As regards the use of dolls it would be interesting to know whether the child would of its own accord so treat any beloved object if it had never seen a real doll made by adults, but the artificial doll is always provided so early that there is no opportunity to make the experiment. In the slums of a great city a proper subject might perhaps be found. However, we know that the child’s powers of illusion are amazing. A cushion, a stick, a building block, an umbrella, a dust brush, or a footstool, a table cover, a slipper, a fork, in short, anything portable, is liable to become a beloved and zealously nurtured baby, and every detail is quickly arranged to suit the picture.[579] Finally, a few words as to the origin of this toy. Its use is well-nigh universal, and one of the sights most worth seeing in an ethnological museum is a collection of dolls from all over the world. They are made of clay, of edible earth, of wax, of wood, of bark, of cloth, of porcelain, etc., and imitations of the human figure blend with those of animals, of household furniture and utensils, of arms and implements of different sorts in motley variety.[580] They serve to illustrate human progress. In mediæval Europe, in ancient Rome, in Greece—everywhere the doll was at home. The old museum in Berlin, for example, possesses a wooden doll from the Egyptian excavations, which has movable legs, and a crocodile whose jaws can open and shut. Since these images of men and animals were probably the earliest form of toys, the conclusion is natural that they probably originated with idols which from religious feeling may have lain in the cradles and thus appealed to the children as playthings. Other customs and the testimony of travellers give colour to this idea, though it is difficult to draw the line between the idol and the doll.[581] Through the kindness of my former colleague, Sticker, at Giessen, I myself own an old Indian wooden doll, which appears suited to be both a protection from evil spirits and a toy for children. Still, we must not allow to pass unchallenged any manifestation of the disposition which used to be so common, to refer everything to a religious origin. It is quite possible that simple pleasure in plastic representation for its own sake is responsible for the manufacture of these toys. Von den Steinen tells us, “Dolls a span long, made of straw, served as children’s toys, and were also stuck in a pole on the roof of their places of festivity as a sign that some frolic was in progress, and everybody spread the news.”[582] There is nothing here to hint at a religious significance.
