Old paper at the desert's edge

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)

Every sheet in a medieval Timbuktu book crossed the Sahara on a camel. Italian watermarks give each sheet a birth date; colophons give the book's completion date; the difference between them is the paper's age-at-use — a direct gauge of trans-Saharan supply-chain speed and inventory depth that no chronicle or customs register records. This conjecture claims the earliest layer shows long lags (decades: paper arrived irregularly and was hoarded, resold, and used late) and that the lag contracts century by century as the trade thickened — the derivative of the lag curve IS the intensification rate of the trans-Saharan book economy. The merchants' logistics are recoverable from their stationery. If it holds, the maturation of the Saharan paper trade can be dated from the books themselves, and any watermark-based dating of Sahel manuscripts must build in a large, era-dependent correction.

Prediction clause (verbatim)

Primary clause: among vHMML-digitized Sahel manuscripts having both a legible watermark match and a colophon date, the median watermark-to-colophon lag declines monotonically across century cohorts, with the earliest cohort's median at 20 years or more and the latest pre-1900 cohort's at 10 years or fewer, significant under a trend test. Killed if the lag is flat, or short from the very beginning — a fast, liquid paper market all along.

Kill-dataset (verbatim)

vHMML African holdings — watermark and colophon evidence in the digitized Timbuktu/Sahel collections.

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

Watermark identification is an established dating strategy for Sahel manuscripts and the Italian provenance of the paper via trans-Saharan trade is well studied (including mill-level identification for Borno and Hausaland corpora). Using the watermark-to-colophon lag as a supply-chain and inventory-depth metric with a contracting-lag prediction was not located.
