Ars Inquirendi

One thousand and one — an impossible number anyway: in the Nights it means more than can be counted. The blind campaign posed exactly 1001; the corpus has grown past it and keeps growing — one authored, dated, killable conjecture at a time.

Two storytellers on a manuscript flying carpet

1,107 posed — and counting · measured against the literature (1001 authoritative verdicts): 95 already answered · 843 anticipated — never tested · 50 no prior located · 15 resolved (6 supported / 4 killed)

Falsifiable conjectures about the pre-print world. The founding thousand and one were generated blind by Fable, a frontier AI, then judged, one dated literature-search each: 95 already answered by the literature, 843 anticipated but never tested, 50 with no prior located — verdicts independently audited by a second model (45-verdict sample; none overturned). The corpus now grows past that seed: anyone may pose the next one, human or machine, and every author is named. Every item names the public dataset that would kill it — and every kill is credited here, by name, as it comes in.

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-art 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 Yule process — the preferential-attachment mathematics behind power laws in citations, city sizes, and web links — is here applied to the medieval book world. A text gets copied because copies of it exist to be found and read: every extant…

The Tabula Peutingeriana, the famous medieval copy of a Roman route map, was almost certainly compiled from multiple earlier itineraries rather than drawn from any single survey. Each source itinerary would carry its own error habits — its own units, rounding conventions,…

An abecedarium — a written-out sequence of an alphabet in its canonical order — is copied and taught from teacher to pupil down the generations, and each retransmission risks small changes to the order: a transposition, an inserted letter, a dropped one.…

Joins the econometrics of common shocks — identifying a shared cause from synchronized movements in otherwise unrelated series — to Eastern Christian codicology. Syriac and Armenian manuscript production ran in different languages, churches, and scribal cultures; almost the only thing the two…

Joins the chronology of Thomas Aquinas's writing career to the arrival curve of the new Greek-Latin Aristotle: early on, Aquinas met much of Aristotle through florilegia, commentary lemmata, and older versions, quoting at second hand; as William of Moerbeke's literal translations and…

in the scholastic classroom the objection-side authorities functioned as a memorized bank of classic difficulties — an objection had to be recognizable to master and audience to carry disputational force, so the same hard sayings of Augustine, Aristotle, and Jerome were recycled…

When binders needed stiffening material they cannibalised old manuscripts, cutting them into the waste fragments now recovered from bindings. The naive model treats this as physical wear-out — books used until they fell apart — which would produce a smooth aging hazard.…

Guido of Arezzo's staff notation — the 11th-century invention that fixed pitches on lines rather than leaving them to memory-jogging squiggles — is here treated as an error-correcting code, and its effect on transmission is claimed to be discontinuous rather than gradual.…

Radiocarbon dating works because decay happens at a constant rate; the conjecture is that manuscript copying does too. Scribes make errors, and within a single scriptorium — same training, same exemplars, same working conditions — the rate of new errors introduced per…

Stemmatics — reconstructing the family tree of manuscripts from shared copying errors — is here fused with computational astronomy. A dated horoscope is a calculation: the astrologer looked up planetary positions in one specific physical copy of a set of astronomical tables…

Information theory meets Homer: the stock formulas of oral epic — the swift-footed heroes and wine-dark seas — are here interpreted as redundancy bits, the padding a noisy channel needs to protect its payload. In transmission over fallible human memory, the hard-to-recover…

Two transmission technologies for Sanskrit ran side by side for centuries: the mnemonic machinery of Vedic recitation — interlocking recitation modes and error-checking permutations built to preserve the Rigveda syllable-perfect — and ordinary manuscript copying, which carried texts like the Mahābhārata. Philologists…

Chinese court astronomers recorded celestial omens for two millennia, but they worked for a state in which comets and eclipses bore directly on the Mandate of Heaven — so the record was politically sensitive by construction. Korean, Japanese, and Arabic astronomers watched…

Rongorongo, the undeciphered glyph system of Easter Island, does not have to be read to be classified: its sequence statistics can be compared against the signatures of known genres. Recitation genealogies and chants — well attested in Polynesian tradition — have a…

