Kamayurá

The Kamayurá are a Tupi-Guarani-speaking people of the Upper Xingu, in the Xingu Indigenous Park in Mato Grosso, Brazil; the name is also written Kamaiurá and Camaiurá in Portuguese sources. Their identity is bound to a particular body of water: their village stands near a lagoon called Ipavu, a name they gloss as 'great water', and they describe themselves as having always remained in that region. Povos Indígenas no Brasil records 710 people in 2020 (Siasi/Sesai). The demographic history is stark: Karl von den Steinen counted 264 in 1887; a measles epidemic in 1954 left 94 survivors; the population was 131 in the early 1970s, 355 in 2002 and 492 by Funasa's 2006 count. The recovery from 94 people is one of the clearest demonstrations of what the Xingu vaccination and health programmes achieved. The Kamayurá belong to the Upper Xingu multi-ethnic system, a society of peoples who speak unrelated languages — Arawak among the Wauja and Mehinako, Cariban among the Kuikuro and Kalapalo, Tupi-Guarani among the Kamayurá, plus Aweti and the isolate Trumai — but share a diet, a village form, a ceremonial calendar, marriage across ethnic lines and a network of specialised production. Their influence on the system is out of proportion to their numbers: the two ceremonies known region-wide and internationally, the Kwarup and the Jawari, are known by their Kamayurá names, and the Kamayurá are frequently treated as a cultural reference point for the Upper Xingu as a whole.

Kamayurá territory lies in the confluence region of the Kuluene and Kuliseu rivers in the Upper Xingu, within the Parque Indígena do Xingu in Mato Grosso, in the municipality of Canarana; their main village sits near the Ipavu lagoon, north of the Leonardo Villas-Bôas post. The setting is a mosaic of gallery forest, transitional forest and cerrado, cut by rivers and studded with lagoons and oxbow lakes, and the lagoon is as important economically as the rivers, providing fishing grounds close to the village. The park was created in 1961 as the Parque Nacional do Xingu, following the Roncador-Xingu expedition of the 1940s, and was the first large Indigenous territory demarcated in Brazil; it later passed to Funai's administration and today shelters sixteen peoples. Its structural flaw shapes Kamayurá life directly: the demarcation covers the middle and part of the upper basin but stops short of the headwaters, leaving the springs and upper courses of the rivers on private land outside the park, so that deforestation, agrochemical use and siltation upstream arrive downstream as degraded water. The year divides between a rainy season, when the rivers rise and fishing yields fall so that maize, papaya, squash, watermelon and stored manioc products carry the diet, and a dry season when water drops, fish concentrate, travel between villages becomes easy and the great inter-village ceremonies are held.

Kamayurá belongs to the Tupi-Guarani family, which makes it a relative of Guarani and of the historical coastal Tupi languages, and a linguistic outlier in a region whose other members speak Arawak and Cariban languages. Its presence in the Upper Xingu reflects a later arrival into an older Arawak- and Cariban-settled system. Povos Indígenas no Brasil describes the Kamayurá as maintaining their language while engaging increasingly with Portuguese. Multilingualism is normal rather than exceptional in a society where people marry across language boundaries, and the Kamayurá themselves acknowledge borrowing extensively from neighbours — dance steps, tobacco use, pottery technique, net-making, beiju preparation, flute construction and vocabulary — which is a striking case of a people describing its own culture as substantially acquired. A number of Portuguese loanwords are similarly acknowledged. Schooling and language work run through the park's education programmes: since 2000 young Kamayurá have taken part in the teacher training course run by the Instituto Socioambiental inside the Xingu Park, and the Escola da Cultura, supported by Funai, brings older men and women together with children and young people for instruction in dance, song, craft and oral history — an institution that functions as language transmission as much as cultural transmission. This session's sources gave no separate speaker count and identified no dedicated Kamayurá language documentation project comparable to the Kuikuro DOBES corpus; that is a gap rather than an absence.

Manioc and fish are the foundation. Men cut and burn the gardens; women harvest and carry out the processing chain, reducing the tubers to pulp and to settled starch, from which comes beiju, the flat manioc bread eaten several times a day with fish, with pepper, or dissolved into the drink known as cauim. Fishing is the main source of animal protein and is done year-round by several techniques: individual and family-scale fishing with nets, bows, traps and hooks, and collective operations in which a dammed stretch of water is treated with plant-derived stupefacients and most of the men of the village take part. Hunting is limited to birds and small animals, in keeping with the regional avoidance of most land game; captured harpy eagles are kept alive in the village for their feathers. Women and children gather collectively: honey, pequi, genipap, mangaba and tracajá turtle eggs, along with firewood. Pequi kernels are a ceremonial food distributed at the Kwarup. Maize, papaya, squash, watermelon and guaraná diversify the diet and matter most in the rainy season when fishing is poor. The Kamayurá are the region's recognised specialists in bow-making — now largely ceremonial since firearms arrived — and also in basketry, jatobá-bark canoes, sleeping hammocks and fishing nets, and house construction, which they trade into the regional network in return for Wauja pottery, Wauja and Mehinako salt and pepper, and Kuikuro and Kalapalo shell necklaces and belts.

