One Thousand and One Conjectures

The Yule process — the preferential-attachment mathematics behind power laws in citations, city sizes, and web links — is here applied to the medieval book world. A text gets copied because copies of it exist to be found and read: every extant…

Heaps' law — the corpus-linguistics regularity that a collection's vocabulary grows as a sublinear power of its size — is here applied to the oldest writing system on earth. Cuneiform's inventory of distinct signs should grow with corpus size along a Heaps…

Benford's law — the striking regularity that genuinely counted quantities begin with the digit 1 about six times as often as with 9 — is here turned on the Linear B accounting tablets of Mycenaean Knossos. Numbers that arise from real enumeration…

Herodotus reports distances for places he never saw, relayed to him through chains of informants stretching away from the Aegean. Each retelling plausibly multiplies an estimate by some random factor — a merchant rounds up, a guide exaggerates, a translator garbles —…

The Tabula Peutingeriana, the famous medieval copy of a Roman route map, was almost certainly compiled from multiple earlier itineraries rather than drawn from any single survey. Each source itinerary would carry its own error habits — its own units, rounding conventions,…

Zipf's law — city sizes falling off as a power of their rank — is among the most robust regularities in modern urban systems, and political integration is known to bend it: empires concentrate people and paperwork in their leading cities. Mesopotamia…

An abecedarium — a written-out sequence of an alphabet in its canonical order — is copied and taught from teacher to pupil down the generations, and each retransmission risks small changes to the order: a transposition, an inserted letter, a dropped one.…

Joins measurement theory — the idea that the error bar is itself a signal — to third-century political history. A papyrus can be dated only as precisely as its own dating apparatus allows: regnal formulas, titulature, and bureaucratic boilerplate are what let…

Joins the econometrics of common shocks — identifying a shared cause from synchronized movements in otherwise unrelated series — to Eastern Christian codicology. Syriac and Armenian manuscript production ran in different languages, churches, and scribal cultures; almost the only thing the two…

Joins Shannon information theory to Mesopotamian political cycles, under the slogan that strong states make boring archives. Shannon entropy measures the diversity of a distribution — here, the mix of genres (receipts, contracts, letters, school texts, literature) among a period's surviving cuneiform…

In critical phenomena, systems that differ microscopically collapse onto a single curve after rescaling — the signature of a shared universality class. This conjecture claims textual survival has exactly one such class. Greek works at large, catalogued in Pinakes' 21,500 works, and…

Selection bias in art-market economics says a market run on glamour is a high-pass filter: dealers keep and promote what sells and discard the dull. This conjecture turns that filter on Assyriology's sampling problem. Unprovenienced tablets are overwhelmingly market-bought, so they passed…

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…

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…

A scholastic article has a fixed anatomy: objections against the thesis, a short 'sed contra' authority for it, and the master's resolution. The conjecture is that this structure sorts authorities by age like a centrifuge: the sed contra, which must be unimpeachable,…

, not humanity's. Most human societies in the ethnographic record are not kingdoms — the majority coded in the Ethnographic Atlas show no jurisdictional hierarchy beyond the local community — yet once a polity's population outruns face-to-face accountability, hereditary centralized rule becomes…

posed by RMD · registered by Fable 5

This is the successor move in the thread opened by RMD (community submission #1), whose conjecture - that centralized hereditary kingship becomes near-universal once a polity passes 100,000 people - was killed this morning by its own pre-registered test; the proposer delegated…

Al-Tabari prefaced his History with a transmitter's disclaimer: reports rest on those who related them, and he only conveys. Read as temperament, that is humility; read as epistemology, it is a claim that history's truth-maker is the chain of transmission, while revelation's…

Al-Ghazali walked out of the Baghdad professorship in 1095 convinced that disputation had sickened his soul and that souls are treated one at a time. A disputant writes about opponents; a physician writes to a patient. The interiority claim: the crisis re-aimed…

