Jacque has been successful in the management of what is considered a difficult form. In the herder with cattle although we feel in the next moment the subject will have passed, while it lasts the artist has kept the eye upon it by the use of dark figures at either end and a concentration of light in the centre; also by the presence of the tree in the distance which turns the eye into the picture as it leaves the cow on the right.
Another example more complete as a composition is his famous _“__Shepherd and Sheep,__”_(11) in which the angle is formed by the dark dog at the extreme right, the lines expanding through the figure of the shepherd and thence above into a group of trees and below along the edge of the flock. In this example the base line runs into the picture by perspective and thence back into the picture to the trees.
The _“__Departure for the Chase,__”_ by Cuyp, shows an unsuccessful use of this shape.
In _“__The Path of the Surf,__”_ the main form—the surf—is a triangle and the two supporting spaces triangles. Such a construction is particularly stable, as these focalize on the line of interest. Some artists construct most of their pictures in a series of related triangles. The writer calling upon Henry Bacon found him painting a group of transatlantic travellers on a steamer’s deck. He pointed out a scheme of triangles which together formed one great triangle, but said he was looking for the last point for the base of this. A monthly magazine was suggested, which, laid open on its face, proved _le dernier clou._
When Giotto was asked for his conception of a perfect building, he produced a circle. When Michael Angelo was appealed to, he designated the cross. On both bases may good architecture and good pictures be founded. If the extremities of the Greek cross be connected by arcs, a circle will result, and if the Latin cross be so bounded we will have a kite-shape, or ellipse. The two designs are, therefore, not as dissimilar as may at first be supposed. In both, from the pictorial standpoint, they are the framework by means of which the same given space may be filled.
The simple vertical line is monotonous. Its bisection produces balance; a cross is the result. Again, two crosses placed together, the arms touching, and three crosses in like position, will represent the picture plan of the grouping so frequently used by Raphael—a central figure balanced by one on either side, the horizon joining them, and behind this the balance repeated in trees and other figures.
