There is reason to believe that the Incas used a zodiac with twelve signs, corresponding with the months of their solar year. The gold plates which they wore on their breasts were stamped with features representing the sun, surrounded by a border of what are probably either zodiacal signs or signs for the months. Whether the ecliptic, or huatana, was thus divided or not, it is certain that the sun’s motion was observed with great care, and that the calendar was thus fixed with some approach to accuracy.[1186] The year, or Huata, was divided into twelve Quilla, or moon revolutions, and these were made to correspond with the solar year by adding five days, which were divided among the twelve months. A further correction was made every fourth year. Solar observations were taken and recorded every month.
The year commenced on the 22d of June, with the winter solstice, and there were four great festivals at the occurrence of the solstices and equinoxes.[1187]
The celebrations of the solar year and of the seasons, in their bearings on agriculture, were identical with the chief religious observances. The Raymi, or festival of the winter solstice, in the first month, when the granaries were filled after harvest, was established in special honor of the Sun. Sacrifices of llamas and lambs, and of the first-fruits of the earth, were offered up to the images of the Supreme Being, of the Sun, and of Thunder, which were placed in the open space in front of the great temple; as well as to the huaca, or stone representing the brother of Manco Ccapac, on the hill of Huanacauri. There was also a procession of the priests and people as far as the pass of Vilcañota, leading into the basin of Lake Titicaca, sacrifices being offered up at various spots on the road. The sacrifices were accompanied by prayers, and concluded with songs, called huayllina, and dancing. Then followed the ploughing month, when it is said that the Inca himself opened the season by ploughing a furrow with a golden plough in the field behind the Colcampata palace, on the height above Cuzco.
The question here arises whether human sacrifices were offered up, in the Inca ritual. This has been stated by Molina, Cieza de Leon, Montesinos, Balboa, Ondegardo, and Acosta, and indignantly denied by Garcilasso de la Vega. Cieza de Leon admits that there were occasional human sacrifices, but adds that their numbers and the frequency of such offerings have been grossly exaggerated by the Spaniards. If the sacrifices had been offered under the idea of atonement or expiation, it might well be expected that human sacrifices would be included. Under such ideas, men offered up what they valued most, just as Abraham was prepared to sacrifice his son, as Jephthah dedicated his daughter as a burnt-offering to Jehovah, and as the king of Moab sacrificed his eldest son to Chemosh.[1188] But, except in the Situa, when the idea was to efface sins by washing, the sacrifices of the Incas were offerings of thanksgiving, not of expiation or atonement. The mistake of the five writers who supposed that the Incas offered human sacrifices was due to their ignorance of the language.[1189] The perpetration of human sacrifice was opposed to the religious ideas of the ancient Peruvians, and formed no part of their ceremonial worship. Their ritual was almost exclusively devoted to thanksgiving and rejoicings over the beneficence of their Deity. The notion of expiation formed no part of their creed, while the destruction involved in such a system was opposed to their economic and carefully regulated civil polity.[1190]
The second great festival, called Situa, was celebrated at the vernal equinox. This was the commencement of the rainy season, when sickness prevailed, and the object of the ceremony was to pray to the Creator to drive diseases and evils from the land. In the centre of the great square of Cuzco a body of four hundred warriors was assembled, fully armed for war. One hundred faced towards the Chincha-suyu road, one hundred faced towards Anti-suyu, one hundred towards Colla-suyu, and one hundred towards Cunti-suyu,—the four great divisions of the empire. The Inca and the high-priest, with their attendants, then came from the temple, and shouted, “Go forth all evils!” On the instant the warriors ran at great speed towards the four quarters, shouting the same sentence as they went, until they each came to another party, which took up the cry, and the last parties reached the banks of great rivers, the Apurimac or Vilcamayu, where they bathed and washed their arms. The rivers were supposed to carry the evils away to the ocean. As the warriors ran through the streets of Cuzco, all the people came to their doors, shaking their clothes, and shouting, “Let the evils be gone!” In the evening they all bathed; then they lighted great torches of straw, called pancurcu, and, marching in procession out of the city, they threw them into the rivers, believing that thus nocturnal evils were banished. At night, each family partook of a supper consisting of pudding made of coarsely ground maize, called sancu, which was also smeared over their faces and the lintels of their doorways, then washed off and thrown into the rivers with the cry, “May we be free from sickness, and may no maladies enter our houses!” The huacas and malquis were also bathed at the feast of Situa. In the following days all the malquis were paraded, and there were sacrifices, with feasting and dancing. A stone fountain, plated with gold, stood in the great square of Cuzco, and the Inca, on this and other solemn festivals, poured chicha into it from a golden vase, which was conducted by subterranean pipes to the temple.
