As the long file of priests and warriors reached the flat summit of the _teocalli_, the Spaniards saw the figures of several men stripped to their waists, some of whom, by the whiteness of their skins, they recognized as their own countrymen. They were the victims for sacrifice. Their heads were gaudily decorated with coronals of plumes, and they carried fans in their hands. They were urged along by blows, and compelled to take part in the dances in honor of the Aztec war-god. The unfortunate captives, then stripped of their sad finery, were stretched, one after another, on the great stone of sacrifice. On its convex surface their breasts were heaved up conveniently for the diabolical purpose of the priestly executioner, who cut asunder the ribs by a strong blow with his sharp razor of _itztli_, and, thrusting his hand into the wound, tore away the heart, which, hot and reeking, was deposited on the golden censer before the idol. The body of the slaughtered victim was then hurled down the steep stairs of the pyramid, which, it may be remembered, were placed at the same angle of the pile, one flight below another; and the mutilated remains were gathered up by the savages beneath, who soon prepared with them the cannibal repast which completed the work of abomination![59] We may imagine with what sensations the stupefied Spaniards must have gazed on this horrid spectacle, so near that they could almost recognize the persons of their unfortunate friends, see the struggles and writhing of their bodies, hear--or fancy that they heard--their screams of agony! yet so far removed that they could render them no assistance. Their limbs trembled beneath them, as they thought what might one day be their own fate; and the bravest among them, who had hitherto gone to battle as careless and light-hearted as to the banquet or the ball-room, were unable, from this time forward, to encounter their ferocious enemy without a sickening feeling, much akin to fear, coming over them.[60] Such was not the effect produced by this spectacle on the Mexican forces, gathered at the end of the causeway. Like vultures maddened by the smell of distant carrion, they set up a piercing cry, and, as they shouted that “such should be the fate of all their enemies,” swept along in one fierce torrent over the dike. But the Spaniards were not to be taken by surprise; and, before the barbarian horde had come within their lines, they opened such a deadly fire from their battery of heavy guns, supported by the musketry and cross-bows, that the assailants were compelled to fall back slowly, but fearfully mangled, to their former position.
