In 1106, Paschal II approved the Order and in Blessed Robert's lifetime some five thousand gathered at Fontevrault. Abbot Suger, who was a young student at that time near the new abbey, testified to the edification it gave. A sermon by the Blessed Robert converted the fair Bertrada de Montfort, who had quitted her ignoble husband, Fulk IV of Anjou, to marry Philip I, king of France, which illegal union kept churchmen busy during sixteen years; she callously brought her second master to visit her first. The fight which Rome waged to preserve monogamy in western Christendom deserves the highest praise. Bertrada died the second abbess of Fontevrault. The historic names of France compose the list of abbesses. The young widow of the only son of Henry I of England retired here, after the loss of the White Ship, and her father, Fulk V of Anjou, came to visit her as he quitted his career in Europe to take up his new role as king of Jerusalem. Margaret of Burgundy, the builder of Tonnerre's hospital hall, and second wife of Charles d'Anjou, St. Louis' brother, was educated at Fontevrault by her aunt the abbess. About 1500 Abbess Renée de Bourbon built the Renaissance cloister. To-day the famous house serves as a state prison. Fontevrault church played a part in the Gothic story. Its earliest cupola, over the transept-crossing, differs from those over the nave in that its base is not distinct from its dome. Angers copied it in its churches of St. Nicholas and St. Martin, and so did Saumur in St. Pierre. When in 1119 Calixtus II dedicated Fontevrault, the church consisted of the present choir and the transept. During the first quarter of the XII century the aisleless nave was spanned by four cupolas on clearly defined pedestals. Perhaps from Angoulême Cathedral came the fashion of domes on pendentives, after some Fontevrault monks had gone on legal business, in 1117, to the capital of Angoumois.
