The following examples depart still further from nature, approaching the border line between the distinctly imitative and the purely conventional or geometric phases. In the first (Fig. 263) all the leading features are recognizable, but are very much simplified. The
jaws are without teeth, the head is without eyes, and the body without indication of scales. The other example (Fig. 264) is of a somewhat different type and may possibly refer to some other reptilian form, but many links connecting the two are found. The shape is more angular and is a step further removed from nature. From shapes as conventional as this we drop readily into purely geometric forms, as will be seen further on. These and the preceding drawings are all executed on broad surfaces, where fancy could have free play. The modifying or conventionalizing forces are, therefore, quite vague. Variation from natural forms is due partly to a lack of skill on the part of the painter, partly to the peculiar demands of ceramic embellishment, and partly to the traditional style of treatment acquired in still more primitive stages of culture and in other and unidentified branches of art.

I shall now call attention to some important individualized or well defined agencies of convention. First, and most potent, may be mentioned the enforced limits of the spaces to be decorated, which spaces take shape independently of the subject to be inserted. When the figures must occupy a narrow zone they are elongated, when they must occupy a square they are restricted longitudinally, and when they must occupy a circle they are of necessity coiled up. Fig. 265
illustrates the effect produced by crowding the oblong figure into a short rectangular space. The head is turned back over the body and the tail is thrown down along the side of the space. In Fig. 266 the figure occupies a circle, and is in consequence closely coiled up, giving the effect of a serpent rather than an alligator. In Fig. 267 the space is semicircular, and we observe peculiar conventional conditions, some of which may be due to other causes. For example, such spaces may originally have been filled with purely geometric figures, which tended to impart their own characters to the life forms that supplanted them.
