This dissertation starts from the Jacques Rancierè s visibility regimes and from the Didi-Huberman s concept of montage to the analysis of the text Desmedida, 2006, by Ruy Duarte de Carvalho. The central objective is to evidence this artistic production like an instrument of interventional writing, inspired by three different logics: political, native communities and cinematographic. For that purpose, it s noted that artistic manifestation as a space of resistance, reaction and confrontation to discursive images generated with the intention of limiting existences in different times of the colonial domination, as well as the contemporary colonialities.
