Venice Academy. All the mass and the interest and the suggestion of the downward lines and of the magnificent perspective toward the left, and the effect of the whole space composition is of superb largeness of life and feeling. Compare Titian's "Presentation of the Virgin," also the two great compositions by Veronese, "Martyrdom of St. Mark," etc., in the Doge's Palace, Venice, and "Esther before Ahaseurus," in the Uffizi, Florence. In these last two, the mass, direction of interest, movement, and attention are toward the left, while all the lines tend diagonally to the right, where a vista is also suggested,--the diagonal making a V just at the end. Here, too, the effect is of magnificence and vigor. If, then, the pyramid belongs to contemplation, the diagonal to action, what ca be said of landscape? It is without action, it is true, and yet does not express that positive quality, that WILL not to act, of the rapt contemplation. The landscape uncomposed is negative, and it demands unity. Its type of composition, then, must give it something positive besides unity. It lacks both concentration and action; but it can gain them both from a space composition which shall combine unity with a tendency to movement. And this is given by the diagonal and V-shaped type. This type merely allows free play to the natural tendency of the "active" picture; but it constrains the neutral, inanimate landscape. The shape itself imparts motion to the picture: the sweep of line, the concentration of the vista, the unifying power of the inverted triangle between two masses, act, as it were, externally to the suggestion of the object itself. There is always enough quiet in a landscape,-- the overwhelming suggestion of the horizontal suffices for that; it is movement that is needed for richness of effect, and, as I have shown, no type imparts the feeling of movement so strongly as the diagonal and V-shaped type of composition. Landscapes need energy to produce "stimulation," not repression, and so the diagonal type is proportionately more numerous.
