De Viris Illustribus (Jerome) De Viris Illustribus ("On Illustrious Men") is a collection of short biographies of 135 authors, written in Latin, by the 4th-century Latin Church Father Jerome. He completed this work at Bethlehem in 392-3 CE. The work consists of a prologue plus 135 chapters, each consisting of a brief biography. Jerome himself is the subject of the final chapter. A Greek version of the book, possibly by the same Sophronius who is the subject of Chapter 134, also survives. Many biographies take as their subject figures important in Christian Church history and pay especial attention to their careers as writers. It "was written as an apologetic work to prove that the Church had produced learned men." The book was dedicated to Flavius Dexter, who served as high chamberlain to Theodosius I and as praetorian prefect to Honorius. Dexter was the son of Saint Pacianus, who is eulogized in the work.

Lucius Petronius Taurus Volusianus Volusianus was a Roman citizen, apparently of equestrian origins, whose career in the Imperial Service in the mid-Third Century AD carried him from a relatively modest station in life to the highest public offices and senatorial status in a very few years. He may have secured his first appointments before the Licinian Dynasty - (Valerian and his son Gallienus) - acceded to the Empire in 253 AD, but it was in the course of their reign that his upward progress achieved an almost unprecedented momentum and the second factor seems to have been a consequence of the first. The nature of his relationship to the Licinii is uncertain, but it seems likely that a common origin in the Etruscan region of central Italy predisposed Gallienus at least in his favour and he seems to have been that prince's most trusted servant and adviser during the period of his sole reign - 260(?)-268 AD.