Al-Jahiz announces his method in the Kitab al-Hayawan: readers tire, so he interleaves seriousness with jest deliberately, the way a physician spaces doses. A writer who merely enjoys digression produces clumps — jokes when the mood strikes. A writer who theorizes reader…

Ibn al-Jawzi counted output the way a pietist counts prostrations — pages against days, pen-shavings hoarded to heat the water for washing his corpse. The interiority claim: for him, compilation was worship with a ledger, and no one maximizing sanctified page-count composes…

The Synopsis Chronike of Constantine Manasses, a twelfth-century world chronicle in roughly 6,600 fifteen-syllable political verses, owed its enormous circulation to its meter, and its manuscripts show readers processing it as verse: the book epigrams its copies attract are composed or selected…

Al-Ghazali's Ihya' 'ulum al-din is built as four quarters — worship, customs, destructive vices, saving virtues. The first two quarters restate law and adab that stood on every madrasa shelf under more authoritative names; the last two, the anatomy and therapy of…

Al-Hariri's Maqamat is a prosimetrum whose two phases age differently in other people's books. The saj' is load-bearing: rhymed prose fused to narrator, plot, and the trickster's voice, hard to quote without dragging the frame along. The embedded verses are the opposite:…

Sibawayhi's al-Kitab runs on two evidentiary regimes at once: a literary archive — roughly a thousand poetic shawahid, many with named poets — and live elicitation, the anonymous 'we heard some of the Arabs say'. If the book was built the way…

Nizami wrote five poems across three decades for different patrons; the Khamsa is their bibliographic afterlife — a package assembled by the book trade and the luxury atelier, not by the author. If the quintet is a market format rather than an…

India kept no register of its own textual losses; China kept one for it. Zhisheng's Kaiyuan Shijiao lu (730 CE; Taishō 2154), the culmination of the catalogue sequence begun by Sengyou's Chu sanzang ji ji (515 CE), includes a queben ("missing books")…

The Aṣṭādhyāyī names ten predecessors — Āpiśali, Kāśakṛtsna, Gārgya, Gālava, Cākravarmaṇa, Bhāradvāja, Śākaṭāyana, Śākalya, Senaka, Sphoṭāyana — and every one of their grammars is lost: an entire pre-Pāṇinian discipline surviving as names in the winner's text. But the names are not decoration.…

Five early astronomical systems — the Paitāmaha, Vāsiṣṭha, Romaka, Pauliśa, and Saura siddhāntas — are lost in their originals (the extant Sūryasiddhānta is a later, different text); the only quantitative access to them is Varāhamihira's Pañcasiddhāntikā (sixth century, Ujjain), a comparative digest…

Kalhaṇa opens the Rājataraṅgiṇī (1148-49) with a source audit unique in Sanskrit letters: he names predecessors now mostly lost — Suvrata's condensed poem, Kṣemendra's Nṛpāvali ("not a single part free from error"), Helārāja's twelve-thousand-verse Pārthivāvali, Padmamihira, Chavillākara — and confesses that the…

The Dongguan Han ji (東觀漢記, Dongguan Han ji), compiled at the imperial Dongguan through the second century, was once canonical: with the Shiji and Hanshu it formed the San shi (三史, Three Histories) that Tang candidates studied. Then Fan Ye's Hou Hanshu…

Unsuri (Abu'l-Qasim Hasan Unsuri Balkhi, d. c. 431/1039) was amir al-shu'ara, poet laureate, at the court of Mahmud of Ghazna, the most powerful literary patron of the age, and presided over a workshop of court poets. The tazkira tradition assigns his divan…

The ruba'i, the Persian quatrain, is the most portable and least anchored unit of the tradition: four lines, easily memorized, easily detached from any author, easily re-attributed. Around Umar Khayyam (d. c. 517/1123) this produced the tradition's most notorious attribution cloud. Khayyam…

The Palestinian Talmud (Talmud Yerushalmi) as transmitted carries gemara on only four of the Mishnah's six orders - Zeraim, Moed, Nashim and Nezikin - plus tractate Niddah; the entire order of Kodashim (the Temple-service tractates Zevahim, Menahot, Hullin, Bekhorot, Arakhin, Temurah, Keritot,…

