The valley of roses was the favorite residence of the reigning counts. Here Thibaut IV, the most celebrated lyric poet of the Middle Ages, wrote his songs that wedded the art of the Midi troubadour with the salt of the northern trouvère. His son, Thibaut V, married the daughter of St. Louis and brought her in state to Provins, "_où ils firent leur entrée accompagnés d'une grande foison de barons_," wrote Joinville, who had helped to arrange the match. Thibaut V's heart is contained in a XIII-century monument now in the chapel of the Hôtel Dieu, which hospital was originally the ancient palace of the countesses of Champagne. Thibaut V and his wife died returning from the tragic last crusade of Louis IX. Their niece Jeanne married the king of France, and the prosperous days of Champagne ended when it merged its independence in the royal domain, for new regulations soon impaired the popularity of its famous fairs. It was Countess Jeanne of Navarre who persuaded her seneschal, Joinville, to write his reminiscences. In the days when Provins was a world center St. Quiriace church was begun about 1160 by Henry the Liberal, the reigning count who was warmest patron of John of Salisbury when the latter, forced to quit England, lived in Provins. Little more than the choir of St. Quiriace now remains. In the tympanum of a late-Gothic portal is a XIII-century image of Christ. The semicircular chevet is boxed in a square ambulatory on which open square eastern chapels. The shafts are banded with annulets. There is Romanesque feeling in the zigzag ornamentation on the heavy ribs; the round arch reigns in the triforium, although the pier arcades below are pointed. The choir shows a curious experiment in vaulting hardly to be called successful: three bays are embraced by the vault section of eight branches. St. Quiriace crowns the hilltop; in the lower town is St. Ayoul, whose portal sculpture (c. 1160) is of the same type as the three western doors at Chartres, as is the portal of St. Loup-de-Naud (Seine-et-Marne), close by.[68] Those who have fallen under the spell of Chartres' fascinating column statues will always study their sister images with interest.
