The art of representation at first possessed little artistic beauty, though the decorations on walls of caves show skill in lines and color. The first representations sought only intelligence in communicating thought. The bas-reliefs of the ancients showed skill in representation. The ideal was finally developed until the aesthetic taste was improved, and the Greek sculpture shows a high development of artistic taste. In it beauty and truth were harmoniously combined. The arts of sculpture and painting are based upon the imagination. Through its perfect development, and the improvement in the art of execution, have been secured the aesthetic products of man. Yet there is always a mingling of the emotional nature {136} in the development of fine arts. The growth of the fine arts consists in intensifying the pleasurable sensations of eye and ear. This is done by enlarging the capacity for pleasure and increasing the opportunity for its satisfaction. The beginnings of the fine arts were small, and the capacity to enjoy must have been slowly developed. Of the arts that appeal to the eye there may be enumerated sculpture, painting, drawing, landscape-gardening, and architecture. The pleasure from all except the last comes from an attempt to represent nature. Architecture is founded upon the useful, and combines the industrial and the fine arts in one. The attempt to imitate nature is to satisfy the emotions aroused in its contemplation. _The Love of the Beautiful Slowly Develops_.--There must have developed in man the desire to make a more perfect arrow-head, axe, or celt for the efficiency of service, and later for beauty of expression. There must early have developed an idea of good form and bright colors in clothing. So, too, in the mixing of colors for the purpose of expressing the emotions there gradually came about a refinement in blending. Nor could man's attention be called constantly to the beautiful plants and flowers, to the bright-colored stones, metals, and gems found in the earth without developing something more than mere curiosity concerning them. He must early have discovered the difference between objects which aroused desire for possession and those that did not. Ultimately he preferred a more beautifully finished stone implement than one crudely constructed--a more beautiful and showy flower than one that was imperfect, and likewise more beautiful human beings than those that were crude and ugly.
