 Balthild is reported to have established the monastery first under the Rule of Saint Columbanus, then later adopted the Rule of Saint Benedict, although recent scholars, including Moyse and Dierkens, have warned against assumptions that the Rule was a firmly entrenched system.According to the "New Catholic Encyclopedia", the abbey represented a step in the progress of Celtic Christianity into Burgundy, especially in its admittance of monks.In any case, Balthild exerted control by appointing her own choice of abbess, Bertila.
