The royal authority waxed and waned, the turbulent nobles exhausted themselves in war, in struggles amongst themselves and against the king, but the wealth and power of the Church steadily increased. Occasionally only, when its interference was too flagrantly unjust, its authority was defied. The first Capétiens, like the first Carlovingians, whether from motives of self-interest or sincere faith, were its faithful allies. Hugues Capet liked better to wear his cope as Abbot of Saint-Martin de Tours than his crown, and he restored to the Church several abbeys which he possessed. His son, Robert the Pious, was almost a saint, and the princes of this dynasty, on the whole, merited the title which Rome gave them, of "eldest sons of the Church." Their piety was not altogether without reward: the bishops of the Ile-de-France and the abbots, chiefs of the abbeys founded by royal grace, brought more than once not only earthly weapons but a spiritual one, that of excommunication, to the defence of the sovereign. Robert's first care, after his accession to the throne in 996, was to rebuild the church of Saint-Germain l'Auxerrois and the monastery of Saint-Germain-des-Près, which had been destroyed by the Northmen. He also erected in his palace a chapel dedicated to Saint Nicolas, which, in 1154, entirely restored, became the Sainte-Chapelle. He washed the feet of the poor, he fed, it is said, sometimes a thousand of them a day; nothing was too sacred for them, neither the silver ornaments of his lance nor the gold fringe of his robe. He was constant in his attendance on the church services, he composed hymns, himself, which were long retained. Nevertheless, having espoused his cousin Berthe, he found himself excommunicated by the Pope, Gregory V. Among the earliest works of the painter Jean-Paul Laurens, long in the Luxembourg, is a graphic presentation of this unhappy couple, clinging to each other in the poor, bare splendor of the very early mediæval throne-room, the overturned great tapers of the excommunication service on the floor before them, the smoke rising like anathema, and the last of the implacable ministers of the Church departing through the open doorway. Every one deserted them, as though plague-stricken; only two poor domestics remained to serve them, and they purified by fire every vessel from which the unhappy monarch had taken food or drink. But Berthe was _enceinte_, and the king loved her, and so clung to her and would not obey. One morning as he went to pray, according to his custom, at the door of the church of Saint-Barthélemy, into which he was forbidden to enter, Abbon, Abbé de Fleury, followed by two women of the palace, carrying a great silver-gilt plate covered with a linen cloth, approached him, and announced that Berthe had been delivered. Then he uncovered the plate: "See!" he exclaimed, "the effects of your disobedience to the decrees of the Church, and the seal of anathema on the fruit of your guilty love!"
