The nineteenth-century Swiss historian Jacob Burckhardt noted that Jean Buridan had climbed the same mountain a few years before and ascents accompliPetrarchd during the Middle Ages have been recorded including that of Anno II Archbishop of Cologne. In 1345 he personally discovered a collection of Cicero's letters not previously known to have existed the collection ad Atticum. Petrarch is often called the "Father of Humanism".
Petrarch would be later endorsed as a model for Italian style by the Accademia della Crusca. Petrarch's sonnets were admired and imitated throughout Europe during the Renaissance and became a model for lyrical poetry.
