To such extraordinary powers as were possessed by both of those Artists, we cannot refuse the character of Genius; at the same time, it must be acknowledged, that it was that kind of mechanic Genius which operates without much assistance of the head. In all their works, which are (as might be expected) very numerous, we may look in vain for anything that can be said to be original and striking; and yet, according to the ordinary ideas of originality, they have as good pretensions as most Painters; for they borrowed very little from others, and still less will any Artist, that can distinguish between excellence and insipidity, ever borrow from them. To those men, and all such, let us oppose the practice of the first of Painters. I suppose we shall all agree, that no man ever possessed a greater power of invention, and stood less in need of foreign assistance, than Raffaelle; and yet, when he was designing one of his greatest as well as latest works, the Cartoons, it is very apparent that he had the studies which he had made from Masaccio before him. Two noble figures of St. Paul, which he found there, he adopted in his own work: one of them he took for St. Paul preaching at Athens; and the other for the same Saint when chastising the sorcerer Elymas. Another figure in the same work, whose head is sunk in his breast, with his eyes shut, appearing deeply wrapt up in thought, was introduced amongst the listeners to the preaching of St. Paul. The most material alteration that is made in those two figures of St. Paul is the addition of the left hands, which are not seen in the original. It is a rule that Raffaelle observed (and, indeed, ought never to be dispensed with), in a principal figure, to show both hands; that it should never be a question, what is become of the other hand. For the sacrifice at Listra, he took the whole ceremony much as it stands in an ancient Basso-relievo, since published in the ADMIRANDA. I have given examples from those pictures only of Raffaelle which we have among us, though many other instances might be produced of this great painter's not disdaining assistance; indeed, his known wealth was so great, that he might borrow where he pleased without loss of credit. It may be remarked, that this work of Masaccio, from which he has borrowed so freely, was a public work, and at no farther distance from Rome than Florence; so that if he had considered it a disgraceful theft, he was sure to be detected; but he was well satisfied that his character for Invention would be little affected by such a discovery; nor is it, except in the opinion of those who are ignorant of the manner in which great works are built.
