I am strongly of opinion that the Borgo picture was the original work, the Lyons one, for which he contracted to the monks of Cassino, March 6th, 1495, being either a somewhat hurried replica of it in which the master grew tired of the monotony of repetition, or else that it was a picture in which a certain amount of labour was left to assistants and pupils. There is an important study for three apostles, in the Uffizi, which was clearly prepared for the Borgo picture and not for the Lyons one, as, while closely resembling the former, it differs from the latter in one or two important details. This is not the accepted theory, I know, and it is one that will probably not meet with universal acceptance, but a careful comparison of the pictures leads me to a clear opinion in the matter. With regard to the pilaster saints the case is different. Those at the Vatican are all genuine work of the master and are extremely fine, and the same may be said of three of the five at Perugia, but two of them are not entirely Perugino's work, and bear traces of a pupil's hand. The three predella pictures on the other hand, which are at Rouen, are charming examples of the master's work, and are bathed in that wonderful golden sunlight which is so distinctive of his finest work. In each picture a strip of the foreground which was damaged in transit has had to be restored: in the "Adoration" it is the very slightest bit along the front of the whole picture; in the "Resurrection" it is a wider piece, embracing part of the feet of three of the sleeping soldiers and the edge of the stone slab on which the tomb rests; but in the third picture, the "Baptism," the damage is serious, as the foreground strip includes the feet of Our Lord and one foot of the Baptist. In all other respects these three panels are exquisite specimens of Perugino's fine and discriminative work.
