One Thousand and One Conjectures

Among the ostraka cast against Themistocles, a famous deposit of 190 sherds turned out to have been inscribed by just a few hands — prepared ballots, evidently readied for distribution to voters. The conjecture generalizes this find into a testable model of…

The walls of Pompeii preserve genuine written conversations: graffiti that answer, mock, and extend earlier graffiti on the same surface, recorded in CIL IV. Modern online forums show a robust statistical signature in how such exchanges unfold — the distribution of reply…

The Shang kings at Anyang divined by heating cattle scapulae and turtle plastrons until they cracked, reading the cracks as answers — and the inscriptions often record the sequence in which the questions were put. Crack formation, driven by micro-structural accidents of…

Joins index-number theory — the chained construction behind the modern consumer price index — to Tamil temple epigraphy. Thousands of dated Chola-era endowment inscriptions record in stone the rates of paddy, ghee, and oil required to keep a temple lamp burning in…

Joins the concentration indices of industrial organization — the tools economists use to tell competitive markets from managed ones — to Indus glyptic. Stamp seals were the emblems of whoever ran Indus commerce, and if their animal motifs were the competing badges…

Quranic recitation (tajwid) is an oral discipline, and monumental Quranic inscriptions are stones; the two literatures barely touch. This conjecture claims early Islamic inscriptions encode recitation: choices of where inscribed Quranic excerpts begin and end, and their deviant or archaic orthography, follow…

Pilgrims at Egyptian temples scratched proskynemata — 'I, so-and-so, made obeisance before the god' — and the genre had an economy: a longer, more elaborate act of written presence was worth more to a visitor the farther he had come, since the…

Pre-print South Asia split its writing between media by time-horizon: perpetual claims — land grants, endowments — went onto copper and stone, while knowledge went onto perishable leaf, to be renewed by recopying. If that split was a functioning division of labour…

Thousands of copper-plate grants record their brahmin donees with gotra and Vedic śākhā — which recension each man was trained to recite — because the gift's ritual efficacy depended on it. Read together, the plates are something the manuscript record can never…

Hero-stones — memorials to men killed in cattle raids and local battles — carpet the pastoral and frontier zones of the Deccan and western India, dated and localized by the thousand. Sanskrit knowledge production, by contrast, ran on agrarian surplus channelled through…

The men who composed copper-plate praśastis were trained kāvya poets, and some signed their names on the plates themselves. If the same labour pool wrote plate eulogies and transmitted literature, a measurable fraction of named plate poets should reappear in the prosopography…

A copper-plate grant needed only the legal facts, yet over the centuries grants swelled from terse deeds into long genealogical praśastis running to hundreds of lines — and engraving cost scales with length, so the inflation was a paid-for choice. The cheapest…

Temple and monastic donative inscriptions occasionally record gifts of books — titles, sometimes counts, dated and localized — which makes them tiny dated library catalogues in a medium that survives without recopying. Because stone samples the act of donation while manuscript catalogues…

Everyone knows the print run as Gutenberg's invention; fewer know that in the late twelfth century the Khmer king Jayavarman VII had a nearly identical Sanskrit edict engraved on stelae at hospital foundations scattered across his empire — the same text, many…

The zero digit is celebrated as a triumph of Indian mathematics and astronomy, yet the earliest securely dated zero symbols known anywhere survive in seventh-century Southeast Asian inscriptions, including the Khmer stone conventionally cited as bearing a śaka date of 605 (683…

Classical Khmer inscriptions are famously two-faced: Sanskrit verse hymning gods and kings, and Khmer prose listing rice-fields, servants, and boundaries. This conjecture says the Khmer half is not composition but transcription — extracts copied onto stone from working administrative documents on perishable…

Ecologists estimate unseen animal populations by capture-recapture: tag what you catch, and count how often you catch it again. Javanese copper-plate charters permit the same trick on documents, because later courts re-issued and re-engraved older grants (the tinulad copies), so a single…

Javanese land charters end with lurid curses — violators to be reborn in hell, devoured by demons, split like a plucked bird — and political economists have long known that states substitute among enforcement technologies. Join the two: where an administration can…

Manuscript scholars diagnose visual copying by the saut du même au même: the copyist's eye jumps from one occurrence of a word to its next occurrence, silently deleting the span between. Khmer temple inscriptions carry enormous repetitive lists — servants' names, rice…

Evolutionary biologists know that molecular change tracks generations rather than calendar years: fast-breeding lineages accumulate mutations faster. Apply that familiar clock to the Pallava-derived scripts of Southeast Asia, which are unusually datable because so many inscriptions carry exact śaka dates: the conjecture…

The Sanskrit poetry on Khmer stelae constantly echoes Indian models — schoolroom similes, courtly kavya tropes, epic tags — and every identifiable quotation or close allusion is in effect a library call against holdings we will never shelve. The conjecture is that…

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…

Old Javanese kakawin reproduce intricate Sanskrit syllable-weight metres so unforgiving that a single wrong quantity breaks the line — in a language whose own phonology does not natively mark vowel length the way Sanskrit does. Sustaining that discipline for centuries is the…

