[12] The unique Knife figured at [page 101] and two masks incrusted with a similar mosaic work (of turquoise and obsidian) are in Mr. Christy’s collection; and a mask and head of similar workmanship are in the collection at Copenhagen. These are the only known examples of this advanced style of Aztec art.
The whole once belonged probably to one set, brought to Europe soon after the Conquest of Mexico. The two at Copenhagen were obtained at a convent in Rome; and, of the other three, two were for a long period in a collection at Florence, and the other was obtained at Bruges, where it was most probably brought by the Spaniards during their rule in the Low Countries.

The wonderful similarity of character among the stone weapons found in different parts of the world has often been used by ethnologists as a means of supporting the theory that this and other arts were carried over the world by tribes migrating from one common centre of creation of the human species. The argument has not much weight, and a larger view of the subject quite supersedes it.

We may put the question in this way. In Asia and in Europe the use of stone tools and weapons has always characterized a very low state of civilization; and such implements are only found among savage tribes living by the chase, or just beginning to cultivate the ground and to emerge from the condition of mere barbarians. Now, if the Mexicans got their civilization from Europe, it must have been from some people unacquainted with the use of iron, if not of bronze. Iron abounds in Mexico, not only in the state of ore, but occurring nearly pure in aerolites of great size, as at Cholula, and at Zacatecas, not far from the great ruins there; so that the only reason for their not using it must have been ignorance of its qualities.

The Arabian Nights’ story of the mountain which consisted of a single loadstone finds its literal fulfilment in Mexico. Not far from Huetamo, on the road towards the Pacific, there is a conical hill composed entirely of magnetic iron-ore. The blacksmiths in the neighbourhood, with no other apparatus than their common forges, make it directly into wrought iron, which they use for all ordinary purposes.

Now, in supposing civilization to be transmitted from one country to another, we must measure it by the height of its lowest point, as we measure the strength of a chain by the strength of the weakest link. The only civilization that the Mexicans can have received from the Old World must have been from some people whose cutting implements were of sharp stone, consequently, as we must conclude by analogy, some very barbarous and ignorant tribe.

From this point we must admit that the inhabitants of Mexico raised themselves, independently, to the extraordinary degree of culture which distinguished them when Europeans first became aware of their existence. The curious distribution of their knowledge shows plainly that they found it for themselves, and did not receive it by transmission. We find a wonderful acquaintance with astronomy, even to such details as the real cause of eclipses,—and the length of the year given by intercalations of surprising accuracy; and, at the same time, no knowledge whatever of the art of writing alphabetically, for their hieroglyphics are nothing but suggestive pictures. They had carried the art of gardening to a high degree of perfection; but, though there were two kinds of ox, and the buffalo at no great distance from them, in the countries they had already passed through in their migration from the north, they had no idea of the employment of beasts of burden, nor of the use of milk. They were a great trading people, and had money of several kinds in general use, but the art of weighing was utterly unknown to them; while, on the other hand, the Peruvians habitually used scales and weights, but had no idea of the use of money.

To return to the stone knives; the Mexicans may very well have invented the art themselves, as they did so many others; or they may have received it from the Old World. The things themselves prove nothing either way.

The real proof of their having, at some early period, communicated with inhabitants of Europe or Asia rests upon the traditions current among them, which are recorded by the early historians, and confirmed by the Aztec picture-writings; and upon several extraordinary coincidences in the signs used by them in reckoning astronomical cycles. Further on I shall allude to these traditions.

On the whole, the most probable view of the origin of the Mexican tribes seems to be the one ordinarily held, that they really came from the Old World, bringing with them several legends, evidently the same as the histories recorded in the book of Genesis. This must have been, however, at a time, when they were quite a barbarous, nomadic tribe; and we must regard their civilization as of independent and far later growth.

We rode back through the woods to Guajalote, where the Mexican cook had made us a feast after the manner of the country, and from her experience of foreigners had learnt to temper the chile to our susceptible throats. Decidedly the Mexicans are not without ideas in the matter of cookery. We stayed talking with the hospitable Don Alejandro and his sister till it was all but dark, and then rode back to the Real, admiring the fire-flies that were darting about by thousands, and listening to our companion’s stories, which turned on robberies and murders—-as stories are apt to do in wild places after dark. But, save an escape from being robbed some twenty years back, and the history of an Indian who was murdered just here by some of his own people, for a few shillings he was taking home, our friend had not much reason to give for the two huge horse-pistols he carried, ready for action. His story of the death of a German engineer in these parts is worth recording here. He was riding home one dark night, with a companion; and, trusting to his knowledge of the country, tried a short cut through the woods, among the old open mines near the Regla road. They had quite passed all the dangerous places, he thought, so he gave his horse the spur, and plunged sheer down a shaft, hundreds of feet deep. His friend pulled up in time, and got home safely.