The third great festival at the summer solstice, called Huaracu, was the occasion on which the youths of the empire were admitted to a rank equivalent to knighthood, after passing through a severe ordeal. The Inca and his court were assembled in front of the temple. Thither the youths were conducted by their relations, with heads closely shorn, and attired in shirts of fine yellow wool edged with black, and white mantles fastened round their necks by woollen cords with red tassels. They made their reverences to the Inca, offered up prayers, and each presented a llama for sacrifice.[1191] Proceeding thence to the hill of Huanacauri, where the venerated huaca to Ayar Uchu was erected, they there received huaras, or breeches made of aloe fibres, from the priest. This completed their manly attire, and they returned home to prepare for the ordeal. A few days afterwards they were assembled in the great square, received a spear, called yauri, and usutas or sandals, and were severely whipped to prove their endurance. The young candidates were then sent forth to pass the night in a desert about a league from Cuzco. Next day they had to run a race. At the farther end of the course young girls were stationed, called ñusta-calli-sapa,[1192] with jars of chicha, who cried, “Come quickly, youths, for we are waiting!” but the course was a long one, and many fell before they reached the goal. They also had to rival each other in assaults and feats of arms. Finally their ears were bored, and they received ear-pieces of gold and other marks of distinction from the Inca. The last ceremony was that of bathing in the fountain called Calli-puquio. About eight hundred youths annually passed through this ordeal, and became adult warriors, at Cuzco, and similar ceremonies were performed in all the provinces of the empire.
In the month following on the summer solstice, there was a curious religious ceremony known as the water sacrifice. The cinders and ashes of all the numerous sacrifices throughout the year were preserved. Dams were constructed across the rivers which flow through Cuzco, in order that the water might rush down with great force when they were taken away. Prayers and sacrifices were offered up, and then a little after sunset all the ashes were thrown into the rivers and the dams were removed. Then the burnt-sacrifices were hurried down with the stream, closely followed by crowds of people on either bank, with blazing torches, as far as the bridge at Ollantay-tampu. There two bags of coca were offered up by being hurled into the river, and thence the sacrifices were allowed to flow onwards to the sea. This curious ceremony seems to have been intended not only as a thank-offering to the Deity, but as an acknowledgment of his omnipresence. As the offerings flowed with the stream, they knew not whither, yet went to Him, so his pervading spirit was everywhere, alike in parts unknown as in the visible world of the Incas.
A sacred fire was kept alive throughout the year by the virgins of the sun, and the ceremony of its annual renewal at the autumnal equinox was the fourth great festival, called Mosoc-nina, or the “new fire.” Fire was produced by collecting the sun’s rays on a burnished metal mirror, and the ceremony was the occasion of prayers and sacrifices. The year ended with the rejoicing of the harvest months, accompanied by songs, dances, and other festivities.
Besides the periodical festivals, there were also religious observances which entered into the life of each family. Every household had one or more lares, called Conopa, representing maize, fruit, a llama, or other object on which its welfare depended. The belief in divination and soothsaying, the practice of fasting followed by confession, and worship of the family malqui, all gave employment to the priesthood.
