The kings wrote only in stone
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).
Claim (verbatim)
Before the Timbuktu chronicles of the seventeenth century, the earliest securely dated written record of the Middle Niger and its Saharan approaches is not on paper but on stone: the royal funerary stelae of Gao-Saney and the grave and rock inscriptions of Essuk-Tadmakka and Bentyia/Kukiya, the corpus assembled by Paulo de Moraes Farias (Arabic Medieval Inscriptions from the Republic of Mali, 2003) after Sauvaget's study of the Gao royal epitaphs. Some Gao stelae are imported marble, cut and inscribed in the Iberian workshops of Almería and carried across the desert — an object whose very existence proves a literate court commissioning texts abroad in the twelfth century. The mechanism is substrate triage under a hostile climate: Sahelian paper is mortal (termite, Harmattan, damp) and must be recopied or is lost, but cut stone persists, so for the earliest centuries the epigraphic record is not a supplement to the manuscript record — it is very nearly the whole surviving written record, and it drastically undercounts production, because only the monumental and lapidary genres had a survival substrate. Prediction: among all written items from the Middle Niger and its Saharan edge that are securely datable before 1450 by an internal date or archaeological context, at least nine in ten will be inscriptions on stone rather than manuscripts on paper or parchment, and no in-situ Malian paper manuscript will be securely datable before circa 1400 (primary clause: the nine-in-ten epigraphic share of pre-1450 datable writing; the verdict follows it). Kill: P. F. de Moraes Farias, Arabic Medieval Inscriptions from the Republic of Mali (British Academy/Oxford, 2003), with Jean Sauvaget, 'Les épitaphes royales de Gao' (Bulletin de l'IFAN, 1950), counted against the earliest securely dated paper manuscripts recorded in the AMMS and SAVAMA-DCI Timbuktu inventories.

Provenance
Run: Fresh agent generation · model: claude-fable-5
Fresh blind generation by claude-fable-5, 2026-07-17, Sub-Saharan Africa wave 2, weighted by inferred textual production rather than survival, cataloguing, or digitization; every item grounded in real works, authors, chronicles, catalogues, and testimonia and in the real evidence of loss (colonial capture, single-copy transmission, translation-only corpora, Ajami catalogue-invisibility, substrate attrition, and manuscript populations inferred rather than counted), with no fabricated citations, and deliberately disjoint from the 2026-07-10 w16 Africa wave and the 2026-07-16 Africa/Americas wave. Nine candidates were dropped for duplication or a weak kill: the Kilwa Chronicle double-transmission (coin-audit already posed in breadth-africa-americas), the Ahmad Gragn fire age-profile and the Tarikh al-Fattash forged-layer (both already posed there), the Bamum/Njoya script life-cycle (already posed there), the generic Qasr Ibrim genre-proportion and a second Nubia item (w16 Nubia cluster), the Kano Chronicle stratigraphy (folded to avoid a third late-single-witness chronicle), a Futa Jallon Fula Ajami item (dropped to avoid Ajami over-weighting), and a Cape Arabic-Afrikaans item (dropped as too late for the premodern brief).
Novelty / leakage triage
anticipated in the literature — this exact test has never been run
Moraes Farias' 2003 corpus is the standard edition of the Gao-Saney, Essuk-Tadmakka and Bentyia inscriptions, and the observation that the earliest securely dated writing of the Middle Niger is lapidary rather than on paper — including the imported Almería-marble stelae — is his and Sauvaget's published ground. But the primary clause is a quantified census: that at least nine in ten of all pre-1450 securely datable written items are inscriptions on stone. That epigraphic-share proportion has never been computed against an enumerated early paper corpus, and the secure dating of the earliest in-situ Malian paper manuscripts is itself unsettled rather than fixed at c.1400. The materials and the qualitative claim are in print; the 90% count is not.
