallica descriptions (public), against endowment-foundation rate series extractable from the published regional charter books (cartulaires and Urkundenbucher) — a lagged rate comparison.

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.

Novelty / leakage triage

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

The driver is already the standard published account: the plenary missal developed out of libelli missae for private masses at secondary altars, replacing the sacramentary by the twelfth century — the item concedes this and only adds a charter-series lag statistic, which is an un-run quantification of the documented mechanism.
