One Thousand and One Conjectures

Chant scholars know a 'Germanic' melodic dialect exists; linguists know the High German consonant shift drew sharp isoglosses across the same map. The conjecture joins them: the boundary of the Germanic chant dialect should follow vernacular linguistic isoglosses, not the diocesan and…

University quodlibets were open-microphone disputations held twice a year, in Advent and in Lent, where anyone could ask the master anything. The two sessions sat in different economic seasons: Advent fell at the close of the autumn term amid year-end accounting and…

Early medieval penitentials priced sins in time — days, quarantines, years of fasting — the way mints price value in coins. The conjecture is that penance values are genuinely denominational: they cluster on a small set of canonical quantities (7, 10, 40…

Medieval miracle collections record two great genres of wonder: the sick healed at the shrine, and the distant devotee — the drowning sailor, the chained prisoner — saved by invocation alone. The conjecture is that the mix is a strict function of…

Indulgences — remissions of penance measured in days and years — famously inflated across the later Middle Ages. The conjecture is that the inflation had exactly one source: canon law capped each bishop's grant at forty days, and that cap held, so…

Monks vowed to silence developed sign languages, and several houses wrote their sign lists down. The conjecture treats these lexicons as fossilized measurements of institutional complexity: a house's sign count should scale with the complexity of its material life — above all…

Confraternity statutes obliged members to recite set numbers of Paters and Aves for dead brethren — five here, thirteen there, thirty elsewhere, a diverse tariff landscape. The conjecture is that the spread of the rosary as a counting technology re-quantized these obligations:…

Byzantine monastic founders wrote typika — charters specifying, among much else, perpetual commemorations for themselves and their donors. Each generation added obligations; none subtracted its predecessors'. The conjecture is that this created a genuine liturgical debt crisis with a paper trail: as…

In Muslim Spain, Hebrew poets adopted Arabic quantitative meter — a scandal and a triumph — and wrote synagogue poetry with it. The conjecture is that the innovation's penetration into the liturgy was governed by halakhic status rather than by taste or…

Books of hours ended with suffrages — short memorials to chosen saints — and the choice tracked what owners feared. The conjecture turns two plague intercessors into a precision dating instrument: Sebastian's suffrage frequency should double within a generation after the Black…

Early medieval charters routinely ended by cursing violators — anathema, the fate of Judas, eternal fire — while later charters mostly dropped the curses. The conjecture is that the curse was a substitute enforcement technology whose use varied inversely with access to…

Four seasonal Marian antiphons closed the liturgical day, yet one — the Salve Regina — came to tower over the others in polyphonic settings, endowed services, and civic devotion. The conjecture locates the cause in lay money: testators and confraternities endowing evening…

This conjecture joins the heresiology of the 1270s condemnations to plain citation counting: the density of authorities in a scholastic article tracks institutional risk, not intellectual difficulty. On topics where a determination might attract censure, such as the eternity of the world…
