Juvenal of Narni

Saint Juvenal (d. May 3, 369 or 377) is venerated as the first Bishop of Narni in Umbria. Historical details regarding Juvenal's life are limited. A biography of Juvenal of little historical value, written after the seventh century, states that Juvenal was born in Africa, was ordained by Pope Damasus I, was the first bishop of Narni, and was buried in the Porta Superiore on the Via Flaminia on August 7, though his feast day was celebrated on May 3. This Vita does not call him a martyr but calls him a confessor. but since 1969, he is no longer included in the General Roman Calendar.

His legend suggests that he saved Narni from both Ligurian and Sarmatian invaders by calling down a divine thunderstorm.

The construction of Juvenal's sepulcher in Narni is attributed to his alleged successor, St. Maximus (d. 416 AD). The author of the Life of Pope Vigilius (sixth century) in the Liber Pontificalis states that a monastery founded by Belisarius near Orte was dedicated to Juvenal. In 878, Juvenal's relics were taken to the Basilica di San Frediano in Lucca with those of Saints Cassius and Cassius' wife Fausta by Adalbert, Margrave of Tuscany, but all of the relics were returned to Narni two years later. The relics of Saint Cassius were built in a restored shrine later known as the Sacello di San Cassio. Juvenal's relics are said to have been hidden.

Fossano claims Juvenal as a patron and also claims to hold some of his relics, though these may belong to another saint of the same name.
