One Thousand and One Conjectures

Between roughly 650 and 800 — Byzantium's so-called dark age — the flow of new Greek books nearly stops, yet lead seals, the little stamped discs that closed official letters, keep pouring out by the thousand. Join the two dated series and…

How many copies of a Byzantine author survive is usually explained by genre, sanctity, or school use. This conjecture says his administrative career explains it better: authors who held sealed offices of state or church survive in systematically more manuscript witnesses than…

Some Byzantine officials put verse on their lead seals — a legal instrument turned into a two-line poem. This conjecture says verse seals and verse books belong to the same people: the individuals with metrical seal legends are disproportionately the same individuals…

Officials chose which saint's image to stamp on their lead seals, and monasteries chose which saints' Lives to copy. This conjecture connects the two markets with a lag: the frequency of a saint on dated seals in one century predicts the number…

The Basilika, Byzantium's monumental Greek recension of Roman law, is usually treated as a Constantinopolitan monument. This conjecture says its manuscript geography is really a map of judicial staffing: provenance-localizable witnesses of the Basilika family distribute across provinces in proportion to attested…

Byzantium wrote military manuals — the taktika and strategika — for a thematic citizen army run by generals called strategoi. This conjecture says the manual died with the payroll: new witnesses of military manuals track the administrative life of the thematic armies,…

Schedography — the grammar-exercise literature of Byzantine schoolrooms — floods the twelfth-century manuscript record, and nobody loves it enough for that to be about taste. This conjecture says the flood is the paper trail of a newly credentialed teaching market, visible simultaneously…

A few Byzantine seals quote or echo classical poetry — a flourish of literacy pressed into lead. This conjecture says those quotations are not eclectic: they sample the school curriculum, and in the same rank order that the manuscript market ranks school…

Byzantine book epigrams come mainly in two meters: the learned twelve-syllable line descended from ancient iambics, and the more popular fifteen-syllable 'political' verse. This conjecture says the choice of meter encodes the patron's rank: dodecasyllables for the court elite, political verse and…

The people who paid for books and had their names sewn into them in verse were not simply the rich. This conjecture says they were network hubs: persons named as donors or patrons in Byzantine book epigrams are systematically more central in…

Byzantine letter collections are catalogued under their authors, and we assume they survive by authorial fame. This conjecture inverts that: a collection's witness count scales with the aggregate prominence of its addressees, not with the author's own office or reputation. Copies survived…

In 1204 the Fourth Crusade sacked Constantinople and scattered its libraries. This conjecture says the disaster was selective in a way we can measure: manuscripts carrying dedicatory epigrams naming Constantinopolitan court figures show a deeper survival-curve break at 1204 than equally luxurious…

Byzantium lost southern Italy to the Normans in the eleventh century, and by intuition, political loss should mean textual loss. This conjecture says the opposite happened: Greek manuscripts produced in Italo-Greek scriptoria survive at higher rates than their Constantinopolitan contemporaries, because Norman…

Western watermarked paper eventually replaced parchment in Greek books, and we picture the change as a slow tide spreading east. This conjecture says it moved in legal jumps: the date a Byzantine city's scribes adopt Italian paper follows the date of that…

Greek astronomy — Ptolemy and his commentators — survives in copies made at very uneven intervals. This conjecture says the sky set the schedule: new witnesses of the astronomical corpus cluster in the decade after spectacular, chronicle-attested celestial events, because a comet…

In the Palaiologan period, Greek scholars adapted Persian and Islamic astronomical tables — a famous east-to-west transfer. This conjecture says the transfer moved in diplomatic luggage: each Greek adaptation clusters within a generation after a documented Byzantine embassy to or from the…

The Palaiologan revival of classical learning is usually painted as a diffuse renaissance. This conjecture says it was a series of personal spikes: bursts of new witnesses of a given classical author align with the documented teaching career of an individual professor,…

Women appear as named patrons in Byzantine book epigrams less often than men, but this conjecture is about which women: disproportionately widows. A commissioned book with a verse dedication was a memorial machine — it prayed for the dead husband and displayed…

