Ado or Adon of Vienne (Latin: Ado or Adonis Viennensis; d. 16 December 874), was archbishop of Vienne in Lotharingia from 850 until his death. He belonged to a prominent Frankish family and spent much his early adulthood in Italy. Several of his letters are extant and reveal their writer as an energetic man of wide sympathies and considerable influence. Ado's principal works are a Martyrologium, and a chronicle, Chronicon sive Breviarium chronicorum de sex mundi aetatibus de Adamo usque ad annum 869.
Born into a noble family, he was sent as a child to Sigulfe, abbot of Ferrieres, for his education. He then went to Marcward, Abbot of Prüm near Trier, for his education. After the death of the abbot in 853, Adon went to Rome where he stayed for nearly five years, and then in Ravenna. The Archbishop of Lyon, Remy, gives the parish of Saint-Romain near Vienna. He was elected the following year archbishop of Vienna and dedicated in August or September 860, despite opposition from Girart Count of Roussillon and his wife Berthe.
He participated in the council of Tousy, near Toul in Lorraine, 22 October 860, and held the 1st council of Vienna in 870. After his death 16 December 876, his body was buried in the church of the Apostles, now called St. Peter's Church, the ordinary place of burial of the archbishops of Vienna. He has a feast day celebrated on 16 December.
Ado's chronicle is based on that of Bede, with which he combines extracts from the ordinary sources, forming the whole into a consecutive narrative founded on the conception of the unity of the Roman Empire, which he traces in the succession of the emperors, Charlemagne and his heirs following immediately after Constantine VI and Irene. "It is," says Wattenbach, "history from the point of view of authority and preconceived opinion, which exclude any independent judgment of events."
Ado wrote also a book on the miracles (Miracula) of St. Bernard, archbishop of Vienne (9th century), published in the Bollandist Acta Sanctorum; a life or Martyrium of St. Desiderius, bishop of Vienne (d. 608); and a life of St. Theudericus, abbot of Vienne (563).