The inscriptions of Campā begin overwhelmingly in Sanskrit, pass through centuries of Sanskrit-Cham bilingualism, and end in Old Cham alone — a whole written language dying in public, on dated stones. The conjecture treats this as a measurable collapse with the dynamics…

Angkorian Cambodia and Campā were rivals with different politics and increasingly different religious trajectories, yet written Sanskrit dies in both epigraphies within roughly the same two or three generations around the thirteenth to fourteenth century. The conjecture: the synchrony is not coincidence…

Khmer inscriptions record women as principal donors, land-sellers, and founders at rates that would startle a reader of most medieval documentary cultures. Join this to property law: where inheritance runs substantially through women, transaction records must name women as principals, so the…

Angkorian temple inscriptions enumerate thousands of temple servants and slaves by personal name — the largest named non-elite population to survive from pre-1500 Southeast Asia, recorded incidentally by donors bent on glory, not on demography. The conjecture joins onomastics to population science:…

Angkor ran one of the largest premodern states while minting no coins: its inscriptions state prices in rice, cloth, silver by weight, and livestock equivalences. Join that famous coinlessness to the ledger theory of money — the view that money is fundamentally…

The standard story of writing's arrival in island Southeast Asia is literary and liturgical: Sanskrit hymns first, vernacular poetry after. But the earliest dated vernacular texts of the archipelago are seventh-century Old Malay state documents from Srivijaya — expedition records and, above…

Javanese sima charters routinely enumerate the mangilala drwya haji — the crown revenue-takers whose claims the grant extinguishes — dozens of exotic job titles, from toll-men to keepers of fighting cocks. Join this list to a phenomenon every modern reader knows from…

Javanese charters date themselves with what looks like absurd redundancy — a single day fixed by tithi, several concurrent week-cycles, the lunar mansion, and more, where one system would do. Join this to information theory: redundancy is exactly what error-detecting codes are…

Certain invocations and royal-title formulas in Cham inscriptions recur essentially verbatim across spans of centuries — sentences that outlive the dynasties that first cut them. Join textual formula to the geneticist's notion of a conserved sequence: text that refuses to mutate across…

Khmer inscription production is famously uneven across reigns, usually explained by royal piety or building programs. Join the epigraphic time-series instead to a truth every property lawyer knows: when title is insecure, everyone rushes to re-register. The conjecture is that bursts of…

We cannot read a single pre-1500 Khmer palm-leaf book, but the stones talk about documents constantly: royal orders received, prior deeds consulted, registers checked, rulings recorded. The conjecture is a deliberately austere piece of accounting: treat every explicit epigraphic mention of a…

Between roughly the fourth and seventh centuries, Indic writing appears across a vast arc from Borneo to the mainland in scripts of broadly Pallava type — the textbook 'Indianization.' The conjecture sharpens the diffusion into a countable process: the radiation stems from…

Javanese copper-plate charters were engraved as legal instruments, and their letterforms often suggest an engraver reproducing the chancery hand of a perishable original, whereas stone inscriptions display formal monumental script. Join the two media as a palaeographic stereo pair: the systematic difference…

A number of Khmer inscriptions narrate property disputes: claims traced through generations, prior royal decisions invoked, transactions from earlier reigns rehearsed with dates and amounts. Join this to a simple cognitive limit — unaided living memory in a litigating community reaches back…

Campā is conventionally narrated as a kingdom with a sequence of capitals moving down the Vietnamese coast. Join its epigraphy to settlement science's rank-size rule: in a centralized state the leading centre dominates document production (a 'primate' distribution), while a confederation of…

Around 929 CE the Javanese court abruptly abandoned the Central Javanese heartland for East Java — one of the sharpest geographic breaks in the premodern record, visible as a near-instant relocation of all charter production. The conjecture joins this rupture to institutional…

Hundreds of named elites — priests, officials, royal kin — recur across multiple Khmer inscriptions at different temples and provinces. Join prosopography to network science: link every co-attestation of named individuals into a graph, and its shape measures how integrated the Angkorian…

Khmer inscriptions frequently record donations of inscribed precious-metal objects — gold and silver vessels, plates, and images bearing writing — yet almost none survive, because metal text is self-liquidating: it is melted whenever its bullion outvalues its words. The conjecture turns this…

The Old Javanese prose adaptations of the Sanskrit epics — the parwa literature of around the tenth century — exhibit a curious rhythm: a Sanskrit quotation, then an Old Javanese paraphrase, alternating for hundreds of pages. Join this to a schoolroom technology…

Distances cut into itinerary stones and painted into map legends ought to be independent measurements of the world. The surprising connection is that they share scribal corruptions with the written itinerary tradition: numeral errors born on papyrus and parchment were carved into…

Unseen-species estimators — the mathematics behind estimating how much medieval Latin literature is lost — need only one ingredient: repeated independent sightings of the same underlying items. The stone inscriptions of Angkor-era Cambodia provide exactly that ingredient in an unexpected form: Old…
