In casting the eye over a Mexican manuscript, or map, as it is called, one is struck with the grotesque caricatures it exhibits of the human figure; monstrous, overgrown heads, on puny, misshapen bodies, which are themselves hard and angular in their outlines, and without the least skill in composition. On closer inspection, however, it is obvious that it is not so much a rude attempt to delineate nature, as a conventional symbol, to express the idea in the most clear and forcible manner; in the same way as the pieces of similar value on a chess-board, while they correspond with one another in form, bear little resemblance, usually, to the objects they represent. Those parts of the figure are most distinctly traced which are the most important. So, also, the coloring, instead of the delicate gradations of nature, exhibits only gaudy and violent contrasts, such as may produce the most vivid impression. “For even colors,” as Gama observes, “speak in the Aztec hieroglyphics.”[146] But in the execution of all this the Mexicans were much inferior to the Egyptians. The drawings of the latter, indeed, are exceedingly defective, when criticised by the rules of art; for they were as ignorant of perspective as the Chinese, and only exhibited the head in profile, with the eye in the centre, and with total absence of expression. But they handled the pencil more gracefully than the Aztecs, were more true to the natural forms of objects, and, above all, showed great superiority in abridging the original figure by giving only the outline, or some characteristic or essential feature. This simplified the process, and facilitated the communication of thought. An Egyptian text has almost the appearance of alphabetical writing in its regular lines of minute figures. A Mexican text looks usually like a collection of pictures, each one forming the subject of a separate study. This is particularly the case with the delineations of mythology; in which the story is told by a conglomeration of symbols, that may remind one more of the mysterious anaglyphs sculptured on the temples of the Egyptians, than of their written records.
