The Vita patrum Iurensium ("Life of the Jura Fathers")[1] is an anonymous Latin biographical trilogy composed around 520.
It is a hagiographical work describing the lives of Romanus, Lupicinus and Eugendus, the founding abbots of the Jura Mountain monasteries of Condat, Saint-Lupicin and Romainmôtier, respectively.
[3] In his own words, the author of the Vita, who knew Eugendus personally, aimed to "reproduce faithfully...—according to what I saw there with my own eyes or received from the tradition of the elders—the deeds, the way of life and the rule of the esteemed fathers of the Jura Mountains".
[5] Gérard Moyse and Ian Wood have ventured that the anonymous author was Viventiolus, a priest at Condat before he became bishop of Lyon.
He says that Marinus, abbot of Lérins, had requested a copy of the Institutes he wrote for the community of Acaunus.