This joins medieval fiscal instruments to information theory. An Exchequer tally was a wooden stick notched with a debt's value and then split lengthwise, creditor and debtor each keeping half; the split's matching grain already authenticated the pair. The conjecture claims the…

This joins Mesopotamian glyptic art to the economics of security. A cylinder seal was its holder's signature, and like any signature it invited forgery; the defence was engraving complexity, since an intricate scene costs a forger far more to copy than a…

This joins the world's oldest accounting technology to modern medical imaging. Before writing, Mesopotamian administrators sealed counting tokens inside clay envelope-bullae and impressed matching marks on the outside: the surface advertised the contents, and breaking the envelope audited the claim. Envelopes that…

Joins capture-recapture ecology to Greek philology: ecologists estimate how many species they have never seen from the ratio of species observed exactly once to species observed exactly twice, and the same arithmetic applies to books. Each surviving witness to a Greek work…

Joins statistical seismology to archival formation processes: an administrative archive, the claim runs, forms like an earthquake sequence. A main shock — a reform, a new institution, a royal accession — sets off a burst of documentation, and what follows obeys the…

Joins the cognitive psychology of recall to the stemmatics of oral law. The serial-position curve is among psychology's oldest findings: in reproducing a fixed sequence, people hold the beginning and end best and blur the middle. Iceland's law was exactly such a…

The cutting-stock problem of operations research — how to cut standard stock into pieces with minimal waste — meets codicology. This conjecture holds that parchment page sizes were not aesthetic free choices but near-optimal cuts of animal skins: a skin is a…

Technology-diffusion theory describes adoption lags that collapse as a transmission channel routinizes; this conjecture measures that lag curve in Timbuktu codicology. Between 1400 and 1600 the Sahara's intellectual bandwidth tripled: pilgrimage traffic, commercial caravan routes, and the rise of Sankore scholarship turned…

Capture-recapture statistics estimate a population's size from the overlap between independent samples — tag fish, resample, count the recaptures. This conjecture treats the great Sanskrit subhashita anthologies — the Subhashitaratnakosha, Saduktikarnamrita, and Sharngadharapaddhati — as quasi-independent samples drawn from a floating ocean…

Packet-switched content distribution splits a file into chunks that travel independently and reassemble at the destination; the medieval university book trade did the same with texts. Under the pecia system, stationers chunked an exemplar into pieces rented out separately, so a single…

Joins the manuscript history of the Thousand and One Nights (the lean Galland-manuscript core versus the swollen Egyptian recension) to the mechanics of frame-tale carpentry: insertion is cheapest at the frame's outermost seam, where Shahrazad's nightly break gives any compiler a licensed…

Connects the disputatio's argumentative architecture to the material sources of quotation: the objections a scholastic author stages are the tradition's stock counter-texts, harvested from commonplace collections and classroom memory, whereas the constructive respondeo forces the author back to the authority's actual wording…

Connects the rise of Garshuni (Arabic language in Syriac script) to the performance hierarchy of Christian genres: chanted liturgy is text welded to trained bodies — cantors' eyes and memories were schooled on Syriac pages — while theology, medicine, and tales served…

Joins the Kaicheng Stone Classics of 837 — the Tang state's carving of the Confucian canon on steles at the imperial academy — to the variance structure of the Dunhuang classical manuscripts: once an examination state publishes a physical reference text, teachers…

Joins Sanskrit metrics to stemmatics as a dating instrument: the epic shloka admits licensed variations (the vipula forms) whose frequencies drifted historically toward the stricter classical norm, and an interpolator cannot help writing the verse rhythm of his own training. Passages rejected…

Connects the world's longest translation chain — Kalila and Dimna from Sanskrit through Middle Persian and Arabic into Syriac, Greek, Hebrew, Latin, and Castilian — to a two-speed model of what a book is to its transmitters: chapters are detachable assets that…

Connects frame-tale morphology to accretion dynamics: some frames advertise a number — seven sages telling set tales, ten narrators times ten days — and some advertise only survival-by-storytelling, an open valve. A counted frame makes every insertion a visible breach of contract…
