Among these abundant remains of culture archæologists were surprised to find real objects of art from the hand of Drift Man, proving that thinking about his surroundings had developed into the ability to reproduce what he saw in drawing and modelling. The first objects of this kind were found in the caves of the Périgord. They are, on the one hand, drawings scratched on stones, reindeer bones, or pieces of horn, mostly very naïve, but sometimes really lifelike, chiefly representing animals, but also men; on the other hand imitations plastically carved out of pieces of reindeer horn, bones, or teeth. Such engravings also occurred on pieces of ivory, and plastic representations in this material have been preserved. On a cylindrical piece of reindeer horn from the cave excavations in the Dordogne is the representation of a fish, and on the shovel-piece of a reindeer’s horn are the head and breast of an animal resembling the ibex. Illustrations of horses give faithful reproductions of the flowing mane, unkempt tail, and disproportionately large head of the large-headed wild horse of the Drift. The most important among these representations are such as endeavour to reproduce an historical event. An illustration of this kind represents a group consisting of two horses’ heads and an apparently naked male figure; the latter bears a long staff or spear in his right hand, and stands beside a tree, which is bent down almost in coils in order to accommodate itself to the limited space, and whose boughs, indicated by parallel lines, show it to be a pine or fir. Connected with the tree is a system of vertical and horizontal lines, apparently representing a kind of hurdlework. On the other side of the same cylindrical piece are two bisons’ heads. Doubtless this picture tells a tale; it is picture-writing in exactly the same sense as that of the North American Indians. Our picture already shows the transition to abbreviated picture-writing, as, instead of the whole animals--horses and bisons--only the heads are given. The message-sticks of the Australians bear certain resemblances; Bastian has rightly described them as the beginnings of writing. If we have interpreted them aright, the finds that have been made, with the tally from the source of the Schussen and the message-stick from the caves of the Dordogne, place the art of counting, the beginnings of writing, the first artistic impulses, and other elements of primitive culture right back in the Drift period.
