The architect, Louis Levau, employed by Foucquet, was not a beginner. He had already built "a house at the apex of the island of Notre-Dame,"[2] which is none other than the Hôtel Lambert,[3] the ingenious novelties of which were greatly admired. Especially noteworthy was the chamber of Madame de Torigny, on the second floor, which Le Sueur had decorated with a grace which recalls the mural paintings of Herculaneum. This chamber was called the Italian room, "Because," said Guillet de Saint-Georges, "the beauty of the woodwork and the richness of the panelling took the place of tapestry." Levau, born in 1612, was forty-three years of age when he signed the _ne varietur_ plan. We know little about the life of this man whose work is so famous. A document of the 23rd March, 1651,[4] describes him as "a man of noble birth, Councillor and Secretary to the King, House and Crown of France." He then lived in Paris, in the Rue du Roi-de-Sicile, with his wife and his three young children, Jean, Louis and Nicolas. Besides the Hôtel Lambert and the Château de Vaux, we are indebted to him for the design for the Collège des Quatre-Nations, now the Palace of the Institute; the Maison Bautru, called by Sauvai "La Gentille," and engraved by Marot; the Hôtel de Pons, in the Rue du Colombier (to-day the Rue du Vieux-Colombier), built for President Tambruneau; the Hôtel Deshameaux, which, according to Sauvai, had an Italian room; the Hôtel d'Hesselin in the He Saint-Louis; the Hôtel de Rohan, in the Rue de l'Université; the Château de Livry, since known as Le Rainey, built for the Intendant of Finances, Bordier; the Château de Seignelay; a château near Troyes; and the Château de Bercy.[5] We may add that Louis Levau, having become first architect to the King, succeeded Gamard in directing the works of the church of Saint-Sulpice, and that he, in his turn, was succeeded by Daniel Gillard in 1660.[6] Louis Levau died in Paris. His body was carried to the church of Saint-Germain-l'Auxerrois, his parish church, on Saturday, the nth October, 1670, as attested by the register of this church. There, under the above date, may be read: "On the said day was buried Messire Louys Levau, aged 57 or thereabouts, who died this morning at three o'clock. In his life a Councillor of the King in his Council, general Superintendent of His Majesty's buildings, first Architect of his buildings, Secretary to His Majesty and the House and Crown of France, etc., taken from the Rue des Fossés, from the ancient Hôtel de Longueville."[7] In the _Archives de l'Art français_ (Vol. I) there is a document relating to Louis Levau:
