Roman historian Cornelius Nepos (99 - 24 BC) was a friend of Pomponius Atticus, Cicero, and Catullus. His only surviving work is a collection of biographies, mostly from a lost larger work, De viris illustribus [on illustrious men].
Modeled in a similar short biography fashion to that of Plutarch's Lives, the general concept was to compare the lives of great Roman and non-Roman leaders. Nepos wrote in a very popular, clear and readable Latin, but his work seemed to focus on style more than historical accuracy.
