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 a
De viris illustribus before he left
Avignon for Rome in 1338. Another of Petrarch's friends, Guglielmo Pastrengo, had two works on lives of famous men,
De viris illustribus and
De originibus. Petrarch's friend, Pastrengo, also wrote a work on
De viris illustribus and
De originibus. The previous historian's works of
De originibus are about the origins and definitions of geographical sites, peoples, and certain stone structures. Petrarch intended his work to be instructional for teaching moral righteousness. He found comfort in the misfortunes of Old Testament figures such as Jacob and Joseph. He showed to his fourteenth century readers the lessons of
common sense morality that could be learned from the ancient Roman leaders and Old Testament figures. He stressed these points over that of victories on the battlegrounds, which he considered as mere luck and incompetence of the enemies. He saw his duty of his work to be "describing illustrious men, not lucky ones." ==Footnotes==
