Buried at Thebes, copied at Byzantium
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)
The only Greek alchemical books that survive physically from antiquity survive outside the manuscript tradition altogether. Leiden papyrus X and the Stockholm papyrus - sister books from a single Theban cache of around 300 CE, dispersed through the Anastasi consignments to Leiden and Stockholm in the 1820s-30s - carry roughly two hundred and fifty workshop recipes: alloys, gold- and silver-writing, gem and pearl imitation, purple substitutes. They are the practical stratum of the art, and that stratum has no Byzantine descendants: no medieval Greek manuscript transmits these texts or any recognizable recension of them. The theoretical corpus, meanwhile, survives only by the anthology-copying channel and left no ancient books at all. One art, two disjoint survival modes - burial for the shop-books, copying for the doctrine - with almost no traffic between the channels even at the level of individual recipes, as the apparatus of parallels in Halleux's edition lets us check. The mechanism: a shop-book's value was use, not prestige; it was consumed where it worked, never collected, and could reach us only by the archaeological accident that preserved it, while doctrine, prestigious and teachable, entered the collector's channel and paid the anthology filter's price. Prediction restated: CMAG records zero medieval witnesses of the papyri's texts, and fewer than 20 percent of the papyri's recipes have verbatim-class parallels anywhere in the CAAG corpus.
Prediction clause (verbatim)
Prediction: searching the CMAG census for any medieval manuscript witness of the texts of Leiden papyrus X or the Stockholm papyrus yields zero witnesses (primary clause: the zero-descendant count; the verdict follows it), and under Halleux's apparatus of parallels fewer than 20 percent of the two papyri's recipes show verbatim-class parallels in the CAAG-edited corpus; recipe counts follow Halleux's Bude edition, and the test voids for coverage if that edition's recipe numeration cannot be applied.
Kill-dataset (verbatim)
Kill: CMAG (a negative search over the full eight-volume census) plus Halleux, Les alchimistes grecs t. I (Bude, 1981) with Leemans (1885) and Lagercrantz (1913) - a descendant census and a recipe-parallel share count.

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.

- Dating — Phenomenon
- Dated c. 200 CE – 400 CE Claim's own explicit anchor: the Theban papyrus cache (Leiden X, Stockholm papyrus), 'around 300 CE'; the 1820s-30s Anastasi dispersal to Leiden/Stockholm is a modern acquisition event, not the dated subject. Tagged by claude-sonnet-5 + claude-fable-5 (gate)

- Claim level — Assigned
- Record claim The prediction is zero medieval witnesses of the Theban papyri's texts and a low verbatim-parallel share: two disjoint pre-modern survival channels for one art.

- Channel dissociation The test compares two transmission channels for one art, archaeological burial of shop-books against anthology copying of doctrine, and predicts they carry disjoint content.

Provenance
Run: Fresh agent generation · model: claude-fable-5
Fresh blind generation by claude-fable-5, 2026-07-18, craft-and-technical-knowledge domain: the Graeco-Egyptian alchemical corpus and its Syriac/Arabic penumbra, chosen because it is the pre-print world's best-instrumented lost technical literature - a closed corpus with open, named instruments (CAAG 1887-88 open scans; CMAG 1924-32; Suda On Line; the Theban papyri in Leemans/Lagercrantz/Halleux; Berthelot-Duval CMA II open; Fihrist in Fluegel/Dodge; Kraus 1943 + Sezgin GAS IV) - and because greps showed the core untouched (Zosimos, Marcianus, Stockholm/Leiden papyri, Maria, Cleopatra, Ostanes, Democritus/Bolus, Berthelot, chrysopoeia, Kraus, Jabir/Geber, Hermes/Hermetica: no hits anywhere). Carves and seams, checked wave by wave: lost-in-translation 2026-07-18 owns translation-as-survival (Galen/Hunayn, Hero's Mechanics ord 5, al-Kindi Fihrist book-list survival ord 8, versio-only shares) - no Greek-cliff/Arabic-continuation item here, and the Syriac Zosimos enters only inside the ord-5 alphabet-coverage census whose primary clause is corpus completeness, not translation survival; byzantine-dbbe-pinakes owns Photios, pooled Suda title-survival (its ord 4) and the Pinakes earliest-witness histogram (its ord 9) - witness censuses here run on CMAG, a different instrument, and the Suda serves only as a single-entry book-count yardstick (operation-shape shared with ancient-sound ord 10 on Aristoxenus; new author, new letter-coverage operation, flagged); ancient-sound ord 7 owns burial-vs-copying for music - ord 8 here runs a descendant-census channel split on a different corpus with a different operation; fable-w20 ord 15 owns positional recipe stratigraphy (papyri.info/eVK) and ord 26 owns Latin alchemical incipit camouflage (eTK) - no positional or incipit operations here and Latin alchemy left untouched (w20's 'Mappae' hit is mappae mundi, so the Mappae clavicula remains free for a future recipe-book wave); the Fihrist is a crowded instrument (five prior waves) reused solely as the maqala-10 roster inside a two-catalogue asymmetry join no prior wave runs, flagged. Dropped candidates: Hero/Philon/Ctesibius mechanics (coordination instruction plus lost-in-translation ord 5), Dioscorides alphabetization (byzantine-wave adjacency; Galen owned), Geoponica/lost agronomists and Mappae clavicula/Theophilus (both verified free - reserved as future bodies), Turba philosophorum (translation-survival shape owned). Soft counts (pinax entry total, lexicon entry count, Pliny index-book count, roll length, Syriac letter-book count, Kraus register arithmetic) are kept out of load-bearing primary clauses behind explicit coverage guards; ords 2, 4, 8, 9 rest on HIGH-confidence anchors, ords 1, 5, 6, 10, 11, 12, 13, 14 on MODERATE counts flagged in the report, ord 15 is honestly Kill-not-yet-built.
Novelty / leakage triage
already answered in the literature
Halleux's edition states the isolation outright: the Leiden and Stockholm papyri are archaeological unica with no medieval manuscript tradition - no Byzantine witness transmits their texts - and his edition registers the parallels between the papyri's recipes and the later corpus in its apparatus, so both the zero-descendant clause and the thin parallel share are stated or tabulated in the very Bude volume the conjecture names as its instrument.
