The article proposes to inquire the heritage studies according to an alternative view. Elements as agency, materiality and ontology are fundamental, insofar as that notion is accompanied by factors as the destruction or the wear, the conservation or the restauration. In this sense, this paper deconstructs the movable heritage, which is feasible the move of fragments in diverse areas, as exponent of the modern objetivation. Also, it sets out at what extent these practices and the materiality influence the construction of (...) epistemological discourses and disciplinarian categories relative to museums. Finally, it exposes a specific case: the introduction of material rests from the Jesuitical-Guaraní Missions to La Plata Museum, at the end of the 19th century. (shrink)
