"Raphael Sanzio. (Ital. 1483-1520.) Urbino. The sistine madonna. 42 x 56. Original in the Royal Gallery, Dresden. Copied by Theodore Schmidt, director of that gallery, whose leisure time it occupied for five years. As a copy, it is as near perfection as may be. It is the third ever made from the original, which was the last picture wholly finished by Raphael. It was painted to be carried as a banner in processions, for the monks of the convent of St. Sisto, Piacenza. It was, however, made an altar piece in the church, where it remained more than two hundred years. In 1730 it was bought for the dresden gallery. The picture is called the sistine madonna, because in it St. Sisto (sixtus), the patron saint of the convent is on the virgin's left hand. St. Barbara is on the right."
