TRANSCRIBER'S NOTES

In the original of this work, most pages are headed by a topic phrase, so that a topic can be located quickly by riffling the pages of the book. In this etext, the same topic phrases appear in right-aligned boxes near the text that begins that topic. Thus a topic can be found by scrolling the text and scanning the right margin.

The many images of the original are inline here as grayscale graphics in PNG format, scaled to 480 or 512 pixels width. When an image has a pale-gray border, the reader can click on the image to open a higher-resolution version.

In the original, the requirements of book design often caused the editors to place images some distance from the text that discussed them. In this etext some images are placed closer to the point where they are mentioned and thus not at their original page number. Each image has a number, for example f016. In the List of Illustrations and the Index, references to images by page number have been replaced by these figure numbers, which are linked to the images. Within the body text, references to a figure by its page number are linked to the image, not the specified page.

Two minor typos were corrected: thing to think on page 10 and intregal to integral on page 197.

OF LINE AND FORM

CHAPTER I

Silhouette

As children we probably perceive forms in nature defined as flat shapes of colour relieved upon other colours, or flat fields of light on dark, as a white horse is defined upon the green grass of a field, or a black figure upon a background of snow.

To define the boundaries of such forms becomes the main object in early attempts at artistic expression. The attention is caught by the edges—the shape of the silhouette which remains the paramount means of distinction of form when details and secondary characteristics are lost; as the outlines of mountains remain, or are even more clearly seen, when distance subdues the details of their structure, and evening mists throw them into flat planes one behind the other, and leave nothing but the delicate lines of their edges to tell their character. We feel the beauty and simplicity of such effects in nature. We feel that the mind, through the eye resting upon these quiet planes and delicate lines, receives a sense of repose and poetic suggestion which is lost in the bright noontide, with all its wealth of glittering detail, sharp cut in light and shade. There is no doubt that this typical power of outline and the value of simplicity of mass were perceived by the ancients, notably the Ancient Egyptians and the Greeks, who both, in their own ways, in their art show a wonderful power of characterization by means of line and mass, and a delicate sense of the ornamental value and quality of line.
