Guido, from want of choice in adapting his subject to his ideas and his powers, or from attempting to preserve beauty where it could not be preserved, has in this respect succeeded very ill. His figures are often engaged in subjects that require great expression; yet his Judith and Holofernes, the daughter of Herodias with the Baptist's head, the Andromeda, and some even of the Mothers of the Innocents, have little more expression than his Venus attired by the Graces. Obvious as these remarks appear, there are many writers on our art, who, not being of the profession, and consequently not knowing what can or cannot be done, have been very liberal of absurd praises in their descriptions of favourite works. They always find in them what they are resolved to find. They praise excellencies that can hardly exist together; and, above all things, are fond of describing, with great exactness, the expression of a mixed passion, which more particularly appears to me out of the reach of our art. Such are many disquisitions which I have read on some of the Cartoons and other pictures of Raffaelle, where the critics have described their own imaginations; or, indeed, where the excellent master himself may have attempted this expression of passions above the powers of the art, and has, therefore, by an indistinct and imperfect marking, left room for every imagination, with equal probability to find a passion of his own. What has been, and what can be done in the art, is sufficiently difficult; we need not be mortified or discouraged at not being able to execute the conceptions of a romantic imagination. Art has its boundaries, though imagination has none. We can easily, like the ancients, suppose a Jupiter to be possessed of all those powers and perfections which the subordinate deities were endowed with separately. Yet, when they employed their art to represent him, they confined his character to majesty alone. Pliny, therefore, though we are under great obligations to him for the information he has given us in relation to the works of the ancient artists, is very frequently wrong when he speaks of them, which he does very often, in the style of many of our modern connoisseurs. He observes, that in a statue of Paris, by Euphranor, you might discover, at the same time, three different characters; the dignity of a Judge of the Goddesses, the Lover of Helen, and the Conqueror of Achilles. A statue, in which you endeavour to unite stately dignity, youthful elegance, and stern valour, must surely possess none of these to any eminent degree. From hence it appears, that there is much difficulty, as well as danger, in an endeavour to concentrate, in a single subject, those various powers, which, rising from different points, naturally move in different directions.
