Foremost among sacrificial donations was the human heart (tona), seat of the teyolia that moderns call the soul. It was believed to be a fragment of the sun’s fire (istli), the invisible seed of life that never dies. The instrument of sacrifice, the nahui tecpatl, was a knife divinized as a god, the implement of the Fifth Sun, used for heart extraction. It was a short six-to-eight-inch-long flint or obsidian double-edge blade with, for important ceremonies, a mosaic crouched figure of a god on the handle. The carved image shows circular plugs in its ears and a bow ornament made of feathers associated with Tonatiuh the Sun god; the figure’s hands appear to hold the knife’s blade. After a sacrifice, the water from cleaning the blood-encrusted blade and handle, was believed to produce a magical drink mixed with peyote (Lophophora williamsi), a psychoactive drug that was believed to make one contemptuous of death. Such a mixture was given to Eagle and Jaguar warriors going off to battle, and to noble captives led to the techcatl, the sacrificial stone. Standing about three to four feet high, and two feet or so wide with a sloped top upon which a captive was firmly held on his back. It stood about a foot from the front edge of the upper terrace of a pyramid so that the lifeless body could easily be tipped off to tumble down to the pyramid threshold, the apetlatl. “Heart extraction was a common form of sacrifice and was one of the most dramatic and grisly skills ever created by the imagination of man. The subject is unpleasant but, without at least a cursory knowledge of this practice, one can never know the Aztecs” (Brundage, 1979:215).

The sacrificial victim was forcefully brought up the pyramid’s steps by strong temple guards. On the Great Temple upper terrace, facing Huitzilopoltchli, the victim was met by the high priest and the priest-executioner. He was then forcefully stretched and held spreadeagled on his back on the techcatl by temple attendants (calmecacs). For religious sacrifices six souls were tasked to help release the seventh through the pain of deliverance. They were the five temple attendants, who each held the victim’s arms, legs, and head, the executioner was the sixth, and the sacrificed, the seventh soul. This symbolic order answered to the four Tezcatlipocas, lords of the four cardinal directions, together with those of the zenith and the nadir, with the victim on the techcatl at their intersection. Prayers and singsong incantations to the gods were attended with a low drumbeat.

Upon completion of invocations, the priest-executioner holding the sacrificial knife (nahui tecpatl), cut a deep eight-to-ten-inch lateral gash below the ribs on the left side of the rib cage. The screams of fear and pain coming from the victim were believed to please the deity. The priest then forcibly put his hand in the gash and, seizing the beating heart, ripped it out of the chest. The blood from the severed aorta and arteries gushed forcefully over the priest and his attendants. The high priest then lifted the heart above his head and sung praises to the god to whom the sacrifice was dedicated, attended by now louder drumbeats and conch shell trumpets. The heart, offered to the Sun was then thrown in a carved stone bowl (cuauhxicalli), shaped on the belly of the reclining stone statue of a man leaning on its elbows (chac mool); “later the heart was cooked and eaten by the priests” (Brundage, 1979:217). Once the heart was removed, the body was shoved from the blood-drenched sacrificial stone down the pyramid steep stairway of the pyramid and allowed to tumble to the bottom. There, it was seized by temple guards. The head was cut and taken to join others on the large skull rack (huey tzompantli), a tall rectangular structure erected on the plaza facing the Great Temple. The body was then cut to pieces and select parts were shared in a ritual cannibalistic feast by the captor (tlamanih), his family, and friends; a femur was given to the captor who hung it in his house as proof of his valor.

The skull rack facing the Great Temple was 115 long by 40 feet wide. On its top was erected a forty-plus foot high scaffold of wood poles connected by a series of smaller horizontal section of wooden crossbeams. The skulls had the skin and hair removed, except for those of nobles and army officers. They were then displayed on the tzompantli by punching holes through skull temples where the crossbeam pole was inserted. Display of skulls of war captives and other victims was meant to impress citizens and visitors alike. When the tzompantli ran out of room, old skulls were simply discarded. Why display only skulls and no other body parts? In ancient cultures the head, skull and brain were one and the same. It was perceived as the seat of physiological and emotional vitality, the locus of identity and social status.

The head was then believed to be the portal to the sacred and to life cycles. The central plateau of Mexico ancient records drawn by local people, point to thousands of sacrifices taking place each year in mid to large urban areas. In Cholula with its unusual number of temples, hundreds were sacrificed annually (Torquemada.II,120 – Acosta, 1962,). The great skull rack structure (tzompantli) in Tenochtitlan’s Great Temple precinct, was flanked by two tall towers in which were embedded hundreds of skulls. Between the towers the enormous lattice work of wood beams held thousands of skulls.

