This dissertation is based on the fieldwork performed at an indigenous squatter situated at Maracanã district, Rio de Janeiro. Full of interethnic exchanges, the Instituto Tamoio dos Povos Originários is a true urban-indigenous village, as the residents define themselves. Ethnic groups as Pataxós, Fulni-ôs, Apurinãs e Guajajaras share the edifice, that was first seat of the brazilian Indigenous Museum, founded by the anthropologist Darcy Ribeiro. At the same space, a shaman woman, from Fulni-ô and Caririr-Xocó tribes coordinate an house of prayer, frequented by different urban groups. Though the house of prayer declares indigenous filiation, its activities can be better described as magical, subject that is broached in the entire text of the dissertation.
