There is little doubt that this is the famous war-idol which stood on the great teocalli of Mexico, and before which so many thousands of human victims were sacrificed. It lay undisturbed underground in the great square, close to the very site of the teocalli, until sixty years ago. For many years after that it was kept buried, lest the sight of one of their old deities might be too exciting for the Indians, who, as I have mentioned before, had certainly not forgotten it, and secretly ornamented it with garlands of flowers while it remained above ground.

The “sacrificial stone,” so called, which also stands in the court-yard of the Museum, was not one of the ordinary altars on which victims were sacrificed. These altars seem to have been raised slabs of hard stone with a protuberant part near one end, so that the breast of the victim was raised into an arch, which made it more easy for the priest to cut across it with his obsidian knife. The Breton altars, where the slab was hollowed into the outline of a human figure, have some analogy to this; but, though there were very many of these altars in different cities of Mexico, none are now known to exist. The stone we are now observing is quite a different thing, a cylindrical block of basalt nine feet across and three feet high: and Humboldt considers it to be the stone described by early Spanish writers, and called temalacatl (spindle-stone) from its circular shape, something like a distaff-head. Upon this the captive chiefs stood in the gladiatorial fights which took place within the space surrounding the great teocalli. Slightly armed, they stood upon this raised platform in the midst of the crowd of spectators; and six champions in succession, armed with better weapons, came up to fight with them. If the captive worsted his assailants in this unequal contest, he was set free with presents; but this success was the lot of but few, and the fate of most was to be overpowered and dragged off ignominiously to be sacrificed like ordinary prisoners. On the top of the stone is sculptured an outline of the sun with its eight rays, and a hollow in the centre, whence a groove runs to the edge of the stone, probably to let the blood run down. All round it is an appropriate bas-relief repeated several times. A vanquished warrior is giving up his stone-sword and his spears to his conqueror, who is tearing the plumed crest from his head.

The above explanation by Humboldt is a plausible one. But in Central America altars not unlike this, and with grooves upon the top, stand in front of the great stone idols; and this curious monument may have been nothing after all but an ordinary altar to sacrifice birds and small animals upon.

THREE VIEWS OF A SACRIFICIAL COLLAR,
Carved out of hard mottled greenstone. (In Mr. Christy’s Collection.)
This is 17 inches long, and varies from 11 to 16 inches in width. The arms are 4 inches wide and 3 inches deep; and are 8 inches apart at about half their length.

Señor Leon Ramirez, the curator, had come to the Museum to meet us, and we went over the collection of smaller objects, which are kept up stairs in glass-cases,—at any rate out of the way of the soldiers.

Here are the stone clamps shaped like the letter U, which were put over the wrists and ankles of the victims, to hold them down on the sacrificial stone. They are of hard stone, very heavy and covered with carvings. It is remarkable that, though the altars for human sacrifices are no longer to be found, these accessory stone clamps, or yoke-like collars, are not uncommon. A fine one from Mr. Christy’s collection is figured. (See opposite page.)

The obsidian knives and arrow-heads are very good, but these I have spoken of already, as well as of the stone hammers. The axes and chisels of stone are so exactly like those found in Europe that it is quite impossible to distinguish them. The bronze hatchet-blades are thin and flat, slightly thickened at the sides to give them strength, and mostly of a very peculiar shape, something like a T, but still more resembling the section of a mushroom cut vertically through the middle of the stalk.

The obsidian mask is an extraordinary piece of work, considering the difficulty of cutting such a material. It was chipped into a rude outline, and finished into its exact shape by polishing down with jeweller’s sand. The polish is perfect, and there is hardly a scratch upon it. At least one of the old Spanish writers on Mexico gives the details of the process of cutting precious stones and polishing them with teoxalli or “god’s sand.” Masks in stone, wood, and terra-cotta are to be seen in considerable number in museums of Mexican antiquities. Their use is explained by passages in the old Mexican writers, who mention that it was customary to mask the idols on the occasion of the king being sick, or of any other public calamity; and that men and women wore masks in some of the religious ceremonies. A fine mask of brown lava (from Mr. Christy’s collection), which has been coloured, is here figured. (See illustration.) The mirrors of obsidian have the same beautifully polished surface as the obsidian mask shows; and those made of nodules of pyrites, cut and polished, are worth notice.