Taking war captives (yaoyotl) was very important to Aztec warriors. For common soldiers, social aspirations were tied to attaining emblematic status of “butterfly” (papalotl) by capturing four enemies for sacrifice, which would result in a promotion to officer rank. All the actors on a battle ground were aware that their foremost aim was to capture rather than kill the opponent. Enemies seriously wounded were dispatched on the spot, while others were taken behind the front line, by dedicated teams. Their hands were tied behind their backs and a wood collar (cuauhcozcatl), was fastened around their neck, and linked to a long rope tied on which other captives (maltin) were also tied. At the end of the battle, every enemy captured was brutally driven to the city limits where he was recorded and credited to his captor. Once inside the city, however, the captives were treated kindly and with deference, because, from this moment on, they were no longer captives or slaves but recognized as full-fledged Aztecs citizens, not foreigners. All their needs were met, and they were offered sumptuous garments, fine food, drink, and women, since as citizens, they were now the god’s properties preordained for sacrifice. For months they paraded in the streets, attended popular events, sang, danced, and were housed in nobles’ quarters. Civil servants, merchants (pochteca) and other notable people bought slaves they donated to their temple for sacrifice to their select deities. The Aztecs could not conceive of gods and their welfare without sacrificing their own, not foreigners, for these gods were their gods, not the gods of others. As noted by Garcia Icazbalceta, “no slaves were taken in the wars of these natives, for they kept them all for sacrifice, and such formed the majority of those sacrificed in the land. Few except those taken in war were sacrificed, for which reason wars were continual” (1824-1894).

Sacrifices increased with time, and Flower Wars (xochiyaoyotl) were dedicated to capture victims in time of peace. These so-called wars did not aim to gain political, military, or economic benefits, but to secure offerings for the gods. The parties fought under a set of agreed upon rules, among which was the presence of an equal number of well-trained fighters on each side. According to Ixtlilxochitl (1500-1550), a lord from Texcoco, the rationale for the Flower Wars arose in response to another enduring crop failure and consecutive famine due to a severe drought (1450-1454). According to Ixtlilxochitl, the high priests of the Triple Alliance, Tenochtitlan, Texcoco and Tacuba said that the flayed one Xipe Totec, the god of nature, was angry, and to placate his ire it was necessary for the affected communities to supply victims. Those, such as in Tenochtitlan, Texcoco, Tlaxcala, Cholula and Huijotzingo, among other cities, were mandated to obtain human sacrifices to appease the gods with lives and especially for the war god Huitzilopotchli patron of the state. In his old age, Tlacaelel referred to the Flower Wars as a military “fair” or “market,” arguing just as merchants went to distant places to purchase luxuries, the god accompanied the army to the Flower War to purchase the food, and drink he coveted. Sacrificed knights were understood to be the god’s food and blood, or the currency with which to purchase food for the deity (Assig, 1988).

The important site of the rain god Tlaloc, beside its sanctuary atop the Great Temple next to Huitzilopotchli’s at Tenochtitlan, was on the Tlaloc Peak (Tlalocatépetl) a 3,500-feet-high mountain on the eastern rim of the Valley of Mexico situated at the end of a forty-four miles road connecting the two places of worship. The Tlaloc Peak is located directly east of the Great Temple, in-line with classic Aztec architecture with sunrise, for the Mexica designed everything to cosmological directions. To appease the gods and deities of the water world and rain destructive forces, babies, and children up to eight years old were sacrificed there during dry periods until rains started. Young children were joyfully carried on open litter to the sanctuary atop the peak. At dawn for the Huey tozoztli celebrations, little boys and girls were decapitated to honor the gods Cinteotl, Chicomecoatl, Quetzalcoatl, and Tlaloc. Sacrifices also included starvation of the little ones when they were left in a small, sealed cave in which they slowly died. (Berrelleza, Torre Blanco – arqueomex. 1998:31). In 1980, in Mexico City’s Great Temple, at the northeast corner of Tlaloc’s temple, “Offering.#8” was uncovered where were found the decapitated remains of thirty-eight children of both genders aged two to seven years, sacrificed at the time of the 1450-1454 famine. Together with the remains were found turquoise disks, a Tlaloc effigy, jade necklaces, and other semi-precious jewels (Duverger, 2007:618). At the time, the depth of beliefs was so deep-seated in people’s mind and heart that it overcame elemental compassion for one’s own. In Mesoamerican cultures, in time of collective crisis, such as persistent droughts and repeated food shortage, a community would sacrifice its best and most cherished, not the sickly or the maimed. Sacrificial victims had to be able, in their prime, and the younger the better, for the gods would not accept anything less.

