One Thousand and One Conjectures

The number of scripts in active use in a region scales with its interaction volume the way species richness scales with island area.

Mother-well spacing follows aquifer drawdown-interference radii — hydraulic property rights fossilized as geometry. Falsify: satellite qanat maps vs aquifer parameters.

Regional ship lengths avoid resonant pitching in local wave spectra: Baltic and Atlantic wreck length distributions should differ exactly as wave climatology predicts. Falsify: wreck dimension databases.

Star compasses arise where winds are variable, wind compasses where trades are steady: navigation systems are optimal solutions to local wind-steadiness statistics. Falsify: system type vs climatological wind constancy across Oceania.

Joins radioactive-decay statistics and firm-survival analysis to monastic geography: manuscript-producing places died at a constant hazard, like unstable isotopes; a scriptorium that had already survived two centuries was no safer in the next century than a fifty-year-old one.

Joins the Byzantine school selection of the tragic triads to the older stratum of anthology culture: teachers selected plays not by dramatic merit but by gnomic yield — the sentences a schoolboy could copy, memorize, and deploy — and that yield had…

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…

in the Syriac schools, logic was not a discipline but a fixed propaedeutic block welded to theological training, so it was copied as a single curricular object for over a millennium. Porphyry's Eisagoge, the Categories, and De interpretatione should move together; the…

across the great translation movements, commentaries crossed the language frontier at far lower rates than base texts — except lemmatized commentaries that embed their base text, which crossed at near-base-text rates. Patrons commissioned usable, self-sufficient objects; a commentary without its base text…

This connects the well-known devaluation of the ijaza into a formality with the rhetoric of the document itself. As real audition decayed into blanket and even to-whom-it-may-concern licenses, the certificate lost evidentiary content; the conjecture is that the parchment compensated. Neither the…

This connects paper-trade standardization with the size distribution of surviving books. Paper left the mill in named full-sheet formats, and books were cut as the full sheet, its half, its quarter, its eighth; a warraq's stock was a ladder, not a continuum.…

This connects the known takeover of the Islamic paper market by European mills with a datable moving boundary in the codicological record. Watermarked Italian paper displaced Oriental laid paper, but not everywhere at once: it should have swept as a front, arriving…

This connects the near-monopoly of one Qurʾanic transmission (Hafs ʿan ʿAsim) in the later manuscript record with imperial book provisioning rather than early canon dynamics. Regional readings, Warsh, Qalun, al-Duri, held substantial shares of the copied record for centuries. The conjecture: the…

This connects art patronage with textual growth in the Persian epic tradition. Shahnama copies vary by thousands of verses, and the variation is usually treated as scribal drift. The conjecture: interpolation was patron-driven. A royal commission was a completeness market, the fullest…

This connects library ecology with the age structure of surviving copies. In high-churn metropolitan book markets, old copies were superseded, sold off, and scrapped: replacement, not catastrophe, is the great killer of early exemplars. Yemen's Zaydi libraries sat in a low-churn ecology,…

The institutional roster of the state translation assembly (yichang) — which included a dedicated zhengzi orthography-rectifier and a bishou receiver — should be legible in the statistics of Sanskrit-name transliteration. A solo translator spells a foreign name as it comes to him…

Taboo observance is a writing-time behavior, but block recutting is a tracing-time behavior — a Yuan workshop recutting a Song edition pastes the old print face-down and cuts what it sees, so the dead dynasty's omitted strokes ride through untouched, while a…

Whether the empire printed or brushed a monumental compilation was decided by intended copies, never by size — blocks are a fixed cost recouped over impressions, so a work wanted in three copies is cheaper brushed however vast it is. The canons,…

The Tripitaka Koreana's 80,000-plus blocks at Haeinsa include later recut replacements among the 13th-century originals, and blocks die two ways: randomly (wood defects, accidents — uniform across the canon) or by use (inking, printing, handling — concentrated where prints were demanded). If…

Which Shahnama episodes got painted is normally explained by narrative salience and patron taste. In commercial production the causality should often run the other way: painting spaces were reserved at ruling time, spread across the planned quires so a buyer flipping the…

That illustrated books survive preferentially is doctrine; the sharper, unestablished claim is that survival and integrity anticorrelate through the dealer's knife. Every painting is a separable asset, so the hazard of dismemberment grows with painting count, and the market leaves a dose-response…

Rubbed-out faces in Persian and Arabic figural manuscripts are usually narrated as diffuse pious attrition accumulating across many readers. If that were so, defacement per manuscript would spread smoothly with use. But if defacement is typically one owner's single campaign through the…

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…

Double-page Qur'an frontispieces are designed as mirror twins but executed in sequence by the same team, and fatigue plus deadline land on whichever page came second. If workshops shared a standard order of operations — something no surviving treatise records — then…

Chinese connoisseurship separates traced copies (mo) from freehand copies (lin) by brush quality — a judgement call. But tracing is mechanical transfer and locks absolute dimensions, while freehand copying rescales freely. Catalogue metadata alone should therefore bifurcate attested copy-pairs into a size-locked…

Collector seals accumulate on Chinese paintings for centuries, and their placement is discussed as taste. The conjecture: placement obeys an interstitial packing rule — each collector takes the best remaining slot in a stable preference order, corners of the image proper first,…

When western Indian manuscript production moved from palm leaf to paper, pages kept palm-leaf proportions and painted vestigial string-hole medallions — that much is known. The unestablished structure is the shedding schedule: vestiges should die in a fixed order, the functional trace…

Imitation coinages degrading over copy-generations — Celtic staters from Philip II's gold, sceattas from Roman types, Indian imitations of Kushan issues — are a numismatic classic. The unestablished universal is an order of decay: under illiterate copying, legend legibility collapses into pseudo-letters…
