 As the monastery of Nivelles was under Irish discipline, the companions of Foillan were well received and lived side by side with the holy women, occupying themselves with the details of worship under the general direction of the abbess.Through the liberality of Itta, Foillan was enabled to build a monastery at Fosses-la-Ville, not far from Nivelles, in the province of Namur.After the death of Itta in 652, Foillan came one day to Nivelles and sang Mass, on the eve of the feast of Saint Quentin.
