LIGHT AND SHADE
shade," or "shading," creates a feeling as of penetration into space. When a figure is placed in a picture and enveloped in this grading of tones, the illusion is created that it is surrounded by atmosphere. The effect is pictorial.
When light and shade fall. upon an object they model form; when they appear in space they produce depth.
We are indebted to the action of light and shade for the "thickness" of things rendered and for the feel ing of substance. To understand the development of light and shade and the place that they hold in our pic torial language, the period of art immediately embra cing the activity of the Van Eyck brothers should be studied. They introduced oil colors into European art and caused the wonderful development of painting that resulted in the easel picture.
We are not discussing the question whether Japa nese or Chinese art is more desirable than our own, nor are we called upon to decide whether the easel picture is of more or less value than decoration. We have not the power even had we the desire to cast out the effect of traditions inherited from Greek sculpture and Renaissance art, from our literature, philosophy, and religion. The determining factor is always the public need and art must not attempt to overstep our civilization.
