There is extant a work known as "Libellus precum", which was written by two Luciferian clergy called Faustinus and Marcellinus. Jerome discusses Lucifer and his supporters in his polemic "Altercatio Luciferiani et orthodoxi" ("Altercation of a Luciferian and an Orthodox"), as well as describing the bishop's career in "De Viris Illustribus" (chapter 95).
