This lecture aims to explain the processes of decolonial resistance in Latin America. The realization of this aim implies recognizing its approaches and recovering the concepts in art, specific to the indigenous communities, nucleated in the community practices of resistance in defense and care of the territory, land, and nature. Taking the investigative perspective of the Multimodal and Multimedia Critical Discourse Studies (MMCDS), it will explore the process of decoloniality that emerges from the break with the principles that capitalism and neoliberal politics impose; therefore, it is a question of surveying the rationalization of the social, political, cultural, transversal areas through the care of nature. The object of detailed analytical scrutiny will constitute a collection of artistic works that Carlos Jacanamijoy, a Colombian painter of native South American origin of the Indigenous Inga people, created. Special attention will be devoted to his paintings from the years between 2007 to 2015, in which he proposes to reveal the sense of naturalness linked to ancestral cosmology. It is assumed that the communicative purpose of managing collective social action is to be exhibited through the samples of art, especially when integrating decolonial axiology and epistemology. What is the chosen sample's main criterion is how Latin American identity is formulating the rupture with coloniality, and its representations of nature in the socio-economic, political-cultural, and ethnic order. The selected pieces of the exhibition are characterized by having a thematic unity, being multimodal, and circulating through digital technologies. Accordingly, the analytical-interpretative approach undertaken in the lecture will allow the participants of the 2024 IASS-AIS Congress in Warsaw to infer that the artistic discourse seeks to deconstruct the hegemonic order and the dominant cognitive imperialism in the region by highlighting the representation of the meaning of the notion of ancestry in the context of decoloniality.
