Frontinian of Alba

Frontinian of Alba was, according to tradition, a deacon born at Carcassonne in present-⁠day France. He went on pilgrimage to Rome with Cassian, who was of Irish origin. On the way back, the deacon Frontinian stopped at Alba Pompeia in Italy to preach the Gospel. There he and his companion were martyred.

There are several traditions about Frontinian and his companion. A monastery was built on the spot where the monks died. Frontinian is counted among the patron saints of the city of Alba. A painting in the cathedral, in the chapel of Saint Tebaldo, shows him with a knife lodged in his head. According to the source he lived in the fourth century.

Piero Bargellini gives 22 August as his day of commemoration; the calendar is not stated. He is honoured as a saint of the undivided Church, with no synodal canonization shown in the source.
