The landscape is another type of unfettered composition. It was of course to be expected that in pictures without action there should be little suggestion of attention or of direction of movement. But the most remarkable point is the presence of vista in practically every example. It is, of course, natural that somewhere in almost every picture there should be a break to show the horizon line, for the sake of variety, if for nothing else; but what is significant is the part played by this break in the balancing of the picture. In about two thirds of the examples the vista is inclosed by lines, or masses, and when near the centre, as being at the same time the "heaviest" part of the picture, it serves as a fulcrum or centre to bind the parts—always harder to bring together than in the other types of pictures—into a close unity. The most frequent form of this arrangement is a diagonal, which just saves itself by turning up at its far end. Thus the mass, and hence usually the special interest of the picture, is on the one side, on the other the vista and the sloping line of the diagonal. In very few cases is the vista behind an attractive or noticeable part of the picture, the fact showing that it acts in opposition to the latter, leading the eye away from it, and thus serving at once the variety and richness of the picture, and its unity. A complete diagonal would have line and vista both working at the extreme outer edge of the picture, and thus too strongly,— unless, indeed, balanced by very striking elements near the outer edge.
This function of the vista as a unifying element is of interest in connection with the theory of Hildebrand,<1> that the landscape should have a narrow foreground and wide background, since that is most in conformity with our experience. He adduces Titian's "Sacred and Profane Love" as an example. But of the general principle it may be said that not the reproduction of nature, but the production of beauty, is the aim of composition, and that this aim is best reached by focusing the eye by a narrow background, i.e. vista. No matter how much it wanders, it returns to that central spot and is held there, keeping hold on all the other elements. Of Hildebrand's example it may be said that the pyramidal composition, with the dark and tall tree in the centre, effectually accomplishes the binding together of the two figures, so that a vista is not needed. A wide background without that tree would leave them rather disjointed.

In general, it may be said that balance in landscape is effected between mass and interest on one side and vista and line on the other; and that union is given especially by the use of vista.
II
The experimental treatment of the isolated elements detected the particular function of each in distributing attention in the field of view. But while all are possibly operative in a given picture, some are given, as we have seen, much more importance than others, and in pictures of different types different elements predominate. In those classes with a general symmetrical framework, such as the altar and Madonna pieces, the elements of interest and direction of attention determine the balance, for they appear as variations in a symmetry which has already, so to speak, disposed of mass and line. They give what action there is, and where they are very strongly operative, they are opposed by salient lines and deep vistas, which act more strongly on the attention than does mass. Interest keeps its predominance throughout the types, except in the portraits, where the head is usually in the central line. But even among the portraits it has a respectable representation, as jewels, embroideries, beautiful hands, etc., count largely too in composition.
The direction of attention is most operative among the portraits. Since these pictures represent no action, it must be given by those elements which move and distribute the attention; in accordance with which principle we find line also unusually influential. As remarked above, altar-pieces and Madonna pictures, also largely without action, depend largely for it on the direction of attention.
The vista, as said above, rivets and confines the attention. We can, therefore, understand how it is that in the genre pictures it appears very numerous. The active character of these pictures naturally requires to be modified, and the vista introduces a powerful balancing element, which is yet quiet; or, it might be said, inasmuch as energy is certainly expended in plunging down the third dimension, the vista introduces an element of action of counterbalancing character. In the landscape it introduces the principal element of variety. It is always to be found in those parts of the picture which are opposed to other powerful elements, and the "heavier" the other side, the deeper the vista. Also in pictures with two groups it serves as a kind of fulcrum, or unifying element, inasmuch as it rivets the attention between the two detached sides.
The direction of suggestion by means of the indication of a line, quite naturally is more frequent in the Madonna picture and portrait classes. Both these types are of large simple outline, so that line would be expected to tell. In a decided majority of cases, combined with vista—the shape being more or less a diagonal slope—it is clear that it acts as a kind of bond between the two sides, carrying the attention without a break from one to the other.
The element of mass requires less comment. It appears in greatest number in those pictures which have little action, i.e. portraits and landscapes, and which are not yet symmetrical,— in which last case mass is, of course, already balanced. In fact, it must of necessity exert a certain influence in every unsymmetrical picture, and so its percentage, even for genre pictures, is large.