In other Mesoamerican cultures there were also numerous secular and religious holy days that required human sacrifices believed to pacify the deities of the cosmic order. But they never reached the extent found with the Aztecs. The constant emotional turmoil of endless wars drove common folks to suicide as found in codices, that show people strangling themselves. Were the people moved by deep religious convictions which required them to create public and private elaborate forms of individual spiritual cleansing and penance? A cursory reading of ancient texts in the nahuatl language, as Brundage points out, reveals the terrible anguish and fear of individuals because of offences against religious or moral laws (1979:186). For this reason, perhaps, collective cleansing events took place at dedicated times.

Prominent in the Aztec spiritual universe, was the end of the fifty-two-year calendar round associated with the 260-day sacred calendar (Tonalpohualli), and the 365-day agricultural calendar (Xiupohualli). The two-time cycles together created the 52-years Aztec “century” associated with the putting out and rekindling of fires throughout the empire. At that time, fires on temples and homes were extinguished. Ritual cleansing together with self-bloodletting by parents and children took place in each household. Ceramic bowls and plates, stone jars and cooking utensils were broken, for they were believed to carry the essence of the old cycle. Huehueteotl (aka Xiuhtecuhtlil) the lord of fire, was celebrated throughout the year but especially at the end of the fifty-two years cycles. For Huitzilopochtli was said to be in a constant struggle with darkness and required nourishment in the form of sacrifices to ensure the sun would survive the cycle of fifty-two years, which was the basis of many Mesoamerican myths. At that time, it was believed that the new fire ceremony would forestall the end of the Fifth Sun for it represented the shift from one time cycle to the following. Then, priests marched in solemn procession up the extinct Huixachtlan volcano to wait for Orion’s belt, called “the fire drill” to rise over the mountain; then a man was sacrificed. The victim’s heart was ripped from his body and a ceremonial hearth was lit in the cavity of the chest using the hand drill method to generate the sacred flame. A large wood pyre was then lit from that flame and torches were carried on pine sticks by runners to light the fires on temples in Tenochtitlan and beyond. The fires were also lit in homes and all family members drew blood anew from their nose or ears, and threw the blood-stained rags into the new fire, the smoke carrying their pleas and hopes to the gods. At dawn, the entire populace of a city or town would go to nearby bodies of water to wash and cleanse themselves of past anguish and despair.

It was during the reign of the eighth Tlatoani, Ahuitzol (1486-1502), that sacrifices knew no bounds. Ahuitzol inherited the throne after the short and weak rule of Tizok (1481-1486), who left serious problems unsettled with allies and foes alike, that required swift and forceful resolutions. Reasserting Aztec power was a major concern of the nobles for they depended on the income from Tenochtitlan’s tributaries, and it must have been a matter of significant concern for Ahuitzol as well. Tenochtitlan could ill afford another weak leader, and the fate of any such leader would probably be swifter than Tizoc’s but equally final (Assig, 1988:204). Upon his crowning Ahuitzol marched first into the Huastec region which had rebelled against Tenochtitlan but quickly came to its senses to avoid extermination. Then the army marched and conquered Cuextecs, Xolotan, Xiuhcoac, Tochpan, Tetzapotitlan, Nauhtlan and other city states (atlepetl), whose defenders were no match for the Aztec army. Many captives were slain on the field of battle, while thousands were captured and carried away to be sacrificed for the dedication of the sixth remodeling of the Great Temple in 1487. Ahuitzol’s coronation ceremony was treated with disdain by enemy states after Tizok’s tenure. The Tlatoani brutal military campaign, however, led rulers of allied and enemy cities alike to hurriedly flock to the temple dedication ceremony. To eradicate Tizoc weakness with friends and foes alike, Ahuitzol put on a frightening display of military power unprecedented in size with hundreds of captives reported sacrificed each day for weeks. The main beneficiary of the sacrifices was the god of war Huitzilopochtli, while other deities were provided with sacrificial victims on other temples.

The killing of so many did not allow time for a swift cut by the priests to retrieve the heart. Gone was society’s amity toward the prisoners that had prevailed when they were received at the city’s gates. The cries of pain and screams of terror arising from many temples kept residents shaken long after the killings stopped at nightfall. By midday, the temple guards had a hard time bringing the screaming and fighting victims up the temple’s steep slippery stairs, drenched as they were with blood. Because of the large number of victims, these were lined up in the streets leading to the temples to wait for execution, their hands tied behind their back and linked together by a rope passing through their nose septum (Assig, 1988:205). With the Aztecs reputation greatly restored through fear, Ahuitzol eased his control over internal matters.

Many cities received their newly appointed rulers in 1486, but others were not permitted home rule until 1488, while still others were deferred until 1493. On August 13, 1521, with the Aztec defeat at the hands of men from another world, the Sun set on the last Tlatoani, Moctezuma.II Xocoyotzin (1502-1520) and the ancient gods. Then another sun rose for the Mexican people.
