In the Introduction I referred to what were termed certain needs which constrained man to artistic effort. These were art, information, wealth, and religion, and they will now be treated as briefly as may be, since it is impossible to deal adequately with them.

I. Art.

Æsthetics is the study and practice of art for art’s sake, that is, for the pleasurable sensations which are induced by certain combinations of form, line, and colour. It does not signify for our purpose how the feeling for art has been obtained, nor is an analysis of the sensations necessary. All men have this sense, varying from a rudimentary to an exalted extent. Though it is naturally the basis of all art work, it does not follow that the æsthetic sense has been the sole cause of decorative work. Religion and the desire to convey information have both imitated and controlled pictorial and decorative art, but the artistic sense has all along exerted its influence to a greater or less extent. The artistic feeling has endeavoured to cast a glamour of beauty over the crude efforts of religion and science.

In the scheme of the life-history of pictorial or decorative designs given on p. [8], I have considered only those which have originated from various combinations of originally solitary figures. Separate portraits whether of men or animals, either in the flat or in the round, have been omitted as they remain in the lowest place of development, though they may attain to the highest excellence of art. Those who have followed the brilliant researches in classical archæology will appreciate what I mean by the life-history of representations. The origin, rise, glorious consummation, and decadence of Greek statuary is a striking illustration of my theme.

Figures may be grouped not only to convey a sentiment, as in a picture, but merely for decorative effect. The artist in this case usually at once adopted a conventional treatment. In some instances strict realism may be appropriate, but in the greater number of conditions it is most inappropriate.

Walls, fabrics, and platters have from time immemorial been decorated in this manner. Many books have been written illustrating this branch of art and laying down principles of design, and the reader is referred to these, as this subject does not fall within the scope of the present essay.

I would like to point out in this place that there is a very instructive field for study in the consideration of the decorative methods of various peoples. The way in which areas are decorated, the idea of symmetry, and such-like subjects; for example, the essence of Japanese decorative art is asymmetry, and the results are charming to our eyes although we have been reared amongst symmetrical designing. Symmetry may be exhibited in the equal balancing of dissimilar designs, as is commonly done by Oriental artists, or in the mechanical duplication in relation to a median line which is so dear to European decorators.

The style of the decorative art of a savage or barbaric people is a legacy and its perpetuation is usually binding, not merely by custom but more frequently by religion. When all the various factors are taken into account, one finds that the æsthetic sense of a savage artist is not so very different after all from that of his civilised fellow-craftsman, and one can see in the disposition or the introduction of certain elements in a design, that both are actuated by the same æsthetic sense of what is suitable,—both are, in fact, artists.

In the section on Physicomorphs I allude to the rarity of landscape drawing among savage peoples, and give an illustration (Fig. [66]) of one, from Torres Straits, which occurred casually on a bamboo pipe; there is another but poorer landscape from the same locality in the Oxford University Museum. Early attempts, such as these, at pictures are especially interesting as illustrating the working of the mind of the artists.

It is not within the scope of this book to trace the history either of pictorial art or of individual pictures. The genesis of a great picture is most interesting, and it may occasionally be traced owing to the fortunate preservation of the artist’s sketches and studies. It often happens that some of the figures in the finished picture have lost the vitality which they had in the sketch stage, even such a great artist as Raffael could not always reproduce the spirit of his own work.