Kamayurá material culture is organised by the regional exchange system, and their acknowledged specialities are things made from wood, fibre and cord rather than clay. Bows are the emblematic Kamayurá product; with the arrival of firearms their function has shifted from hunting to ceremony and exchange, but the craft has not been abandoned. Basketry, hammocks, fishing nets, jatobá-bark canoes and house-building expertise are all traded outward. Body painting uses the regional palette — the blue-black of genipap, the red of annatto, and white — applied in geometric designs and in animal, bird and fish motifs. Featherwork is elaborate, and the practice of keeping captured harpy eagles alive in the village indicates how seriously the supply of plumage is taken. Ceremonial equipment is an art form in its own right: the wooden Kwarup posts are painted and decorated by the families of the honoured dead, and masks, ornaments and instruments are made as part of ritual preparation. Contemporary work mixes industrial materials — glass beads, wool thread, metal tools — with native cotton, embira fibre, buriti palm and wood. The Escola da Cultura, supported by Funai, has craft instruction by elders as one of its explicit purposes. This session's sources did not identify individually named Kamayurá artists or collectives in the public record, and none are asserted here.

Kamayurá public life runs through the household group, headed by a morerekwat or house owner who coordinates its productive work, and through the village leader, the morerekwaratuwiap, whose authority rests on mediation, generosity and skilled formal speech rather than on command; succession is flexible and often contested. For dealings with the outside the Kamayurá created the Associação Mavutsinin, named after their culture hero, to develop community projects, of which the best documented is the Escola da Cultura, supported by Funai, where older men and women teach children and young people dance, song, craft and the histories of the people. Since 2000 young Kamayurá have taken part in the teacher training course run inside the park by the Instituto Socioambiental. The pressures are those of the Upper Xingu as a whole. The park's boundary excludes the river headwaters, so deforestation, agrochemical runoff and siltation from the soy and cattle frontier arrive as degraded water and depleted fisheries. Hydroelectric development on the headwater rivers has been fought collectively: from 2005 leaders of Xinguano peoples opposed the Paranatinga II plant on the Culuene, on the grounds that the stretch affected is sacred as the site of the first Kwarup; a court suspended the works but the plant was built by 2008. Kamayurá accounts of contemporary change describe machines, industrial food, clothing, schools, health units, medicines, football and recorded music as things to be selectively integrated rather than simply accepted or refused. Xinguano peoples have also joined the Y Ikatu Xingu headwater restoration campaign launched in 2004 and the Rede de Sementes do Xingu native seed network created in 2007.

Fibre and cord work is a Kamayurá speciality within the regional exchange system, and it is the domain in which they supply their neighbours. Sleeping hammocks and fishing nets are the principal products, made from native cotton, embira bast fibre and buriti palm fibre; the same materials go into carrying straps, cordage, bindings and the fittings of feather ornaments. Basketry is likewise a Kamayurá trade good. Girls learn the work during puberty seclusion, where the recorded instruction includes mat-weaving, net-making and food preparation, while boys in seclusion are taught arrow-feathering, basket-weaving and wrestling — so the fibre crafts are transmitted as part of becoming an adult rather than as an optional skill. Body ornaments made of worked fibre and feather are worn in ceremony, with adult male dancers wearing composed sets. Dye plants are the regional pair, genipap for blue-black and annatto for red, together with white clay, used on bodies and on worked objects. Contemporary work incorporates glass beads and wool thread alongside the native materials, and metal tools have replaced older ones in preparation. This session's sources did not give named forms for particular hammock types, arm and leg bands, or information on where Kamayurá fibre work is sold or exhibited beyond the regional exchange network, and those remain gaps.

The Kamayurá are not potters, and in the Upper Xingu that is a positive fact about the exchange system rather than a gap in their skills. Ceramics are the recognised speciality of the Arawak-speaking Wauja, and the Kamayurá obtain from them the pots and pans essential to cooking and, crucially, the large flat griddles on which beiju is baked — an item without which the staple food cannot be produced. The Kamayurá reciprocate with bows, hammocks, nets, basketry and canoes, and they also receive salt and pepper from the Wauja and Mehinako and shell necklaces and belts from the Kuikuro and Kalapalo. The dependency is mutual and deliberate, and it is one of the mechanisms that holds the multi-ethnic system together. One further detail complicates the picture: the Kamayurá themselves acknowledge having taken pottery technique, among other things, from their neighbours, which suggests some ceramic practice rather than none. This session's sources did not establish what the Kamayurá make in clay for their own use, if anything, and that is an open question for contributors.

