One Thousand and One Conjectures

Copies per text follow preferential attachment: power-law copy counts, with survival size-biased so bestsellers over-survive superlinearly. Falsify: medieval library catalogs vs extant counts.

Joins macro-econometric common-shock identification to Eastern Christian codicology: a conquest wave is legible as a synchronized same-decade production trough across manuscript traditions that share geography but nothing else, while an out-of-theater tradition serves as the control arm.

Data collapse from critical phenomena meets manuscript transmission: Greek works at large and Byzantine book epigrams are different genres copied under different incentives, yet their witness-count distributions should collapse onto a single curve after rescaling by the mean, because textual survival has…

Cuneiform sign inventory grows with corpus size by Heaps' law, and the exponent should collapse during Old Babylonian school standardization. Falsify: the digitized CDLI corpus.

Genuine Linear B tallies should be Benford-conformal; assessment records (quotas) should deviate — statistically separating what was counted from what was demanded. Falsify: digit distributions by tablet series.

The mutually derivable columns of Easter tables (golden number, epact, dominical letter, indiction) form a redundant error-correcting code that medieval users actually exercised.

Scribal error-apology formulae (“forgive the faults of the unworthy scribe”) are costly quality signals from careful scribes, not confessions from sloppy ones.

Letter-order mutations in attested abecedaria (transpositions, insertions, deletions) accumulate roughly per teaching generation along the alphabet's transmission tree.

Manuscripts became binding waste on an institutional obsolescence clock, not a material wear-out clock.

Monastic copying was counter-cyclical to farm labor; professional urban copying was not — so the seasonality amplitude of dated colophons is a quantitative urbanization index of book production.

Production mode (visual exemplar copying vs dictation/pecia mass production) is recoverable from error typology alone.

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

Staff notation cut chant copying errors discontinuously: predict per-neume Levenshtein error drops by half across the Guidonian transition within single traditions. Falsify: aligned chant stemmas.

Within a scriptorium, per-copy error rates are constant enough to date manuscripts by error accumulation, like a decay clock. Falsify: error counts vs colophon-dated families.

Computational errors in dated horoscopes are inherited from specific copies of astronomical tables — so recomputing surviving horoscopes reconstructs the copy-tree of the tables themselves. Falsify: recompute and cluster.

Oral-epic formulas are redundancy bits: formula density should rise with local information load (names, numbers, catalogs) within Homeric and South Slavic lines. Falsify: corpus regression.

Vedic oral transmission's error rate per syllable-century is orders of magnitude below manuscript copying of comparable Sanskrit texts — quantify both for the first time. Falsify: Rigveda variant counts vs Mahābhārata manuscript variance.

The Aṣṭādhyāyī's rule ordering sits near the minimum-description-length optimum over permutations of its own rules. Falsify: computational reordering search.

Comparing Chinese, Korean, Japanese, and Arabic records of the same celestial events yields a censorship index: Chinese omissions should cluster in usurpation and legitimacy-crisis decades. Falsify: comparative event catalogs.

Generalizing the famous 190 Themistocles sherds cut by a few hands: handwriting clusters on ostraka should predict deposit location — ward-level bloc voting, measurable. Falsify: paleographic clustering plus findspots.

Pompeian wall dialogues should follow the same reply-depth distribution as modern forum threads — conversational universals across two millennia. Falsify: CIL IV thread reconstruction.

His distance errors should grow log-normally with informant hops from the Aegean — rumor as multiplicative noise. Falsify: reported vs true distances.

The map's segment errors should cluster by province, revealing the distinct source itineraries it was compiled from — stemmatics of a map. Falsify: error-variance clustering.

Its repeated-glyph statistics should match the Markov structure of recitation genealogies, not prose language. Falsify: sequence entropy against chant corpora.

Joins autocatalytic reaction kinetics to the sociolinguistics of conquest: language replacement in Egypt's documentary record behaved like a chemical substitution with a nearly universal rate constant, so Arabization differed across regions only in onset time, never in speed.

Joins atmospheric physics to colonial sociolinguistics: Greek thinned with river distance from Alexandria the way pressure thins with altitude, at a fixed exponential scale length, because demand for the administrative language decayed with distance from the metropolitan port.

Joins capture-recapture ecology to Greek philology: works attested by exactly one and exactly two witnesses play the role of singleton and doubleton species, so the Pinakes witness-count table is an ecological sample from which the size of the lost Greek library is…

Joins neutral models of cultural evolution to Byzantine paratexts: if book-epigram copying were preferential attachment, older epigram types would accumulate more occurrences simply by exposure; instead popularity is fixed at birth by intrinsic fit to scribal needs, and age buys almost nothing.

