We may note here for reference the signification of one of the hieroglyphs in the right-hand half of Fig. 52, _i. e._, in that half which contains only writing. The topmost _chiffre_ is undoubtedly the name, or part of the name, of the principal figure represented in the other half. It is in pure picture-writing; that is, it expresses the sum of his attributes. It has the crotalus mask, with nose ornament, which he wears over his face; then the cross, with the "five feathers" of Mexico, and the sun symbol. These are in the middle of the _chiffre_. Below these the oval may be, and probably is, heaven, with the rain descending and producing from the surface of the earth (the long axis of the ellipse), the seed, of which three grains are depicted. We know by the occurrence of the hieroglyphs on the reverse side of the stone that this is not of Aztec sculpture. These symbols are of the same sort as those at Copan, Palenque, etc., and I shall show later that some of them occur in the Palenque tablets. Hence, we know this engraving to be Yucatec and not Aztec in its origin. If it had been sculptured on one side only, and these hieroglyphs omitted, I am satisfied that the facts which I shall point out in the next paragraphs would have led to the conclusion that this stone was Mexican in its origin. Fortunately the native artist had the time to sculpture the Yucatec hieroglyphs, which are the proof of its true origin. It was not dropped by a traveling Aztec; it was made by a Yucatec. In passing, it may be said that the upper left-hand, hieroglyph of Plate XIII most probably repeats this name. I collect from the third volume of BANCROFT'S _Native Races_, chapter viii, such descriptions of HUITZILOPOCHTLI as he was represented among the Mexicans as will be of use to us in our comparisons. No display of learning in giving the references to the original works is necessary here, since Mr. BANCROFT has placed all these in order and culled them for a use like the present. It will suffice once for all to refer the critical reader to this volume, and to express the highest sense of obligation to Mr. BANCROFT'S compilation, which renders a survey of the characteristic features of the American divinities easy. In Mexico, then, this god had, among other symbols, "five balls of feathers arranged in the form of a cross." This was in reference to the mysterious conception of his mother through the _powers of the air_. The upper hieroglyph in Fig. 52, and one of the lower ones, contain this sign: "In his right hand he had an azured staff cutte in fashion of a waving snake." (See Plate LXI of STEPHENS.) "Joining to the temple of this idol there was a piece of less work, where there was another idol they called TLALOC. These two idolls were alwayes together, for that they held them as companions and of equal power."
