Eustathius is the ark

Status: Anticipated in print · 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 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.
“Anticipated in print” means the direction of this claim already appears in scholarship, while this exact test has never been run — it records prior art, not proof; nothing here counts as supported or falsified until a registered resolution says so.

Claim (verbatim)

Eustathius of Thessalonica compiled his twelfth-century Parekbolai on the Odyssey from sources richer than what our scholia manuscripts now transmit — he quarries his ancients continuously. Because the Odyssey's direct scholia channel is the damaged one, with thin carriers and no apparatus-codex, Eustathius functions for this poem less as a digest of what we have than as the sole surviving refraction of what we lost. The claim makes that proportion measurable: a substantial fraction of his line-anchored exegesis on the early books has no parallel in any extant Odyssey scholium — ancient material that survived nowhere else, trapped in his prose like insects in amber. If true, Eustathius is not a convenience for Odyssey philology but a primary witness, and the loss-rate of the Odyssey's ancient commentary can be estimated from his unique notices the way lost-book counts are estimated from single-copy survivals in medieval library catalogues.

Prediction clause (verbatim)

Primary clause: for Odyssey books 1-2, at least one-fifth of Eustathius' discrete exegetical notes lack any parallel in the extant scholia vetera as edited by Pontani. The bar is deliberately low; the true fraction is wagered to be higher.

Kill-dataset (verbatim)

Eric Cullhed's edition of Eustathius' commentary on the Odyssey, volume 1 (Uppsala 2016), whose apparatus of parallels can be cross-indexed against Pontani's Scholia Graeca in Odysseam.

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 scholarship. Kills and prior scholarship are credited here, by name, as they come in.

Provenance

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

Fresh blind generation by claude-fable-5 on 2026-07-21 for the Odyssey wave (run_key 'odyssey'): posed from model weights only, with no repository reads, no searches, and no web access; every named papyrus, manuscript, edition, catalogue, and dataset is cited from memory in good faith with no fabricated references.

Novelty / leakage triage

anticipated in the literature — this exact test has never been run

That Eustathius preserves ancient exegesis lost from the direct scholia channel is consensus, stated by his editors. The measurable fraction — at least one-fifth of his discrete notes on books 1-2 without parallel in the extant scholia vetera, checkable against Cullhed's parallels apparatus crossed with Pontani — is an unrun measurement that would put a number on the Odyssey channel's loss rate. Caution: 'discrete exegetical note' needs a pre-pinned segmentation rule; Cullhed's apparatus conventions should define it.
