The teocalli which Fernando Cortes and his companions saw at Mexico, and which the conqueror razed to the ground, to replace it by a Catholic church, was not of any great antiquity. It had been constructed thirty-four years before, in the place of another much smaller one that dated from the time when the Aztecs were but an insignificant tribe; and it seems that frightful human hecatombs had ensanguined the foundations of this more recent teocalli. Some authorities speak of seventy-two or eighty thousand victims, while more moderate calculations reduce the number to twenty thousand, which is surely terrible enough. In front of the temple there stretched a spacious court some twelve hundred feet square. All around were smaller buildings, which served as habitations for the priests, and store-houses for the apparatus of worship, as well as arsenals, oratories for the sovereign and the grandees of the empire, chapels for the inferior deities and so on. Amongst these buildings was the temple in which, as I have said, the gods of the conquered peoples were literally imprisoned. In another the Spaniards could count a hundred and thirty-six thousand symmetrically-piled skulls. They were the skulls of all the victims that had been sacrificed since the foundation of the sanctuary. And, by a contrast no less than monstrous, side by side with this monument of the most atrocious barbarism there were halls devoted to the care of the poor and sick, who were tended gratuitously by priests.[7] What a tissue of contradictions is man! But the Aztec religion does not allow us to dwell upon the note of tenderness. In the centre of the broad platform at the summit stood the _stone of sacrifices_, a monolith about three feet high, slightly ridged on the surface. Upon this stone the victim was stretched supine, and while sundry subordinate priests held his head, arms and feet, the sacrificing pontiff raised a heavy knife, laid open his bosom with one terrific blow, and tore out his heart to offer it all bleeding and palpitating to the deity in whose honour the sacrifice was performed. And here you will recognize that idea, so widely spread in the two Americas, and indeed almost everywhere amongst uncivilized peoples, that the heart is the epitome, so to speak, of the individual--his soul in some sense--so that to appropriate his heart is to appropriate his whole being.
