Familiares 4.1, addressed to the Augustinian Dionigi, narrates an ascent of Mont Ventoux with Petrarch’s brother Gherardo, a random opening of Augustine’s Confessions, and a turn from landscape to interior. In the causal graph this event strengthens Digital Learning Access, a driver that weakens Learning Poverty Rate (low- and middle-income countries) — an improving welfare path.

Familiares 4.1, addressed to the Augustinian Dionigi, narrates an ascent of Mont Ventoux with Petrarch’s brother Gherardo, a random opening of Augustine’s Confessions, and a turn from landscape to interior.

Context

The climb may be partly literary. That possibility is why confidence is medium on the hike and high on the existence of the letter as a humanist set-piece. Shared with Gherardo and with Augustine as quoted book. It is not a welfare fact about Laura. Later Romantic alpinism is reception.

Why it matters

Teaching a reader to turn from view to book is an education path of modest weight. It does not measure mountain tourism. Mixed: if the letter is back-dated, the day is a literary date, already flagged.

What the sources establish

The Latin Library’s Petrarch page at https://www.thelatinlibrary.com/petrarch.html (opens in a new tab) locates public Latin letters. Britannica at https://www.britannica.com/biography/Petrarch (opens in a new tab) independently treats the Ventoux letter as a famous self-accounting. Different URLs.

Established: a letter dated 26 April 1336 on Ventoux and Augustine. Not established: a unique path up the mountain or that every detail is reportage. Later printings are carriers. Familiares 4.1 to Dionigi; brother Gherardo; Confessions opened at random. Official locator https://www.thelatinlibrary.com/petrarch.html (opens in a new tab) is not independent locator https://www.britannica.com/biography/Petrarch (opens in a new tab).

Confidence is stated on the impact path, not hidden in adjectives. Ventoux is not the 1341 crown. Mixed effects of Letter on the ascent of Mont Ventoux, dated 26 April 1336, to Dionigi da Borgo San Sepolcro are separate paths.

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

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

Shared responsibility is part of Letter on the ascent of Mont Ventoux, dated 26 April 1336, to Dionigi da Borgo San Sepolcro. Naming Petrarch does not delete co-authors, institutions, or later transmitters. The lag from 1336-04-26 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.
