In beginning the study of Chiriquian decorative art I found it impossible to approach the subject advantageously from the geometric side, as was done in the Pueblo study, since life elements so thoroughly permeate every part of it. I have, therefore, turned about, and in the following study present first the more realistic delineations of nature, arranging long series of derivative shapes which descend through increasing degrees of convention to purely geometric forms. These remarks relate wholly to the plan or linear arrangement of the motives. As to method of realization, ceramic ornament may be arranged in two classes: the plastic or relieved and the non-plastic or flat. Life forms are freely rendered by both plastic and non-plastic methods, and in either style may range from the highly realistic to the purely geometric. As shown in a preceding section, plastic life forms in Chiriquian art appear to have been subject to two divergent lines of thought, the one trivial and the other serious. Through the one we have grotesque and perhaps even humorous representations of men and of animals. The figures are attached to the vessels for the purpose--perhaps for the exclusive purpose--of embellishment, and often with excellent success, as judged by our own standards of taste. The other deals with plastic representations apparently of a serious nature, although utilized also for embellishment. The animal forms employed are treated in a way to suggest that in the mind of the artist the creature bore a definite relation to the vessel or its use, a relationship originating in superstition and preserved throughout all changes of form. Their office was symbolic, and this office was probably not always lost sight of by the potter, even though, through the forces of convention, the animal shapes were reduced to mere knobs, ridges, or even to painted devices. In color delineations, although the same subjects are to a great extent employed, there is necessarily greater constraint--there is less freedom as well as less vigor in the presentation of natural forms. There is apparently no attempt at the grotesque or amusing. The variants are practically infinite. The work is more purely decorative and is perhaps less subject to the restraints of associated ideas and of use with particular vessels or in definite relations to other features of the vessel. At the same time it is manifest that these painted figures are not all merely meaningless decorations, but that many, throughout all degrees of modification, refer with greater or less clearness to natural originals, to ideas associated with these originals, or to the relationship of these originals to the vessel and its uses.