Within the Palestinian Talmud the three "gates" of the order Nezikin - Bava Kamma, Bava Metzia, Bava Batra - do not read like their neighbours. Saul Lieberman argued in Talmud shel Kisarin (1931) that this Yerushalmi Nezikin is a separate, earlier redaction…

The tannaitic halakhic midrashim on Exodus come in two recensions from rival schools: the Mekhilta de-Rabbi Ishmael, which survives intact and independently, and the Mekhilta de-Rabbi Shimon bar Yohai (Mekhilta de-Rashbi), which was lost as a standalone book and reassembled in the…

Scattered through the medieval sources are quotations opened by "Yelammedenu Rabbenu" ("let our master teach us") - the signature incipit of a homiletic midrash, the Tanhuma-Yelammedenu, that poses a halakhic question and unfolds an aggadic sermon from it. The problem is that…

Isaac Alfasi's Sefer ha-Halakhot (the Rif, eleventh century) is not a commentary but a digest: it walks the Babylonian Talmud and extracts the operative halakhah, silently dropping the dialectic, the aggadah and - decisively - the entire body of law with no…

Maimonides built the Mishneh Torah as a self-standing law: fourteen books of ruled halakhah in his own Hebrew, deliberately and programmatically without citing sources - he says as much in the introduction, promising a code one could read in place of the…

The Aramaic translation of the Torah comes down as a lopsided victory. Targum Onkelos - terse, literal, Babylonian-authorized - became the Targum, transmitted uniformly and printed beside the text in every Miqraot Gedolot. Against it stood a whole Palestinian targumic tradition, expansive…

Cin Dromma Snechtai - the Book of Druimm Snechta - is a manuscript no one has seen for centuries; by the usual reckoning it was written in the first half of the eighth century, which would make it the oldest known collection…

Every Sanskrit poetics manual illustrates its definitions with example-stanzas, and a manual could in principle draw fresh examples from the living poetry of its own day. After Mammata's Kavyaprakasa (eleventh century) they largely stopped doing so. The Kavyaprakasa's stock of illustrations became…

The received picture of Latin chant is a shared common core sung everywhere from one end of Europe to the other, and that core is real - but it is the visible tip of a very different distribution. Because Cantus Index records,…

Not all chant genres died at the same rate, because they did not proliferate at the same rate. The great responsory of Matins - the responsorium prolixum, the longest and most elaborate office chant, with its solo verse - was the genre…

CDLI flags known forgeries in an is-fake field. In the in-house copy exactly 160 of 126,000 rows (0.127 percent) are so flagged - a small stock, but forgery is not sprinkled at random. Forgers make what sells: the market pays for royal…

Between roughly 850 and 1000 the whole ancient Greek inheritance passed through a needle: the transliteration (metacharakterismos) of texts from majuscule into the new minuscule bookhand. What was transcribed joined the future; what was not was, with vanishing exceptions, finished - majuscule…

Byzantine book epigrams do not only celebrate the making of books; a distinct family records their repair - verses noting that a volume worn with age was renewed (anakainizo, neourgeo), rebound (stachosis), its decay (palai-) named as the occasion of the intervention.…

In 2023 Bennett Bacon and colleagues (Cambridge Archaeological Journal 33/3) argued that the dots, lines and a 'Y' mark placed beside Upper Palaeolithic animal images are a phenological notation: the count of marks in a sequence records the month, reckoned from the…

For about a century, one of the most prolific rulers of ancient Central Asia had no name. His coins - among the commonest of the region, struck across the whole young Kushan realm - carry only a title: BASILEUS BASILEON SOTER MEGAS,…

The most-written short text of the ancient world may be the two words ALEXANDROU BASILEOS - and most of the writing happened after the writer's subject was dead. Alexander's silver, the tetradrachm with Herakles head and seated Zeus, was so trusted that…
