Abstract : This research intends to analyze the long-term museological exhibitions of the Museu do Homem do Sambaqui Padre João Alfredo Rohr, S. J. (Florianópolis Santa Catarina) e do Museu Diocesano dos Povos da Floresta (Juína Mato Grosso). Both institutions are run by religious organizations: the Jesuits are at the head of the first one and in Juína (MT) there is a management that complies with the diocesan precepts. In this study, I investigate the history of the foundation of these museological spaces, of the categories that structure the conceptual bases of their exhibitions and the tensions that pass through the choices of the memories required for these preservation spaces. The analysis explores how indigenous objects, in particular the sophisticated head feather pieces with reference to the Rikbaktsa - known as myhara garlands - are presented to the public in these museum arrangements. Following the myhara in this museum entanglement showed me that these paths are constituted by humans, animals, things, power (politics), memories and histories, Amerindian and Western cosmologies among others - and thus opening a more complex understanding of these dimensions engage all these feather pieces in the world.
