§ 10. There is nothing in this scene, taken by itself, particularly interesting or impressive. The mountains are not elevated, nor particularly fine in form, and the heaps of stones which encumber the Ticino present nothing notable to the ordinary eye. But, in reality, the place is approached through one of the narrowest and most sublime ravines in the Alps, and after the traveller during the early part of the day has been familiarized with the aspect of the highest peaks of the Mont St. Gothard. Hence it speaks quite another language to him from that in which it would address itself to an unprepared spectator: the confused stones, which by themselves would be almost without any claim upon his thoughts, become exponents of the fury of the river by which he has journeyed all day long; the defile beyond, not in itself narrow or terrible, is regarded nevertheless with awe, because it is imagined to resemble the gorge that has just been traversed above; and, although no very elevated mountains immediately overhang it, the scene is felt to belong to, and arise in its essential characters out of, the strength of those mightier mountains in the unseen north.

§ 11. Any topographical delineation of the facts, therefore, must be wholly incapable of arousing in the mind of the beholder those sensations which would be caused by the facts themselves, seen in their natural relations to others. And the aim of the great inventive landscape painter must be to give the far higher and deeper truth of mental vision, rather than that of the physical facts, and to reach a representation which, though it may be totally useless to engineers or geographers, and, when tried by rule and measure, totally unlike the place, shall yet be capable of producing on the far-away beholder's mind precisely the impression which the reality would have produced, and putting his heart into the same state in which it would have been, had he verily descended into the valley from the gorges of Airolo.
§ 12. Now observe; if in his attempt to do this the artist does not understand the sacredness of the truth of _Impression_, and supposes that, once quitting hold of his first thought, he may by Philosophy compose something prettier than he saw, and mightier than he felt, it is all over with him. Every such attempt at composition will be utterly abortive, and end in something that is neither true nor fanciful; something geographically useless, and intellectually absurd.
