Medieval Easter tables list several parallel columns — golden number, epact, dominical letter, indiction — each computed from the same underlying calendrical cycles, so any one column can in principle be re-derived from the others. That mutual derivability is exactly the structure…

One Thousand and One Conjectures
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.
1,053 posed — and counting · measured against the literature (1001 authoritative verdicts): 95 already answered · 843 anticipated — never tested · 50 no prior located · 0 provisional · 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, 849 anticipated but never tested, 52 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.
The conjectures are a public preview of a much larger inference project, coming shortly.

What the tags mean
- 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
- 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
- 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

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…
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…
This joins the Dresden Codex — the finest surviving Maya astronomical manuscript — to the mathematics of best rational approximation. The codex's Venus table tracks the planet with a canonical 584-day period, but the true synodic period is close to 583.92 days,…
Al-Sufi's Book of Fixed Stars transmits each constellation in two mirror parities — as seen in the sky and as on the celestial globe — and copies differ in how the pairing survives. Painters copy their exemplar's pictures, so parity should be…
The earliest medieval annals are laconic year-entries, and many survive physically attached to Easter tables — the computistical grids monks kept for finding the date of the feast. The conjecture makes the attachment causal and testable: annal-keeping began as marginal annotation of…
Liturgical books wore out, but this conjecture claims their replacement was scheduled rather than merely occasioned: because service books traveled with computus material whose Easter tables expire on 19-year and 532-year cycles, houses recopied their choir books when their tables ran out,…
The liturgical year is two interlocking gear trains — the fixed saints' calendar and the movable Easter cycle — and occasionally they jam spectacularly, as when the Annunciation falls in Holy Week. This conjecture claims the written genre that governs such conflicts,…
Byzantium wrote military manuals — the taktika and strategika — for a thematic citizen army run by generals called strategoi. This conjecture says the manual died with the payroll: new witnesses of military manuals track the administrative life of the thematic armies,…
Greek astronomy — Ptolemy and his commentators — survives in copies made at very uneven intervals. This conjecture says the sky set the schedule: new witnesses of the astronomical corpus cluster in the decade after spectacular, chronicle-attested celestial events, because a comet…
In the Palaiologan period, Greek scholars adapted Persian and Islamic astronomical tables — a famous east-to-west transfer. This conjecture says the transfer moved in diplomatic luggage: each Greek adaptation clusters within a generation after a documented Byzantine embassy to or from the…
Byzantium preserved small treatises on land surveying and fiscal arithmetic — unglamorous texts with an unexplained copying rhythm. This conjecture says the state's tax cycle set that rhythm: new witnesses cluster around documented cadastral campaigns, the great re-measurements attested by surges of…
Greek medical compendia — Galenic handbooks, hospital recipe books — were copied in bursts. This conjecture says the bursts ride hospital endowments: new medical witnesses cluster in the decades after the foundation or refoundation of endowed xenones, most visibly the Pantokrator hospital…
Recopying frequency should be set by consultation frequency: a text checked constantly wears out and is replaced on a shorter clock than a text recited from memory or shelved for prestige. Jyotiṣa — the astral-science literature used for calendars, horoscopes, and the…
Every locality in pre-print South Asia needed a fresh calendrical almanac every year, produced by the thousands for immediate use — plausibly the highest-volume written genre of the subcontinent. Yet consumables do not enter archives: an expired pañcāṅga is waste palm-leaf, while…
Annotation is costly attention, and readers spend it where error hurts: a wrong drug dose or a wrongly timed rite has consequences that a wrong poetic reading does not. Marginalia and correction density should therefore rank genres by practical stakes — medicine…
The zero digit is celebrated as a triumph of Indian mathematics and astronomy, yet the earliest securely dated zero symbols known anywhere survive in seventh-century Southeast Asian inscriptions, including the Khmer stone conventionally cited as bearing a śaka date of 605 (683…
The Ethiopian computus (Baḥrä ḥassab) fixes Easter through tables written in Geʽez numerals, themselves derived from Greek letters. If scribes actually recomputed the tables, copying errors would be caught and residual errors would be arithmetic — off by one within a cycle;…
The most multilingual genre on the Silk Road was not scripture but divination: dice oracles and omen manuals exist in Old Turkic (the Irk Bitig), in Tibetan, and in Chinese, with recognizably shared mechanics. Join genre economics to translation history: divination is…
The physical Maya codices are Postclassic objects, but astronomical tables must anchor themselves to absolute dates, and anchors fossilize: a copied table drags its original entry dates along with it, patched by correction increments rather than recomputed from scratch. So the distribution…
An eclipse-warning table of the sophistication preserved in the Dresden Codex cannot be built from one generation of skywatching: fixing long lunar cycle constants to the precision the table embodies structurally requires observational records spanning centuries. That requirement is an existence proof…
An astronomical table carries a radix — a set of starting positions computed for a chosen epoch date, the zero point from which all its numbers count. The surprising connection is that radix dates are political artifacts, not scientific ones: they cluster…
Sexagesimal digits were written in Arabic abjad letter-numerals, in Hindu-Arabic ciphers, and in various Latin conventions, and each system has its own characteristic confusions — which letter melts into which when a diacritic drops, which cipher flips into which under a tired…
A copied astronomical table inherits every error of its exemplar; a recomputed table refreshes them. Whether a given copy was recomputed or merely transcribed is usually treated as scribal temperament, but the surprising connection is that it is infrastructure: recomputation requires a…
An incipit — the opening words by which a medieval text was cited, catalogued, and sold — behaves like a fossilizing tag, but not all genres fossilize at the same rate. The surprising connection is that astronomical incipits mutate far more slowly…
