Liber sine nomine circulates as nameless invective against Avignon as Babylon

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. That reading is an impact-path choice, not a property stored on the Fact itself.

Why it matters

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.

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.
