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.

Parchment was a livestock derivative, so manuscript production absorbed herd shocks: colophon-dated production series in NW Europe should dip with a 1–3 year lag after documented cattle murrains, with no equivalent dip in paper-based production once paper is available as a control.

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.

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.

Viking hack-silver should follow the universal power-law mass distribution of brittle fragmentation; deviations mark the arrival of weighed-payment standards. Falsify: fragment masses in Cuerdale and Spillings hoards.

The latitudes engraved on surviving astrolabe plates should follow the population distribution of customer cities — medieval product-line economics. Falsify: plate-latitude inventories vs city-size estimates.

Relic translations should cluster in the five years before major building fundraising — acquisitions as anchor investments. Falsify: translation dates vs cathedral fabric accounts.

Shrine market shares (Thames badge finds) follow Polya-urn path dependence: early leads persist beyond what miracle registers justify. Falsify: badge chronology vs miracle-count records.

As Greenland ivory prices fell against elephant ivory, Norse hunters intensified into riskier, more distant grounds — income-target behavior, not profit maximization. Falsify: the existing ivory isotope sequence against price series; profit-maximizers would have quit, not pushed north.

English market charters before the 13th-century spacing statute should already show the statutory spacing — law codifying a self-organized equilibrium, not creating one. Falsify: charter geodata pre- and post-statute.

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.

Daughter houses space themselves by competitive exclusion into a tessellation with a minimum-distance rule, violated only along wool routes. Falsify: foundation geodata.

The fair calendar is a solved traveling-merchant problem: dates minimize total circuit dead-time, and its wartime breakdown measurably rerouted trade to sea. Falsify: calendar optimization plus toll series.

Kontor privileges track member cities' route-control Shapley values and re-rank after route shocks. Falsify: privilege lists vs network model.

Piece-form boundaries (elephant becoming bishop) should coincide with documented rule-variant boundaries — objects tracking rules across Eurasia. Falsify: find typology vs textual rules.

Successive Gothic campaigns move monotonically toward the thrust-line optimum — iterative structural learning with a measurable decreasing loss. Falsify: dated buttress geometries under limit analysis.

Cathedral heights escalate against rivals within a diocesan radius by roughly fixed increments until the material frontier (Beauvais's collapse sits exactly there). Falsify: height/date/distance panel.

Pre-theoretic builders converged on a diameter-to-length power law near modern acoustic optima — empirical physics before physics. Falsify: measured medieval pipework.

Founding-pitch standards diffuse along rivers and trade routes, forming dialect-like isogloss maps. Falsify: dated bell frequency surveys.

Viking plank widths and scarf spacing sit at the crack-arrest optimum for oak — naval architecture as fracture mechanics. Falsify: ship-timber metrology plus material testing.

3D-scanned step erosion ranks pilgrimage volumes; wear-derived rankings should match offering and indulgence registers. Falsify: scans along the Compostela routes.

Exchequer tally notch geometry encodes redundancy beyond face value — anti-fraud bits in a split physical token. Falsify: metrology of surviving tallies for non-value-bearing regularities.

Post-1200 church orientation errors should trace the geomagnetic declination curve — dating compass adoption in the building trades and refining archaeomagnetism at once. Falsify: orientation databases vs paleo-declination.

Chart accuracy per route scales as 1/√(voyage traffic) — maps as averaged compass logs. Falsify: cartometric route error vs traffic proxies.

Medieval strip scattering tracks the local yield covariance matrix (recoverable from modern soil data): more scattering where covariance is low across micro-zones, early consolidation where it's high. Falsify: field-system GIS vs soil covariance.

Watermill adoption follows a Bass curve whose innovation coefficient is set by monastic presence — monks as the p-parameter of medieval technology. Falsify: dated mill records by region.

Nave RT60 and repertoire co-evolved: long-reverb churches correlate with slower, more melismatic chant and early organum. Falsify: acoustic measurement of Romanesque/Gothic naves vs local repertoire.

Norse assembly sites sit at open-air speech-intelligibility optima of their landscapes, beating matched control locations. Falsify: acoustic modeling of thing sites vs controls.

Mark distributions across coursework reconstruct shift schedules: batch sizes should be Poisson and gangs should alternate by course. Falsify: mark spatial statistics at documented cathedrals.

Trace-element signatures in blue stained glass should shift with documented disruptions of Asian trade routes — windows as sensors of Eurasian politics. Falsify: dated glass panels vs route-history chronology.

Joins stream-power hydrology to the fiscal cadastre: the 1086 Domesday survey unwittingly recorded a physics meter, because a mill's render capitalized the hydraulic power of its site; feudal rent should therefore scale with drainage-area-times-slope like an engineering formula.

Joins process-engineering labor accounting to Viking naval history: the binding constraint on Norse sea power was textile throughput, not shipwrights; a large woolen sail embodied more person-hours than the hull it drove, so fleets could grow only as fast as spinning capacity.

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 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…

Vertical-monopoly pricing from industrial organization meets the toll castles of the Holy Roman Empire: a chain of independent tolls on one river overcharges relative to a single owner, so consolidation of adjacent tolls under one prince should cut the combined rate and…

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.

Common-value auction theory meets Venetian state finance: the incanti — annual auctions of state galley charters — were common-value auctions in which patrician bidders demonstrably learned to shade bids across 150 years, the earliest documented winner's-curse correction.

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…

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 runic acrostic signatures of Cynewulf — a poet who engineered personal credit into his verse — to oral-formulaic theory's central variable: a poet composing for written attribution has an incentive not to sound like everyone else, while anonymous traditional composition…

Connects the classroom habitus of glossing to stemmatic topology: a schooltext lived its life open beside other copies, its margins stuffed with variants and explanations that the next copyist promoted into the text, while a rarely read historian was copied once a…

Joins the cataloguer's oldest headache — incipit drift — to prosody as an error-correcting code operating exactly where texts are most vulnerable: openings, which suffer lost first leaves, added prologues, and scribal throat-clearing. A verse work's first lines are locked by rhyme…

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…

Joins skaldic poetry's survival to a citation-driven preservation model: drottkvaett stanzas were too dense to read for pleasure once the courts that paid for them dissolved, but sagas and kings' lives needed them as evidence — quoted testimony anchoring prose claims —…

Connects the invention of the troubadour vidas and razos — the prose lives and song-explanations in the chansonniers — to an export-market failure: at home in Occitania the songs circulated inside a living performance scene that supplied all needed context, but the…

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…
