Saint Juvenal 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. The martyrologies of Florus of Lyon and Ado describe Juvenal as a bishop and confessor rather than as a martyr.
