parallel of De Viris Illustribus. Petrarch conceived his first plan for De viris illustribus of biographies of illustrious men of Jewish, oriental, Greek and Roman famous figures in 1337-38. He wrote up his list of "Illustrious Men" from Adam to Hercules and Romulus to Titus in 1337-38 about the same time as he was writing up the Africa. Petrarch's earliest reference to writing a series of biographies of Lives can be found in the third book of his work Secretum which was originally written up around 1337. St. Augustine speaks to Petrarch Petrarch went from these Lives of "Illustrious Men" into his work on the Africa using the research of De viris illustribus as the bases. Petrarch was preoccupied with this idea of a series of biographies of Lives of ancient heroes of generals and statesmen for almost forty years. There were several plans of De viris illustribus. In 1348-49 Petrarch made a larger version of Lives. Petrarch writes a letter to Luca Cristiani in 1349 concerning these Lives for De viris illustribus that he was doing in the valley at Vaucluse in France; Petrarch mentions in letters from Vaucluse around 1350 that he was working on a De viris illustribus that was wholly committed to those who were illustrious "from every country" and that he was "bringing together illustrious men from all lands and centuries." This is known to scholars as an "all-ages" plan. Petrarch added the "bio" of Julius Caesar, De gestis Cesaris ("On the Deeds of Caesar"), later as the twenty-fourth and last character of the Roman version finished about 1364 (fourteenth reigning year of John the Good) as an afterthought to his original "Famous Men." He wanted to depict events that were controlled by the Roman leaders, not events that happened by luck or fortune. He wanted to be a critical historian and convey these illustrious men in dignity. For these reasons he is considered the first historian of the Renaissance. Plans Petrarch worked on various "plans" and versions of De viris illustribus. He was not only influenced by ancient historians like Livy and Valerius Maximus, but by other historians of his time period that were working on similar ideas. In the early part of the fourteenth century in northern Italy it was fairly commonplace among historians to write a series of biographies on famous men. A friend of Petrarch's, Giovanni Colonna, authorized his version of
