In the same manner he has given more animation to the figure of Sergius Paulus, and to that which is introduced in the picture of St. Paul preaching, of which little more than hints are given by Masaccio, which Raffaelle has finished. The closing the eyes of this figure, which in Masaccio might be easily mistaken for sleeping, is not in the least ambiguous in the Cartoon: his eyes, indeed, are closed, but they are closed with such vehemence, that the agitation of a mind _perplexed in the extreme_ is seen at the first glance; but what is most extraordinary, and I think particularly to be admired, is, that the same idea is continued through the whole figure, even to the drapery, which is so closely muffled about him, that even his hands are not seen; by this happy correspondence between the expression of the countenance, and the disposition of the parts, the figure appears to think from head to foot. Men of superior talents alone are capable of thus using and adapting other men's minds to their own purposes, or are able to make out and finish what was only in the original a hint or imperfect conception. A readiness in taking such hints, which escape the dull and ignorant, makes, in my opinion, no inconsiderable part of that faculty of the mind which is called Genius. It often happens that hints may be taken and employed in a situation totally different from that in which they were originally employed. There is a figure of a Bacchante leaning backward, her head thrown quite behind her, which seems to be a favourite invention, as it is so frequently repeated in basso-relievos, cameos, and intaglios; it is intended to express an enthusiastic, frantic kind of joy. This figure Baccio Bandinelli, in a drawing that I have of that Master of the Descent from the Cross, has adopted (and he knew very well what was worth borrowing) for one of the Marys, to express frantic agony of grief. It is curious to observe, and it is certainly true, that the extremes of contrary passions are, with very little variation, expressed by the same action. If I were to recommend method in any part of the study of a Painter, it would be in regard to invention; that young Students should not presume to think themselves qualified to invent till they were acquainted with those stores of invention the world already possesses, and had by that means accumulated sufficient materials for the mind to work with. It would certainly be no improper method of forming the mind of a young artist, to begin with such exercises as the Italians call a _Pasticcio_ composition of the different excellencies which are dispersed in all other works of the same kind. It is not supposed that he is to stop here, but that he is to acquire by this means the art of selecting, first, what is truly excellent in Art, and then, what is still more excellent in Nature; a task which, without this previous study, he will be but ill qualified to perform.
