Vitae Patrum

The Vitae Patrum (literally Lives of the Fathers, also called Lives of the Desert Fathers) is an encyclopedia of hagiographical writings on the Desert Fathers and Desert Mothers of early Christianity. The bulk of the original texts date from the third and fourth centuries.. The Lives that were originally written in Greek were translated into Latin between the fourth and the seventh century. An Italian vernacular translation was made by Dominican friar Domenico Cavalca from Pisa at the beginning of the fourteenth century.

A printed edition, edited by the Jesuit Heribert Rosweyde, was printed by Balthazar Moret in 1615. The book is a significant part of the much broader work, Acta Sanctorum.

The Vitae Patrum is based on extensive research by Rosweyde into all the available literature he could find on the early desert monastics. Hippolyte Delehaye described the work as "the epic of the origins of monasticism in Egypt and Syria, an epic unsurpassed in interest and grandeur." In the thirteenth century, a version of Vitae Patrum had been translated into Latin. It was such a popular book that numerous versions and editions were published, with extensive changes and variations in the stories. Rosweyde based his book on twenty-three different versions of those earlier books, studying, dating, and classifying all the different versions and changes.

Rosweyde's Vitae Patrum consists of ten books. Book I has the lives of sixteen saints under the title Vitae virorum and eleven saints under the title Vitae mulierum, beginning with St. Paul the Hermit and St. Anthony of the Desert, and including women saints such as Saint Mary the Harlot. Books II, Historia monachorum, and III, Verba seniorum (Sayings of the Elders), are attributed to Rufinus, who was later found to be only their translator. Book IV is a compilation of writings by Sulpicius Severus and John Cassian. Book V is another collection of Verba seniorum from Latin and Greek by Pelagius.
