Society-MATACO The Mataco (Mataguayo) are an American Indian ethnic group located in the western part of the Argentine-Bolivian Gran Chaco, between the Rio Pilcomayo and the Rio Bermejo. They are divided into three main regional groups: (1) the Mataco-Vejos, the most acculturated group, who live in the northern Argentine, bounded on the west by Tartagal and on the south by the Rio Bermejo; (2) the Mataco-Guisnay, who inhabit the right bank of the Pilcomayo, about thirty miles south of Fortin Guachalla; and (3( the Mataco-Noctenes, the least acculturated group, who occupy the triangle formed by the lines connecting the villages of Yucuiba, Villa Montes, and Crevaux. In contrast to other Chaco groups, the Mataco have had more exposure to Whites and they have exhibited a remarkable adaptability to the new situations created by contact. Greenberg (1966) classifies the Mataco language within the Macro-Panoan subfamily of the Ge-Pano-Carib language family. Dialectual differences occur among the three regional groups. The Choroti, the Ashluslay, the Maca, and the Lengua-Enimaga peoples are all closely related linguistically to the Mataco (Steward and Faron 1959: 22, 415). There is very little information available on Mataco demography. An early missionary account by the Franciscan Father Jose Cardus, published in Barcelona in 1886, estimated that the Mataco population around that time was 20,000 (Pelleschi 1896: 42-43). Current population figures are unavailable, but it is probable that a few thousand Mataco Indians survive today. Next to the Toba, they are the largest of the Argentine Chaco groups. Because of the inhospitable geographic and climatic conditions of the Gran Chaco, exploration of this area was slow and sporadic. The western Chcao in particular is noted for its aridity, soil salinity, very hot summers, and locust plagues. Wild plant foods were generally the basis of subsistence, but a vital supplement was provided by seasonal fishing in the Bermejo, Pilcomayo, and Salado Rivers (Steward and Faron 1959: 413-16). The Mataco are primarily hunters and gatherers. Various roots and seeds, wild honey, and wild fruits are collected, the most important food source being the wild fruit, especially algarrobo, which is preserved and stored for later use. A beer used in the practice of magic is made from algarrobo. Because of unfavorable ecological conditions, there is limited agricultural activity. Beans, watermelons, manioc, and maize are grown, but the most important crop is squash. Domesticated animals include sheep, goats, dogs, and fowl. Fishing is the most important economic activity. Fish is the favorite food of the Mataco, and any surplus fish is dried and stored. Fishing with nets is common. The Mataco hunt tapir, wild pig, and various small animals with bows and arrows. Tools are made from bone and shell. Stone is not available. The Mataco weave fabrics, nets, and baskets; they also make cereamics. The Mataco are seminomadic A village is always located near a convenient water supply, pasturage, and wild fruit trees. The village usually consists of 6 to 12 houses arranged in a circle around an open area, which is used for sheep and goats or for games or ceremonies. The traditional Mataco house is a circular hut, with a frame made from saplings, canes, etc. and covered with rushes, grass, or palm leaves. In traditional Mataco villages there is no real political authority. The chief of the village is selected for his wisdom by the village elders. A war chief is selected whenever the village goes to war against another village; when several villages are involved in warfare, a council of allied chiefs is formed. The cacique system is found in acculturated Mataco villages. The cacique has greater power, especially judicial, than the traditional chief does, and he acts as an agent in dealing with the Whites. The cacique also mediates differences between local groups. Village exogamy is practiced. Girls usually marry between the ages of 12 and 14; the final decision regarding the choice of the husband is left to the girl's mother. The mataco also have the custom of bride service. After this service has been completed and until their first child is born, the married couple live in the husband's village. Thereafter, residence is matrolocal. Descent is matrilineal, and kinship terminology is of the Hawaiian type. Ceremonies are important to the Mataco. Some of the ceremonies performed are associated with disease, hunting and fishing, agriculture (especially to ensure the algarrobo harvest), religion, weddings, and puberty for girls. During ceremonies, dancing, drum playing, drinking, and chanting are all thought to ward off evil spirits. The Mataco pray to guardian spirits for supernatural aid. In ceremonies performed to prevent disease, the Mataco tattoo their bodies using soot or ashes as pigment. Bleeding and scarification, as well as the ownership of sacred objects, are also believed to be effective in preventing disease. The Mataco believe that evil spirits manifest themselves in the form of disease in humans as the result of witchcraft. To cure disease, the shaman is called upon to dance, make noise, suck out the evil object, and use spells and charms. Herbs, especially in poultices, are also used to cure disease. The Mataco believe that there is an upper world, composed of the earth and the sky, and a lower world, where the dead live. They also believe that spirits inhabit many natural objects, plants, and animals. Other types of spirits, "free floating" spirits, are associated with thunder and lightning, etc. Some of these spirits are good, but others are evil.
