One Thousand and One Conjectures

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…

Lanchester's attrition laws distinguish two regimes of combat: aimed fire, where any unit can concentrate on any enemy, yields the square law, in which numerical superiority compounds; frontage-limited melee, where only the front ranks engage, yields the linear law. This conjecture maps…

Barlaam and Josaphat, Kalila and Dimna, the Seven Sages — the frame tales Europe consumed as edifying entertainment — came west out of Eastern Christian and Islamic bookshelves. This conjecture claims the two worlds filed the same books under opposite headings, with…

Hebrew poets in al-Andalus wrote muwashshah-style strophic poems to fit existing Arabic melodies, often naming the model song in a heading. This conjecture claims the named tune functioned as a quality-control device with measurable force: poems whose headings cite a melodic model…

Some Greek texts were copied because churches were required to have them (liturgy prescribed by the typikon), others because readers admired them (homilies, theology, classics). These are different economies: prescribed books face a demand set by the number of altars — every…

In the mid-15th century the Ethiopian emperor Zarʾa Yaʿqob decreed the liturgical reading of the Miracles of Mary in every church. The claim: a commanded text acquires a production signature no organic bestseller shows — a step-function onset in dated witnesses (from…

Nearly everything quantitative about ordinary pre-print writing comes from three preservation flukes — the dry rubbish mounds of Oxyrhynchus, the waterlogged fort at Vindolanda, and the anaerobic clay under Novgorod's streets. These are different climates, centuries, empires, and languages, so if everyday…

A good objection was hard capital: finding an authority who appears to contradict the received position took rare hunting, while supporting quotations lay everywhere, so the dialectical armory was small, curated, and long-lived. This conjecture claims the asymmetry is measurable as differential…

This conjecture claims scholastic diligence was tactically allocated: when writing against an opponent, a master re-verified the opponent's proof-texts in full copies, because a misquoted enemy loses the debate, while continuing to take his own side's supporting authorities on anthology trust within…

Both Latin scholasticism and the Islamic madrasa built commentary stacks on base texts, but their conservation engineering differed: the madrasa's matn was memorized, present in every student's head at every layer, while the Latin Sentences was a rentable written exemplar that a…

Pecia production copied a book from independently rented quire-units, while ijaza and sama' transmission audited a text in continuous certified read-back sessions; this conjecture claims the two quality-control regimes leave physically different error landscapes on the page. Because exemplar peciae circulated and…

Old Javanese famously absorbed an enormous Sanskrit loan vocabulary into its poetry, while Javanese courts simultaneously issued charters studded with Sanskrit legal formulas — and the standard picture treats both as one bilingual 'Sanskrit cosmopolis.' The conjecture splits it: these were two…

When Emperor Zärʾa Yaʿǝqob (reigned 1434-1468) mandated liturgical reading of the Miracles of Mary, copying was driven by decree rather than by demand. Command diffusion and organic diffusion should leave different statistical fingerprints in a manuscript corpus: a decree produces a sharp…

The surviving record seems to say Ethiopia wrote early and the Sahel wrote late: Ethiopian parchment books survive from the first millennium, Sahel books barely from before 1600. This conjecture claims much of that famous asymmetry is a substrate artifact: parchment in…

Scribes copy habits as well as words, and orthographic conventions outlive the practice that created them. This conjecture claims the eighteenth- and nineteenth-century Swahili manuscripts preserve fossil spellings — systematic Arabic-script conventions for Swahili sounds that make no sense within the copyists'…

Africa's two great paper-borne manuscript cultures faced opposite seas: the Sahel imported Mediterranean paper southward across the desert, while the Swahili coast sat on the monsoon circuit to the Gulf and Gujarat. This conjecture claims their books are literally made of different…

Under Tibetan rule, Dunhuang ran one of the earliest well-documented mass book-production projects: thousands of copies of the same sutras, written largely by conscripted local scribes whose names, and their editors' names, survive in colophons. Join industrial quality control to those colophons:…

Oral epic loves verbatim repetition — the messenger delivers the message in the very words we already heard — because for a listener repetition is structure, confirmation, and rest. For a reader it is redundancy, and the surprising connection is that written…

Between Ptolemaic Alexandria and Byzantine Egypt the papyri witness regime change, a new empire, a new religion, and a new law of persons — yet the conjecture is that the proportion of private letters sent by women stays essentially flat across all…
