Viator of Bergamo was a 4th-century bishop who served as the second leader of the see in Bergamo. Following the leadership of Saint Narnus, he held his position as bishop from approximately 343 until his death in 370. During his career, he participated in the Council of Sardica to address theological disputes regarding Arianism. His contributions were significant enough that Saint Athanasius identified him as a co-author of the decree Apologia contra Arianus.
Life and career

Born in Brescia around 350, Viator became a prominent figure in the early church. He was a presbyter who rose to become the bishop of both Brescia and Bergamo. His involvement in the Council of Sardica between 342 and 343 allowed him to help shape ecclesiastical decrees intended to resolve doctrinal conflicts of his era.
Veneration and relics
The memory of this saint has persisted through many centuries, with his name recorded in litanies and calendars from the eleventh to the thirteenth centuries. Originally, his remains were kept in the crypt of a church dedicated to Saint Alexander. After that building was destroyed in 1561, his relics were moved to the church of San Vincenzo, which serves as the cathedral of Bergamo.
