It appears to me that such conduct is no less absurd than if a plain man, giving a relation of real distress occasioned by an inundation accompanied with thunder and lightning, should, instead of simply relating the event, take it into his head, in order to give a grace to his narration, to talk of Jupiter Pluvius, or Jupiter and his thunderbolts, or any other figurative idea; an intermixture which, though in poetry, with its proper preparations and accompaniments, it might be managed with effect, yet in the instance before us would counteract the purpose of the narrator, and, instead of being interesting, would be only ridiculous. The Dutch and Flemish style of landscape, not even excepting those of Rubens, is unfit for poetical subjects; but to explain in what this ineptitude consists, or to point out all the circumstances that give nobleness, grandeur, and the poetic character, to style, in landscape, would require a long discourse of itself; and the end would be then perhaps but imperfectly attained. The painter who is ambitious of this perilous excellence must catch his inspiration from those who have cultivated with success the poetry, as it may be called, of the art; and they are few indeed. I cannot quit this subject without mentioning two examples which occur to me at present, in which the poetical style of landscape may be seen happily executed: the one is Jacob's Dream, by Salvator Rosa, and the other the return of the Ark from Captivity, by Sebastian Bourdon. With whatever dignity those histories are presented to us in the language of Scripture, this style of painting possesses the same power of inspiring sentiments of grandeur and sublimity, and is able to communicate them to subjects which appear by no means adapted to receive them. A ladder against the sky has no very promising appearance of possessing a capacity to excite any heroic ideas; and the Ark, in the hands of a second-rate master, would have little more effect than a common waggon on the highway: yet those subjects are so poetically treated throughout, the parts have such a correspondence with each other, and the whole and every part of the scene is so visionary, that it is impossible to look at them without feeling, in some measure, the enthusiasm which seems to have inspired the painters. By continual contemplation of such works, a sense of the higher excellencies of art will by degrees dawn on the imagination; at every review that sense will become more and more assured, until we come to enjoy a sober certainty of the real existence (if I may so express myself) of those almost ideal beauties; and the artist will then find no difficulty in fixing in his mind the principles by which the impression is produced; which he will feel and practise, though they are perhaps too delicate and refined, and too peculiar to the imitative art, to be conveyed to the mind by any other means.
