One Thousand and One Conjectures

Bronze needs tin, and Late Bronze Age tin moved through a long-distance exchange network linking a handful of distant sources to every workshop in the eastern Mediterranean. In network terms, some cities were mere consumers while others were high-betweenness brokers — nodes…

Iron Age hillforts were often built within sight of one another, and lines of sight are functional links: signals, warnings, and social monitoring all flow along intervisibility. Computed from digital elevation models, the intervisibility graph of a hillfort landscape can therefore be…

Joins web-graph topology to hadith science: when Broder and colleagues mapped the early web, they found a bowtie — a small strongly-connected core through which most hyperlink paths route. This conjecture claims the isnad network of the canonical hadith collections has the…

Joins eigenvector centrality — the recursive logic behind Google's PageRank, in which authority flows to those cited by the authoritative — to Roman jurisprudence. The Law of Citations of 426 CE decreed that courts follow five jurists — Papinian, Ulpian, Paulus, Modestinus,…

This connects transmission genealogy with urban market structure. In a metropole a student could shop among a hundred shaykhs; in a small town the household was the archive. Father-to-son transmission (ʿan abihi ʿan jaddihi) was therefore not primarily piety but a thin-market…

This connects the function of the tabaqat genre with a measurable network asymmetry. A biographical notice certifies credentials: it names the subject's teachers because his authority flows down from them, while his students are the future's business and someone else's entry. If…

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…

The map of documented connectivity in Ptolemaic and Roman Egypt is dominated by a few giant private archives — Zenon's roughly two thousand texts alone can make third-century BCE Philadelphia look like the hub of the eastern Mediterranean. If the apparent place-network…

Averroes entered Latin argument as an attachment, summoned to unlock a resistant Aristotle passage, while Avicenna, absorbed earlier and as a system-builder in his own right, circulated free-standing; this conjecture claims the difference is a measurable topological property of citation, not a…

This conjecture claims scholastic self-reference is directional in a way that maps intended curriculum rather than composition history: the occasional works, disputed questions and opuscula, point the reader elsewhere toward the systematic works, while the systematic works rarely point back down, so…

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…

Christian Nubia and Christian Ethiopia were neighbours for eight hundred years, both taking their bishops from the Coptic patriarch of Alexandria — yet each received consecrations, texts, and translations via Cairo. This conjecture claims that shared dependence produced a strict hub-and-spoke information…

Maya monuments name other sites — captures, overlordships, royal visits — which yields a political network; independently, glyphs show site-level formal variants, which yields a paleographic similarity network. The conjecture is that these are the same network: subordinate courts write like their…

The medieval universities of Paris and Oxford built theology by citation: a scholastic quotes Augustine, Aristotle, and a handful of peers, and modern scholars map who-read-whom by counting those citations as a contact network. Ethiopia's Geʽez commentary tradition — the patristic layers…

Thirteenth-century Paris and seventh-century-BCE Babylon both ran commentary industries: the scholastics cited Augustine and Aristotle; Babylonian scholars wrote tablets explicating the omen series and lexical lists, citing canonical works by incipit and invoking other scholarly traditions. The Latin side has been quantified…

The Ur III state of Mesopotamia (around 2100 BCE) left roughly a hundred thousand administrative tablets, and Assyriologists learned to reconstruct its bureaucratic hierarchy statistically — disambiguating names and inferring rank from who appears with whom, and in what position, across thousands…

Hadith science built the most formal transmission-audit apparatus of the premodern world — the isnad, a chain of named transmitters — and modern analysis tests those chains statistically, checking generation-lengths against plausible lifespans and finding "common links" where a diffuse tradition was…
