Although three abbeys were the happy possessors of the remains of Blanche of Castille (Maubuisson, Lys, and Saint-Corentin-lez-Mantes), no tomb exists of the sweet mother of S. Louis.[46] Upon the monument at Maubuisson the queen was attired in the habit of the Cistercian order, which she assumed in her last moments; the crown was placed over the veil, the royal robes over the nun's habit, and so she passed away, and was thus buried. In 1793 various tombs, armorial bearings, and the like _aliments de l'orgueil_, were transported from Maubuisson to Pontoise; some were broken, some burnt; golden vessels and silver saints were thrust into the melting-pot; and Blanche of Castille, with the help of a prince perhaps, or a warrior, became transformed into an instrument of war. But the museum of the Petits-Augustins wanted an effigy of the mother of Monsieur Saint Louis; and so they set up a black marble image of Catherine de Courtenay, empress of Constantinople and wife of Charles of Valois, who had lately, and all alone, journeyed from Maubuisson; and, thinking it a joke to turn a black empress into a white queen, they wrote upon the slab, in 13th century characters, that it was the true monument of _Madame la royne Blanche mere de Monsieur Saint Loys_. After twenty years Madame Catherine-Blanche became divorced from her other half, and the white queen faded away in favour of the black empress. One of the most beautiful tombs is that of Philippe, the brother of S. Louis, which was formerly at Royaumont. The prince lies upon a sarcophagus, round which are niches filled with little figures of monks, bishops, and angels, full of character and expression. One of these represents a king: "On y voyait le cercueil de Louis porté par les barons de France et par le roi d'Angleterre.[47] Une figure couronnée porte sur l'épaule un des bâtons; c'est le roi anglais"[48]--proving the sovereignty of France over England. There is a curious engraving by Boulogne representing this procession. The church is in the distance; a string of monks are zigzagging across the plain, and in the foreground we see this crowned head and others bearing the reliquary; behind are bishops; the whole in the grandiose style of the 17th and 18th centuries--drapery flying in the wind, bishops and monks prancing, and all the faces turned to the spectator. S. Louis had always held the abbey in most respectful esteem. He visited it before he started upon his various expeditions; and in 1267, when he had conferred the order of chivalry upon his son Philippe and sixty other young noblemen, he rode to S. Denis on horseback to implore the blessing of God, accompanied by a large concourse of courtiers and princes. The monuments of the battle of Bouvines came from the church of S. Catherine-du-Val-des-Écoliers. They are incised stones, coloured and gilt, bearing the following inscriptions:--
