# Liber sine nomine circulates as nameless invective against Avignon as Babylon

Date: 1358

## The fact

Liber sine nomine gathers letters that attack the Avignon papal court as a new Babylon, often with names suppressed. It is not the Familiares friendship-book and not a later Protestant pamphlet, though later readers used it that way.

## Context

Polarisation here is Avignon versus Rome, court versus a purified church-city. Shared with unnamed addressees. The author still held livings; that hypocrisy is why the benefice row exists. Confidence high on the text, medium on political effect.

The contribution type is direct. The attached driver is [political-polarization](/drivers/political-polarization). The welfare reading used in this dossier is worsening. That reading is an impact-path choice, not a property stored on the Fact itself.

## Evidence and sources

Latin Library at https://www.thelatinlibrary.com/petrarch.html and Treccani at https://www.treccani.it/enciclopedia/francesco-petrarca/ independently locate the nameless invectives. Britannica’s Avignon years supply the court context.

Official or archival record: The Latin Library — Petrarch (https://www.thelatinlibrary.com/petrarch.html; The Latin Library).

## Significance

Babylon-invective is a polarisation path of high confidence and moderate weight inside church politics. It is not a unique schism coefficient. Mixed: it also argues for a Roman see.

Shared responsibility is part of Liber sine nomine circulates as nameless invective against Avignon as Babylon. Naming Petrarch does not delete co-authors, institutions, or later transmitters. The lag from 1358-01-01 to any measured indicator is not treated as zero. Alternative explanations — weather, other armies, later statutes, or independent cultural change — remain live where the sources do not close them.
