Jean Mabillon followed an early tradition that the abbey had been founded by Saint Columbanus, which would place the foundation in the late sixth century.
[3] It was refounded during the reign of Louis the Pious in the early ninth century by Saint Eutice, probably a disciple of Benedict of Aniane, who was revitalizing and reordering the Benedictine communities of the Gauls.
In 817, when Emperor Louis at Aachen divided the monasteries in his lands into three categories, monasterium Balma was one of only twelve that owed him annual subsidies.
[7] After the desolation of Burgundy by the Normans, 887—899, once again it had fallen into such desuetude, that its second refounding abbot,[8] Berno, who was later called from Baume to found Cluny Abbey in 910, is generally credited with being its founder, about 890.
About 909, Odo with his noble companion Adegrin, found Baume and became a monk, priest, and then superior of the abbey school, bringing with him a library of 100 books.
