Viator is traditionally considered the successor of Saint Narnus in that see.
[1] Viator attended the Council of Sardica (342–343), called to adjust the doctrinal and other difficulties of the Arian controversy.
[1] His name appears on calendars dating from the eleventh, twelfth, and thirteenth centuries; his name appears in a litany dating from the twelfth century.
When this church was demolished in 1561, Viator's relics, as well as those of Narnus, were translated to the church of San Vincenzo, today the cathedral of Bergamo, where they still rest today.
