# At Verona in 1345 Petrarch finds Cicero’s letters to Atticus as received

Date: 1345

## The fact

In 1345 at Verona Petrarch reports discovering a manuscript of [Cicero](/people/cicero)’s letters to Atticus (and related correspondence), which he copied and which reshaped his image of the Roman letter as a humanist genre. It is not Liège 1333 and not a later Loeb.

## Context

A chapter library in Verona is not Petrarch’s private desk. Shared with keepers. The letters showed a Cicero who was not only a philosophical statue. Later print culture spread the text; he did not typeset 1470. Year-level date.

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

## Evidence and sources

Britannica at https://www.britannica.com/biography/Petrarch independently records the Verona discovery of Cicero’s letters. Vatican Library at https://www.vaticanlibrary.va/ is the archival neighbourhood of the Latin letter tradition. Treccani restates the 1345 find.

Official or archival record: Biblioteca Apostolica Vaticana — home (https://www.vaticanlibrary.va/; Biblioteca Apostolica Vaticana).

## Significance

Recovering Atticus-letters is a data path of high confidence in the biographical tradition and substantial cultural weight inside humanism, still modest as a macro indicator. It is not GDPR and not a unique byte-count.

Shared responsibility is part of At Verona in 1345 Petrarch finds Cicero’s letters to Atticus as received. Naming Petrarch does not delete co-authors, institutions, or later transmitters. The lag from 1345-01-01 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.

## What is established and what is not

Established as received: 1345 Verona find of Cicero’s letters. Not established: a unique surviving autograph of Petrarch’s copy in this date field. Distinct from Pro Archia. Ad Atticum at Verona, 1345, cathedral book into a working copy. Different city, different Cicero instrument from Liège. Official locator https://www.vaticanlibrary.va/ is not independent locator https://www.britannica.com/biography/Petrarch. Later Italian nationalism and UNESCO files are not this lifetime instrument.
