The idea has complete exposition in the vase or baluster in which the commanding lines of the body find both support and extension through the lesser associated parts. These stand as types of complete art revealing the uncompromising principles of domination and subordination.
In the picture, complete in its chiaroscuro, these principles are as easily apprehended as [pg 268] with the more tangible line and space of the solid form. The [“Cow in a Stable,”] by Mauve, contains by his management of this rude and simple subject all the possibilities opened to and demanded by compositions involving many elements. It might stand as the light and dark scheme for some of the allegories of Rubens, Wiertz or Correggio, or for many genre interiors, or for an “arrangement” of flowers.
When once the importance of this principle is realized many of the pitfalls into which beginners are so prone to fall are covered, and that forever. Time and regrets are both saved to the student who will pause for the absorption of the few principles on which all the arts are founded.
This idea may seem to disturb the notion of balance across the centre, especially when the object which receives our first consideration occupies one side of the picture. A study of the postulates together with the principle of the steelyard and the knowledge of picture balance will clear any apprehension of conflict.
The Dominant Idea
Above and beyond the object which dominates all others is the idea which dominates the picture. Such may be light, gloom, space, action, passion, repose, communion, humor, or whatever has stimulated and therefore must govern the composition. If with the sentiment of Repose as subjective, the principal object expresses action, there must necessarily be conflict between the idea and the reality.
Action, however, may very appropriately be [pg 269] introduced into a conception of repose, its contrast heightening this emotion; the creeping baby, the frolicking kitten, the swinging pendulum, the distant toilers observed by a nearer group at rest.
The point where a counter emotion weakens and where it strengthens the idea is determined on a scale of degree, many necessary parts taking precedence thereto before the opposed sentiment shall attract us. These ideas, correlative to their principal, have also their scale of attraction, and only in the formal arrangement of allegory and decoration may two units be allowed the same degree of attraction. This is one of the most frequent forms in which weak composition develops, leaving the mind uncertain as to the sequence, and the eye wavering between the equal claims of separated parts. The neglect of leading lines, or of forcing a logical procedure from part to part, so that no part may escape the continuous inspection of all, produces decomposition. The avoidance of inharmony must of course yield harmony.