Kamayurá music is the subject of one of the founding works of Brazilian ethnomusicology, Rafael José de Menezes Bastos's A Musicológica Kamayurá, presented as a master's dissertation in Brasília in October 1976 and first published by Funai in 1978, which argues that music is the organising logic of Kamayurá social life and of communication in the Upper Xingu generally, rather than an accompaniment to it. The central instruments are aerophones. The jakui — also written yaku'i — are the large flutes of the sacred flute complex, kept in the flute house on the plaza, played by men and not to be seen by women; the published description notes that three flutes play together, producing a heterophonic texture led by a central player who is always a recognised master of music. The uruá are paired raft flutes. Gourd rattles, maracás, accompany dancing, and rattles are sounded through the Kwarup. Song is attached to specific ceremonies and is led by masters; the Kamayurá themselves acknowledge having taken dance steps and flute construction from neighbouring peoples, which is consistent with music circulating through the same regional network as goods. Transmission runs through participation and through the Escola da Cultura, where elders teach dance and song to the young. This scaffold names the sacred flute complex and its instruments and does not assert content the sources do not document.

Two of the ceremonies known throughout the Upper Xingu carry Kamayurá names. The Kwarup, often written Quarup or Kuarup, is the mourning ceremony that honours the dead of high standing and formally closes the mourning period; it is also the ceremony that most visibly expresses solidarity among the peoples of the region, since several ethnic groups gather in one host village. Each honoured person is represented by a wooden log roughly a metre and a half tall, set in the plaza, painted and decorated by the family, with small fires lit before it. Over about two days people weep, sing, dance and wrestle to the sound of gourd rattles; guests are received with formal speech, food including pequi kernels is distributed, huka-huka wrestling matches are held and craft goods change hands. The ceremony dramatises a version of the creation of humanity. At the end the logs are taken to the river, releasing the dead and returning the mourners to ordinary life. Non-Indigenous visitors have been admitted to some Kwarup celebrations. Huka-huka is the Upper Xingu belt wrestling, a public contest between champions in which grappling and leg-hooking replace striking, trained for from boyhood. The Jawari, by contrast, stages distinction and rivalry rather than solidarity: it is a competitive festival of dart-throwing with a spear-thrower that channels aggression into sport and marks ethnic identity. Moitará is the formalised exchange encounter, held between houses within a village and between villages, with goods passing through leaders as intermediaries under an ethic of reciprocal obligation rather than profit. The jakui flute complex, kept in the tapuwí on the plaza and restricted to men, is named here and its interior not described. Puberty seclusion is a further formative institution, in which young people are withdrawn from public life and taught adult skills.

Kamayurá healing combines shamanic practice with a broad knowledge of plants, and it sits within the Upper Xingu framework in which serious illness is understood as the action of powerful non-human beings on the sick person. Specialist knowledge is held by shamans and is acquired over years through apprenticeship, seclusion and personal experience rather than open teaching; tobacco is central to practice, and its role is ritual and diagnostic. Plants are used in healing contexts, and that knowledge is the intellectual property of the community and its specialists. No plant parts, preparation methods, doses or plant-plus-method combinations appear here and none should be added — a firm safety line that also protects the community's rights under Brazil's Law 13.123/2015 on access to associated traditional knowledge. The intercultural interface is unusually well developed. The Projeto Xingu of the Escola Paulista de Medicina, now the Federal University of São Paulo, has worked in the park continuously since July 1965, when a medical team led by Dr Roberto Baruzzi arrived at Leonardo Villas-Bôas post at the invitation of Orlando Villas-Bôas. Immunisation was the founding priority, precisely because the 1954 measles epidemic had reduced the Kamayurá to 94 people and killed a large share of the Upper Xingu population overall. The project has since trained Indigenous health agents, runs a specialist outpatient service for Indigenous patients at Hospital São Paulo, hosts student placements in Indigenous health, and is treated in the public health literature as a reference model. Day-to-day services run through the Xingu Indigenous Health District. No biopiracy case specific to the Kamayurá surfaced in this session's sources.

The Kamayurá village follows the Upper Xingu model: large houses arranged in a circle with rounded roofs thatched in sapé grass, around a swept central plaza called the hoka'yterip. The plaza is the public and masculine domain, where announcements are made, huka-huka wrestling takes place and ritual is staged, and on it stands the flute house, the tapuwí, where the jakui flutes are kept and played, with access restricted to men. The houses are the domain of women and children. Each is occupied by an extended family group whose sections have their own space while sharing central hearths and food storage; hammocks are slung from the internal frame. The household is a productive as well as a residential unit, headed by a morerekwat, the house owner, who coordinates its work. Residence after marriage begins with the couple living with the wife's family and later moves to the husband's household, so the composition of a house changes through the life cycle. House-building is one of the recognised Kamayurá specialities within the regional exchange system, which is a notable fact about a society where technical competences are distributed between peoples. Change has come through industrial materials, metal tools and the presence of school and health buildings in the village, but the ring of houses around the plaza with the flute house at its centre remains the working plan of Kamayurá social life rather than a preserved form.
