That Raffaello in his last years, and when at the height of his celebrity, did exchange drawings with Albert Durer, is attested by the biographers of both: and that the design here described is one of that number, is incontestably proved, not only by the peculiarity of style, the elegance and facility of outline, the characteristic contrast of solid and muscular parts, but by the identity of the handwriting with the manuscripts of Albert still existing at Nürnberg, his native city. I therefore think it no improbable conjecture to suppose that Raffaello, by transmitting this specimen of his hand to Albert, intended to make him sensible of the difference between imitating Nature and dryly copying a model, and so impress him with the necessity of contrasting his outline according to the different texture of the parts in the bodies before him. This interesting leaf is one foot three inches three lines in height, and ten inches eight lines in width, Vienna measure; and in perfect preservation. II. This design differs in nothing from the well-known picture of the Transfiguration, but the absolute nudity of all the figures. That Raffaello was accustomed to sketch in naked outlines, may be known from most collections that possess something of his hand; but perhaps none but this may be able to produce a design, of a numerous and complete composition, in which every figure is rendered with anatomical correctness and finished chiaroscuro. Another singularity of this important leaf is, the characteristic disparity of execution in the figures; for though all are drawn with the pen, and on the first glance seem hatched in one uniform manner, it soon appears on close inspection, that they cannot have been produced by the same hand. The figures of the three Disciples on the Mount, especially the foreshortened one, are treated with that spirited facility and confident decision which always mark the pen of Raffaello. Those of the Saviour and the collateral prophets, though drawn with less precision and contours here and there, by repeated strokes, corrected, still exhibit on the whole the same spirit, facility, and confidence of hand. Of the actors below, the figure of John, with hands crossed on his breast, and the three next to him have the same Raffaellesque characteristics, and so the whole of the females kneeling on the foreground; but of the adjoining apostle, with the book in his hand, the projected leg and foot are absolutely out of drawing; whilst the Demoniac and his father, with all the remaining figures, drawn by mere practice, without a symptom of the master spirit, give palpable proofs of a different hand.
