Grisaille Panel ca. 1320-30 French The five panels assembled here come from at least four different lancets of the choir windows at Saint-Ouen at Rouen. They incorporate three different patterns of stylized leaves and tendrils, one with silver-stained blossoms, and three different strapwork designs in four combinations. All are known to have originated in this glazing program. The botanical theme is continued in the border pattern and in three of the central bosses or fermaillets. The combination of grisaille, silver stain, and colored glass is typical of fourteenth-century French stained glass.. Grisaille Panel. French. ca. 1320-30.
