Zero books from the Basin

Cross-period Dated c. 1400 CE – 1800 CE Americas

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 conjecture imagined by a language model — drawn from its trained weights and held to falsifiability, novelty, and plausibility, not to any one method: it may join two or more fields, or none. 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 Mexica state was a paper state — tribute rolls, ritual books, annals — and its own historiography records the first burning: under Itzcoatl, says the tradition set down by Sahagun's Nahua informants, the lords destroyed the old books so that the people would not know. The conquest finished the work at the center. The Glass-Robertson Census of Native Middle American Pictorial Manuscripts catalogues over four hundred documents of the native pictorial tradition, and read as a survival table it is brutal: the certainly pre-conquest pieces are a rounding error, and none is securely from the Basin of Mexico — the Borgia group belongs to the Puebla-Tlaxcala-Mixteca sphere, the Maya books to Yucatan, and the Codex Borbonicus stands as the lone disputed Basin candidate — while the colonial hundreds show the craft surviving by re-tooling itself for courts, tribute disputes, and friars. Total archive loss at the imperial center, production continuing everywhere under new patronage: that is the shape of the census. Prediction: classified against the Glass-Robertson census, documents judged wholly pre-conquest will be under 4% of entries; none will carry a secure Basin-of-Mexico provenience, Borbonicus remaining the single disputed case; and native-tradition pictorials produced under colonial rule will exceed 85% of entries (primary clause: zero securely pre-conquest documents of Basin-of-Mexico provenience; the verdict follows it). Kill: John B. Glass with Donald Robertson, A Census of Native Middle American Pictorial Manuscripts, in Handbook of Middle American Indians, vol. 14 (1975) — entry-level dating and provenience classifications; the computation is three counts over the census entries.

How this item is catalogued

Catalogue tags are curatorial metadata that make the conjecture findable. They are not findings, not a novelty verdict, and naming a source family is not a promise that the data exist or are accessible. Each dimension below says whether it was assigned, reviewed with none applying, uncertain, or not yet reviewed, and who recorded it.

Place & era tags — Assigned: Americas; Cross-period Tagged by Claude (Opus 4.8)
Dating — Phenomenon: Dated c. 1400 CE – 1800 CE Mexica/Nahua pictorial manuscript tradition: Itzcoatl's book-burning (r.1427-1440) through conquest (1519-21) and continued colonial-era native pictorial production; Glass-Robertson 1975 census is the instrument. Tagged by claude-sonnet-5 + claude-fable-5 (gate)
Subject — Assigned: Texts, scribes & transmission genre-level survival census of Mexica pictorial manuscripts Tagged by claude-sonnet-5
Finer subject topic — Reviewed — none applies: No listed Atlas subject page is squarely about Mesoamerican pictorial manuscripts. Tagged by claude-opus-5 draft (requested max effort) adjudicated by claude-fable-5-1 driver, lane 1da5; runtime not independently attested
Claim level — Assigned: Record claim The prediction is the dating and provenience profile of a census of native pictorial manuscripts: survival of a book class after destruction at the centre. Tagged by claude-opus-5 draft (requested max effort) adjudicated by claude-fable-5-1 driver, lane 1da5; runtime not independently attested
Method — Reviewed — none applies: Three counts over census entries; no formal apparatus. Tagged by claude-opus-5 draft (requested max effort) adjudicated by claude-fable-5-1 driver, lane 1da5; runtime not independently attested
Evidence source — Assigned: Mesoamerican codices; Published editions Kill test counts entries of the Glass-Robertson census of native Middle American pictorial manuscripts by dating and provenience classification.

Provenance

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

Fresh blind generation by claude-fable-5, 2026-07-16, breadth wave: Sub-Saharan Africa + pre-Columbian Americas, weighted by inferred production and above all by loss; every item grounded in real works, authors, codices, catalogues, and testimonia, including the real evidence of destruction, dispersal, and undecipherability; no fabricated citations.

Novelty / leakage triage

already answered in the literature

The census-level result is published: the Glass-Robertson survey itself states that only about sixteen of its 400-plus manuscripts are considered preconquest, and Boone states that no pre-conquest book securely survives from the Basin of Mexico (Borbonicus the disputed case), the craft surviving in colonial hundreds. The conjecture's three counts re-derive the census's own published statistics.
