It was quite literally his hand, indeed, that he tried at first; for the earliest decoration upon paleolithic pottery is made by pressing the fingers into the clay so as to produce a couple of deep parallel furrows, which is the sole attempt at ornament on M. Joly's Nabrigas specimen; while the urns and drinking-cups taken from our English long barrows are adorned with really pretty and effective patterns, produced by pressing the tip of the finger and the nail into the plastic material. It is wonderful what capital and varied results you can get with no more recondite graver than the human finger-nail, sometimes turned front downward, sometimes back downward, and sometimes used to egg up the moist clay into small jagged and relieved designs. Most of these patterns are more or less plaitlike in arrangement, evidently suggested to the mind of the potter by the primitive marks of the old basketwork. But, as time went on, the early artist learned to press into his service new implements, pieces of wood, bone scrapers, and the flint knife itself, with which he incised more regular patterns, straight or zigzag lines, rows of dots, squares and triangles, concentric circles, and even the mystic cross and swastika, the sacred symbols of yet unborn and undreamt-of religions. As yet, there was no direct imitation of plant or animal forms; once only, on a single specimen from a Swiss lake dwelling, are the stem and veins of a leaf dimly figured on the handiwork of the European prehistoric potter. Ornament in its pure form, as pattern merely, had begun to exist; imitative work as such was yet unknown, or almost unknown, to the eastern hemisphere. In America, it was quite otherwise. The forgotten people who built the mounds of Ohio and the great tumuli of the Mississippi valley decorated their pottery not only with animal figures, such as snakes, fish, frogs, and turtles, but also with human heads and faces, many of them evidently modelled from the life, and some of them quite unmistakably genuine portraits. On one such vase, found in Arkansas, and figured by the Marquis de Nadaillac in his excellent work on Prehistoric America, the ornamentation consists (in true Red Indian taste) of skeleton hands, interspersed with crossbones; and the delicacy and anatomical correctness of the detail inevitably suggest the idea that the unknown artist must have worked with the actual hand of his slaughtered enemy lying for a model on the table before him. Much of the early American pottery is also coloured as well as figured, and that with considerable real taste; the pigments were applied, however, after the baking, and so possess little stability or permanence of character. But pots and vases of these advanced styles have got so far ahead of the first potter that we have really little or no business with them in this paper.