Joins the cognitive psychology of recall (the serial-position curve: primacy and recency beat the middle) to the stemmatics of oral law: Icelandic law was recited from memory in fixed thirds over three years, so when it was finally written down, the middle…

The single-factor market model from asset pricing meets Eastern Christian book production: doctrinally separated traditions (Syriac, Armenian, Coptic, Ethiopic, Georgian and others) nonetheless load on one common macro-shock factor, so their production time series co-move like stocks in a single market despite…

Phase separation from soft-matter physics meets monastic geography: mixed-tradition manuscript centres are unstable — a place either purifies toward a single tradition or becomes a genuine multi-tradition entrepot, and the half-mixed middle of the spectrum is depleted, like oil and water demixing.

The cutting-stock problem of operations research meets codicology: parchment page sizes are not aesthetic free choices but near-optimal cuts of animal skins, so leaf dimensions quantize at dyadic folds of regional skin rectangles, while paper leaves, cut from standard moulds, cluster at…

Technology-diffusion lag curves meet Timbuktu codicology: the Sahara's intellectual bandwidth tripled between 1400 and 1600, so the delay between a work's composition in the Islamic heartland and its first dated West African copy collapsed as the trans-Saharan book trade routinized.

Capture-recapture census statistics meet Sanskrit anthology studies: the great subhashita collections are quasi-independent samples from a floating ocean of stanzas, so their pairwise overlaps yield a census of that ocean — and it dwarfs everything that survives.

Packet-switched content distribution meets the medieval university book trade: the pecia system chunked exemplars into pieces copied in parallel and reassembled, so stemmatic affiliation should switch at known pecia boundaries — an error signature that continuous-exemplar copying cannot produce.

This connects the diplomatics of multi-session audition certificates (samaʿat) with the incentive structure of certification. A samaʿ record for a long book lists who attended which sessions, and the legal and spiritual payoff was concentrated at the end: transmission rights vested at…

This connects Arabic quire structure with the economics of the paper trade. Arabic codices characteristically use quinions (five-bifolium gatherings) where Greek, Syriac, and Latin books use quaternions, and the difference is usually filed under scribal custom. The conjecture: the quinion is a…

This connects selective diacritical pointing in early Arabic documents with the sociology of correspondence. Pointing cost time and scribes applied it selectively; the question is what governed the selection. The conjecture: pointing density tracks social distance between writer and recipient. Between intimates,…

This connects hisba-literature complaints about copyists with measurable page economics. The market inspectors' manuals warn that copyists paid by the quire enlarge their script and widen spacing to inflate the folio count. If the warning tracked real practice rather than moralist boilerplate,…

This connects collation practice with the error spectrum of the resulting copies. Muqabala was typically performed aloud: one party reads the exemplar while the other follows the new copy. An acoustic channel catches what the ear can hear, namely omitted words, skipped…

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 the market for isnad elevation (ʿuluww) with the demography of audition sessions. Families brought small children to auditions to mint transmitters whose chains would be enviably short seventy years later; that custom is known. The sharpening: child-bringing was priced arbitrage,…

This connects transmission genealogy with urban market structure. In a metropole a student could shop among a hundred shaykhs; in a small town the household was the archive. Father-to-son transmission (ʿan abihi ʿan jaddihi) was therefore not primarily piety but a thin-market…

This connects the function of the tabaqat genre with a measurable network asymmetry. A biographical notice certifies credentials: it names the subject's teachers because his authority flows down from them, while his students are the future's business and someone else's entry. If…

This connects Ibn al-Nadim's profession with the mortality structure of his catalogue. The Fihrist of 377 AH was compiled by a warraq from stall-level knowledge: it records inventory, including the ephemera of a living market that scholars never canonized. A title known…

This connects the one substantially surviving medieval Arabic institutional library catalogue with household book culture. An endowed library and a scholar's home solved different problems: the home held the curriculum, the matns, the working copies a man taught from and annotated; the…

This connects Islamic endowment law with the diplomatics of ownership statements. A waqf book was inalienable in perpetuity, so private possession of one was legally embarrassing: a signed, dated tamalluk note on an alienated endowment book is a confession in the owner's…

This connects market law with the division of epistemic labor in the book trade. The hisba manuals regulate bakers' loaves and druggists' compounds, and they also cover the warraqs. The conjecture: their copyist clauses police only the material object, fading ink, badly…

This connects Ottoman probate evidence with the economics of a copyright-free book market. Where any text could be lawfully recopied by anyone, the work itself commanded no rent; scarcity lived entirely in the object, in the calligraphy, illumination, paper, and binding. 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.…
