Read the full account

Petrarch selected, revised, and arranged letters to living friends as Rerum familiarium libri, a designed book rather than a raw inbox, circulating in his later decades (a conventional closing neighbourhood in the 1360s). Ventoux is one letter inside it, already stored separately.

Context

Humanist friendship is a network technology. Shared with Boccaccio, with Dionigi, with Nelli, with unnamed scribes. Cohesion here is learned Latin friendship, not a village. Some letters were rewritten for the book; that is why this is an edition-act, not a secret diary.

Shared responsibility is part of Familiares issued as a crafted public letter-book. Naming Petrarch does not delete co-authors, institutions, or later transmitters. The lag from 1366-01-01 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.

Why it matters

A public art of the letter is a cohesion path of high confidence and modest-to-moderate weight. It is also an elite gate: Latin. Mixed elite character is why the weight is not a ministry of education.

What the sources establish

The Latin Library at https://www.thelatinlibrary.com/petrarch.html (opens in a new tab) carries public Latin. Treccani at https://www.treccani.it/enciclopedia/francesco-petrarca/ (opens in a new tab) independently treats the letter collections as central works. Britannica restates the Familiares.

Established: a crafted Familiares letter-book in his lifetime. Not established: that every letter is an unrevised original, or a unique network coefficient. Distinct from Seniles and from Sine nomine. Rerum familiarium libri as designed friendship-book, 1360s close, not the invective without-name letters. Official locator https://www.thelatinlibrary.com/petrarch.html (opens in a new tab) is not independent locator https://www.treccani.it/enciclopedia/francesco-petrarca/ (opens in a new tab).

Later competitions, monuments, translations, UNESCO listings, museums, and adaptations are not converted into extra lifetime acts.

If a number is not in the two records named above, it is not supplied here.

Confidence is stated on the impact path, not hidden in adjectives. Familiares is not Liber sine nomine. Mixed effects of Familiares issued as a crafted public letter-book are separate paths.

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