All the world was a symbol to the men of those Ages of Faith. The interlinked petals of the transept's northern rose meet in a symbol of the Divinity--a knot without beginning or end--the _forma universal_ visioned by Dante. There are Frenchmen who think that the splendid rose windows in their Gothic cathedrals suggested to the exile of Florence his conception of the empyrean. Heaven as Dante visioned it had neither roof of gold nor pillars of jasper, but was an expanded, supernal, white rose. Once the nave of Tours Cathedral was filled with late-Gothic windows, but storms wrecked many of them. Some of its glass has been set in a line of lights beneath the transept's north rose, XV-century panels representing members of the Bourbon Vendôme family, that was to mount the French throne with Henry IV. Jean Fouquet might have drawn them. Under the XVI-century rose in the west façade is another row of windows containing good portraits of art patrons as munificent as the Bourbons--the Laval-Montmorency family. All over France we find them as donors of beautiful things. The hour when Tours was an individual leader in art came during the late-Gothic development.[157] Then was finished the cathedral's nave, chapter house, library, cloister, and the psaltery with its pretty Renaissance stair. The cathedral canons, _Messires de la Gatienne_, sacrificed a forest for the nave's overroof. The elaborate Flamboyant façade was set up. Jean Papin was its architect, and Jean de Dammartin, fresh from Le Mans' transept, worked on it. It was begun under Archbishop Philippe de Coëtquis (1427-41), one of the learned men whom Charles VII summoned to interrogate Jeanne d'Arc. He pronounced her entirely sincere. In Tours Cathedral, April, 1429, knelt St. Jeanne for a solemn benediction before she went forth to accomplish her feat at Orléans. An artist of Tours made for her the banner she loved better than her sword. When Tours heard that she was taken prisoner, public prayers were ordered and a procession marched with bare feet, in penitential intercession for her deliverance. Charles VII had been married in Tours to his cousin Marie of Anjou, who was, says the modern student, more his incentive to patriotism than Agnes Sorel. The son of Charles, Louis XI, also was married in the cathedral of Tours, and preferred to live in the environs of the ancient ecclesiastic city. Under the saintly Archbishop Robert de Lenoncourt, installed here in 1488, were finished Tours' western portals. Their foliage is tormented, serrated, and deeply undercut, almost too prodigally and delicately sculptured for an exterior decoration. The entranceways are to-day shorn of their imagery, the statues having been shattered in 1562. In the Renaissance day the façade's twin towers were gracefully topped; _deux beaux bijoux_, Henry IV called the belfries of Tours.
