Many converts won over by him to the cause of God were gathered into several double monasteries, of religious men and women, in which the monks served the nuns and were subject to the abbess, in order to honor the Blessed Virgin St. Mary. Nuccio thus (1101) founded the Order of Fontevrault (q.v.), from the place where the first foundation was made, under the patronage of the Virgin. He died at Orsan while visiting the houses he had founded.