The great medical handbooks were repeatedly abridged into epitomes, and the epitomes were then stuffed with new matter — this much is familiar. The surprising connection is that the process is a regular two-phase pulse with a stable ratio: first-generation epitomes cut…
Middle English medical writing is routinely described as translated 'from the Latin tradition', as if the whole Latin corpus fed it. The surprising connection is that the vernacular tapped almost exclusively the short-text layer — epitomes, compendia, and extracts — rather than…
The Almagest, the central book of ancient astronomy, rarely travels alone in its manuscripts. The surprising connection is that each translation version travels with its own characteristic convoy of satellite texts — introductions, canons, star-lists — stable enough that a codex's translation…
The standard picture has Hindu-Arabic numerals entering Latin Europe through algorism treatises — books that explain the new arithmetic. The surprising connection is that the zero sign appears earlier and more consistently in Latin astronomical TABLES than in Latin arithmetical texts: the…
Mappae mundi look like pictures copied from pictures, and their genealogies are usually drawn accordingly. The surprising connection is that their place-name errors are textual, not graphic: omissions cluster in runs of names that are adjacent in written geographies but scattered on…
Copyists of world maps worked outward from the ideologically loaded centre, and their attention decayed with radius. The surprising connection is that copying fidelity on mappae mundi is therefore a radial function: error and omission density rises with distance from the map's…
Astrolabe retes carry engraved star names, and those names contain errors. The surprising connection is that the errors match the copyist errors of specific manuscript star-list recensions: engravers worked from written lists at the bench, not from other instruments or from the…
Medieval sundials carry engraved hour-lines and hour labels, and computus manuals — the church's timekeeping textbooks — supplied the vocabulary. The surprising connection is that dial epigraphy tracks textbook succession: when a new computus text achieves dominance in a region's schools, the…
The documentary horoscopes preserved on Greek papyri were computed from astronomical tables, and we can now recompute which ones. The surprising connection is that provincial practitioners used systematically OBSOLETE tables — one to two parameter-generations behind the best contemporary theory — with…
In Greco-Egyptian astronomical papyri, prose and numbers did not switch languages together. The surprising connection is that the tabular matter is the conservative organ: layouts, notational habits, and month-name treatments of the Egyptian (Demotic) tradition persist in tables for generations after the…
Pharmacological recipe collections grew by accretion as owners added what they acquired — this is agreed. The surprising connection is positional: the shared ancestral core of a collection sits at the HEAD, while witness-specific additions cluster at the tail and margins, because…
Our canon of ancient medicine is defined by the great treatises the medieval codex tradition chose to preserve. The surprising connection is that the ground-level papyrus record is dominated by a different textual form entirely: catechistic question-and-answer texts, definition lists, and short…
Provençal and Iberian Hebrew astronomical tables and neighbouring Latin tables drew on the same Andalusi Arabic heritage. The surprising connection is that the Hebrew line functioned as a parameter refrigerator: it preserved Andalusi parameter vintages in working circulation for a century or…
The Toledan Tables were the most copied astronomical dataset of the Latin twelfth and thirteenth centuries, and their witnesses contain identifiable corrupt entries. The surprising connection is that these corruptions form geographic clades: bundles of shared errors mark descent from common exemplars,…
Translation between the scientific languages was not one flow but a ladder of genre-specific speeds. The surprising connection is the ordering: calendrical and computus material crossed a language frontier within roughly a generation, practical table canons within about two, and theoretical astronomy…
A mappa mundi has two inheritable layers: the drawn and written content, and the construction geometry laid down before any ink — compass-hole centres, ruled circles, division angles. The surprising connection is that these layers travel separately: physical workshop templates passed between…
The precision of a copied astronomical table was set not by science but by carpentry: the ruled grid of the page. When a scribe copied a table into a grid ruled for fewer or narrower columns than his exemplar used, the final…
Astrolabe plates and portable dials are engraved for specific latitudes, and it is natural to assume those are the latitudes of the cities where the instruments were made and used. The surprising connection is that they are BOOK latitudes: plate values cluster…
Some scientific content circulated in both prose and mnemonic verse — versified computus, versified algorism, versified regimen. The surprising connection is that the verse versions systematically out-diffused their prose sources into regions of thin book culture, so the verse-to-prose witness ratio of…
The twelfth-century Sicilian translations of Greek astronomy directly from the Greek were textually superior to their Arabic-Latin rivals, yet barely circulated — the fact is known, the shape of their survival is not. The surprising connection is that where the Greek-Latin versions…
A zij — the astronomical handbook built around tables — is modular: syzygy and eclipse tables, planetary equations, a star catalogue, geographical tables. The surprising connection is that the modules cross language frontiers in a canonical order, repeated at every frontier: eclipse…
Medieval books were sold, shelved, inventoried, and censored by their first lines. The surprising connection is that alchemical texts exploited this: they circulated under medical-looking incipits — openings promising waters, oils, and the conservation of the body — at rates far exceeding…
Distances cut into itinerary stones and painted into map legends ought to be independent measurements of the world. The surprising connection is that they share scribal corruptions with the written itinerary tradition: numeral errors born on papyrus and parchment were carved into…
Medieval star catalogues rarely re-observed the sky; they updated Ptolemy's longitudes by adding a precession constant, since adding a constant is an afternoon's work and re-observing a thousand stars is a career. The surprising connection is that the added increments form a…
The uroscopy wheel — the circular diagram of graded flask colors that is medieval medicine's most recognizable image — normally appears embedded in a treatise, and editors assume image and text descended together. The surprising connection is that the wheel travels on…
