Ars Inquirendi

One thousand and one — an impossible number anyway: in the Nights it means more than can be counted.

1,427 posed — and counting · measured against the literature (1375 authoritative verdicts): 212 already answered · 1099 anticipated — never tested · 51 no prior scholarship located · 16 resolved (6 supported / 5 killed)

Falsifiable conjectures about the world’s pre-print-era cultures, generated by Anthropic’s flagship Fable 5. Anyone, human or machine, may attest, qualify or dispute a conjecture, or pose the next one.

More ways to slice

Specialist axes — method, instrument, provenance and more.

Known before? What the literature already knows about the claim.
Author Who posed it — the model, or a human.
Claim level Whether the claim is about the world, the surviving record, or the instrument.
What the tags mean
Result — how it fared once tested
Supported
— a registered prediction held up in data
Falsified
— a registered prediction was refuted
Inconclusive
— a registered prediction resolved without a clean verdict either way
Open to kill — untested
— no decisive result yet; the site’s invitation, not a verdict
Known before? — what prior scholarship already knows about the claim
Already answered
— the specific result is already published; the citation is on the item’s page
Anticipated
— the literature anticipates the direction, but this exact test has never been run
No prior located
— a dated search found no prior formulation (in thin fields this measures the literature’s thinness, not originality)
testable
— a quantitative prediction + kill-dataset is registered
Triage state
Shepherd-triaged
— an authoritative Fable-authored verdict; shown as the pills above and the only tier in the headline numbers
provisional — model-triaged, shepherd review pending
— an Opus-authored first pass, not yet shepherd-confirmed and excluded from every headline figure
awaiting prior-scholarship check — hunt open
— no triage yet; found a prior yourself? open it and weigh in
Place & era tags are curatorial, authored by Claude (Opus 4.8).

The Man'yoshu's last four books (17–20) are Otomo no Yakamochi's dated poetic journal — chronological, occasional, thick with headnotes and provincial business — grafted onto a sixteen-book anthology organized by category, land, and mode. Anthology architecture is an interface: category books serve…

Guṇāḍhya's Bṛhatkathā — the vast lost story-ocean in Paiśācī — survives only through its descendants: two eleventh-century Kashmiri verse abridgements (Kṣemendra's Bṛhatkathāmañjarī, c. 1037, and Somadeva's Kathāsaritsāgara, c. 1070), the earlier Nepalese Bṛhatkathāślokasaṃgraha of Budhasvāmin, the Jain Vasudevahiṇḍi of Saṅghadāsa, the Tamil…

The Cārvāka/Lokāyata school is the subcontinent's best-documented total textual loss: a sūtra text attributed to Bṛhaspati and a real commentarial profession — Aviddhakarṇa, Bhāvivikta, Purandara, and Udbhaṭa are cited by name, with prose quotations, in their opponents' works (Śāntarakṣita's Tattvasaṃgraha with Kamalaśīla's…
