Godomar and Sigismund were kings of Burgundy. Sigismund converted from Homoian to Nicean creed, probably instigated by Bishop Avitus of Vienne. This could be part of the reason why Abbot and Presbyter Avitus advocated to Chlodomer to spare his life.
Gregory recalled this story himself when addressing the bishops present at the Fourth Council of Paris (AD 577); Avitus is referred to as a priest (sacerdos) (see Histories V.18).
Gregory of Tours in his Glory of the Confessors 97 mentions that Avitus was abbot of the monastery in the pagus Pertensis (La Perche) near Chartres, see [xxxxxxxxxxxxx">xxxxxxxxxxxxx].
