In this observation we have a key that will unlock many of the mysteries of form.
In the investigation of this point it will be necessary to consider the processes by which an art inherits or acquires the forms of another art or of nature, and how one material imposes its peculiarities upon another material. In early stages of culture the processes of art are closely akin to those of nature, the human agent hardly ranking as more than
a part of the environment. The primitive artist does not proceed by methods identical with our own. He does not deliberately and freely examine all departments of nature or art and select for models those things most convenient or most agreeable to fancy; neither does he experiment with the view of inventing new forms. What he attempts depends almost absolutely upon what happens to be suggested by preceding forms, and so narrow and so direct are the processes of his mind that, knowing his resources, we could closely predict his results.
The range of models in the ceramic art is at first very limited, and includes only those utensils devoted to the particular use to which the clay vessels are to be applied; later, closely-associated objects and utensils are copied. In the first stages of art, when the savage makes a weapon, he modifies or copies a weapon; when he makes a vessel, he modifies or copies a vessel.
This law holds good in an inverse ratio to culture, varying to a certain extent with the character of the material used.
Natural originals.—Natural originals, both animal and vegetable, necessarily differ with the country and the climate, thus giving rise to individual characters in art forms often extremely persistent and surviving decided changes of environment.
The gourd is probably the most varied and suggestive natural vessel. We find that the primitive potter has often copied it in the most literal manner. One example only, out of the many available ones, is necessary. This is from a mound in southeastern Missouri.
In Fig. 464, a illustrates a common form of the gourd, while b represents the imitation in clay.
