The first thing that strikes one on looking at them is that, despite differences in detail, the design presents a general common character. In fact, there is question not of figures with undecided forms, but with sure lines perfectly traced and combined in one and the same style. They are geometric designs rather than objective representations. The illustration [Fig. 108] came from a rock in the vicinity of Caïcara, a town situated on the right bank of the Orinoco, close to its last great bend. It represents three jaguars, one large and two small, the former being separated from the latter by an ornamented sun placed at the level of their feet. The spotting of their hides is rendered by means of angular lines arranged in so regular a manner that one might take them to be tigers did he not know that these felines never existed in these regions. The jaguars differ in insignificant details which, however, must have a purpose, in view of the general regularity. The largest shows six radiating lines on the muzzle and a circle in one of the ears. The second shows two hooks on the lower part of the body. The third is preceded by an isolated head, which is unfinished, without ears, inclined differently from the others. Some differences are also noted in the limbs. Placed in the attitude of marching, these animals seem to descend from a height and to follow the same direction. Perhaps there is question here of a mnemonic whole, and, we might add, of a totem, if we knew that that system had been employed by the Indians of the region. The same author (p. 205) gives a description of the petroglyphs of the rapids of Chicagua, here presented as Fig. 109. [Illustration: FIG. 109.--Petroglyphs of Chicagua rapids, Venezuela.] This interesting collection includes the most varied ideographs. Alongside of representations analogous to the preceding there appear new characters and partial groupings which we had not yet found. On running over them one passes successively from simple points to figures made up of tangled lines, to objective representations, and even to letters of the alphabet, a resemblance which, of course, is fortuitous.
