St Cassius (29th June)
St Cassius became Bishop of Narni in 537. He died at some time after 558 and was interred beside his wife Fausta, who had predeceased him in the oratory of San Giovenale, later incorporated into the Duomo and known as the Sacello di San Cassio (shrine of St Cassius) His relics were stolen in 878, but returned to Narni in 880. They were translated to the current the altar in this shrine in 1679.
St Juvenal (3rd May)
St Juvenal, the first bishop of Narni, died in ca. 376 and was interred on the site of the present Duomo (San Giovenale), which is dedicated to him. An oratory, later known as the Sacello di San Cassio, was built over his grave soon after. His relics were stolen and taken to Lucca in 378, but returned to Narni soon after and buried in the rock below the Sacello di San Cassio. They were rediscovered in 1642 and translated to a new site under the high altar of the Duomo.
Blessed Lucy of Narni (15th November)
Lucy Broccadelli, who was born in Narni, became a Dominican tertiary at Viterbo, and it was there that she received the stigmata in 1496. This led to an investigation by the Inquisition, and she was finally vindicated. Duke Ercole I d' Este built a new convent for her at Ferrara, and she died there in 1544. Her cult was confirmed for Narni and Viterbo in 1710, when some of her relics were returned to Narni from Ferrara. The rest of her relics followed in 1935 and are now housed in a reliquary on the altar of the Cappella della Beata Lucia in the Duomo.
Blessed Valentine of Narni (feast ?)
Blessed Valentine was born in Narni in the 14th century and seems to have given all of his goods to San Francesco there when he joined the Franciscan Order. According to an inscription in San Francesco, Assisi,
he had been a “phisicus”(natural philosopher) before he joined the Franciscan Order, but that he decided always to remain a layman (rather than to become ordained, as his education would have normally dictated). He died at the Eremo dei Carceri, outside Assisi in 1378, and many miracles occurred at his tomb.
