"Raphael Sanzio. (see no. 553.) The transfiguration. 43 x 43. Original in the Vatican, at Rome. This is considered Raphael's masterpiece. At the foot of the mountain is a multitude, among whom are the disciples trying to cast an evil spirit out of a boy. On the mountain, Christ is transfigured before Peter, James and John, whom he took apart on that occasion. It has been strenuously contended, and even unconditionally confirmed, that Raphael only painted the upper half of this picture. There does appear to be conclusive ground for such an assumption. Raphael did not, it is true, live to entirely complete it, the few parts remaining unfinished at his death having been painted by his pupil, Giulio Romano, but the weight of the evidence is greatly on the side of Raphael having designed the whole picture as it is, and having painted all but a few subordinate parts of it."
