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]
