The Common Sacrifice, offered in the Aztec temples was performed by a chief priest, and six assistants. The principal flamen, habited in a red scapulary fringed with cotton, and crowned with a circlet of green and yellow plumes, assumed, for the occasion, the name of the deity to whom the offering was made. His acolytes,—clad in white robes embroidered with black; their hands covered with leathern thongs; their foreheads filleted with parti-colored papers; and their bodies dyed perfectly black,—prepared the victim for the altar, and having dressed him in the insignia of the deity to whom he was to be sacrificed, bore him through the town begging alms for the temple. He was then carried to the summit of the Teocalli, where four priests extended him across the curving surface of an arched stone placed on the sacrificial stone, while another held his head firmly beneath the yoke which is represented elsewhere. The chief priest,—the topiltzin or sacrificer, then stretched the breast of the victim tightly by bending his body back as far as possible, and, seizing the obsidian knife of sacrifice, cut a deep gash across the region of the captive's heart. The extreme tension of the flesh and muscles, at once yielded beneath the blade, and the heart of the victim lay palpitating in the bloody gap. The sacrificer immediately thrust his hand into the wound, and, tearing out the quivering vital, threw it at the feet of the idol,—inserted it with a golden spoon into its mouth,—or, after offering it to the deity, consumed it in fire and preserved the sacred ashes with the greatest reverence. When these horrid rites were finished in the temple, the victim's body was thrown from the top of the Teocalli, whence it was borne to the dwelling of the individual who offered the sacrifice, where it was eaten by himself and his friends, or, was devoted to feed the beasts in the royal menagerie.
Numerous cruel sacrifices were practised by the Indians of Mexico, and especially among the Quauhtitlans, who, every four years, slew eight slaves or captives, in a manner almost too brutal for description. Sometimes the Aztecs contented themselves with other and more significant oblations; and flowers, fruits, bread, meat, copal, gums, quails, and rabbits, were offered on the altars of their gods. The priests, no doubt, approved these gifts far more than the tough flesh of captives or slaves!
The Gladiatorial Sacrifice was reserved, as we have already said for noble and courageous captives. According to Clavigero, a circular mass, three feet high, resembling a mill stone, was placed within the area of the great temple upon a raised terrace
