While his predecessor had advised Aetherius to take the diocese, King Gontran named Priscus instead.
[1] There is little information about Priscus' character, no evidence either of indignity, or of particular pastoral zeal.
His metrical episcopal epitaph allows us to know that he came from the nobility and that he held political office before becoming a bishop.
Also present were the bishops Evantius of Vienne, Syagrius of Autun, Isice I of Grenoble, Isaac I of Valence, Eusebius of Mâcon, Agricola of Nevers and Veranus of Cavaillon.
Among the decisions, the sixth and last canon decided to open at the expense of the bishop a leprosarium in each city.
