Overflow breeds the postill

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 Glossa Ordinaria wrapped the Bible in marginal commentary; the postill was a separate, self-standing commentary that flourished from the thirteenth century. The conjecture: the postill genre was born of page geometry, book by book — where the standard Gloss had already saturated the margins (Psalms, Pauline epistles), no new layer could be squeezed in, so updating exegesis had to secede into its own codex, while lightly glossed books kept absorbing additions in place. Stationers and masters followed the parchment, not the theology. If true, the intensity of separate commentary production per biblical book is predicted by gloss density, a physical variable, and the intellectual map of scholastic exegesis was drafted by mise-en-page.

Prediction clause (verbatim)

Primary clause: across the biblical books, gloss density (words of Gloss per word of biblical text, measured in the Rusch 1480/81 editio princeps as proxy for the mature Gloss) rank-correlates at rho of at least 0.5 with the count of distinct thirteenth-century commentaries per book in Stegmuller. Secondary: the correlation weakens for fourteenth-century commentaries as the postill format becomes default.

Kill-dataset (verbatim)

Stegmuller's Repertorium Biblicum Medii Aevi commentary counts per biblical book, with the facsimile of the Rusch 1480/81 Glossa Ordinaria for density measurement.

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

Smalley, de Hamel and Lesley Smith established the Gloss's mise-en-page and its book-trade standardization, and the postill's emergence as self-standing commentary is well described, but the causal join — per-book gloss density predicting thirteenth-century commentary counts — is un-run.