The verse dedications in Byzantine books vary from two lines to dozens, and the variation looks like poetic whim. This conjecture says it is a price tag: epigram length scales with the market value of the book it crowns, checkable because monastic…

Byzantine chronicles record earthquakes and plagues; Byzantine books record, in dated scribal verses, why they were made. This conjecture joins the two: epigrams invoking deliverance and divine protection cluster in the five years after a chronicle-attested catastrophe in the copying region, because…

In the eleventh century Byzantium debased its famous gold coin, the nomisma, from 24 carats to near junk, until Alexios I minted the reformed hyperpyron in 1092. This conjecture says the monetary crisis is legible in books: dated dedicatory epigrams — proxies…

Before writing a Greek page, the scribe pricked and ruled an invisible grid, and these ruling patterns have been catalogued into hundreds of types. This conjecture says the grids map civil administration: ruling-type clusters among provenance-localizable manuscripts follow the boundaries of the…

Byzantium put dedicatory verse in two places: inside books, and on churches, icon frames, and fresco borders. This conjecture says the two markets shared one workforce: the rate of formula-sharing between book epigrams and dated inscriptional epigrams peaks exactly when church-building booms,…

In the ninth century every Greek text had to pass a needle's eye: recopying from old majuscule script into the new minuscule, or eventual oblivion. This conjecture says the liturgical calendar, not literary fame, decided who passed: church authors with a commemoration…

Why do some minor bishoprics preserve manuscripts older than famous intellectual centers? This conjecture answers with administrative continuity: sees whose bishops form long unbroken sequences on lead seals — attested century after century from late antiquity onward — hold and transmit older…

A monastery's surviving lead seals measure its documentary traffic — the letters, deeds, and petitions its officers sealed. This conjecture says the same measure predicts its book production: per-house seal counts correlate with per-house counts of attributable manuscripts, because archive and scriptorium…

A palimpsest preserves, under its visible text, an older book that someone decided to scrape and reuse. This conjecture says the victims were not random and not doctrinally targeted: they were the administratively orphaned — works whose authors had no institutional afterlife,…

In the tenth century Symeon Metaphrastes issued a stylistically standardized menologion that swept older saints' Lives out of circulation — mostly. This conjecture says the survivors of that sweep map institutional muscle: pre-metaphrastic versions of a Life keep being copied after 1100…

Byzantium preserved small treatises on land surveying and fiscal arithmetic — unglamorous texts with an unexplained copying rhythm. This conjecture says the state's tax cycle set that rhythm: new witnesses cluster around documented cadastral campaigns, the great re-measurements attested by surges of…

Greek Gospels survive in two forms: the continuous text, which anyone might own, and the lectionary, rearranged for reading at services — altar equipment that only a functioning church needs. This conjecture says the ratio between them is a census: the lectionary…

Greek medical compendia — Galenic handbooks, hospital recipe books — were copied in bursts. This conjecture says the bursts ride hospital endowments: new medical witnesses cluster in the decades after the foundation or refoundation of endowed xenones, most visibly the Pantokrator hospital…

An imperial chrysobull — the gold-sealed charter confirming a monastery's estates — looks like agrarian history, not book history. This conjecture says it was a preservation subsidy: houses holding surviving early charters possess manuscript collections with systematically older age profiles than comparable…

Byzantine chronicles, from Malalas in the sixth century to the Palaiologan short chronicles, stop at different moments, and where they stop looks accidental. This conjecture says the stopping point decided their survival: chronicles whose narrative terminus falls at a dynastic change attract…

We blame 1453 for the loss of the imperial library, but this conjecture says the emperors had been exporting it for centuries — through their own gift economy. Manuscripts bearing imperial dedicatory epigrams turn up disproportionately in Western collections with arrival dates…

After Constantinople fell in 1453, émigré Greek scribes in Italy copied furiously, and we treat their output as a market serving humanist demand. This conjecture says it was triage: the émigrés preferentially copied works whose entire earlier witness stock had been Constantinopolitan,…
