Leda Maria Martins’ keynote explores Black and Indigenous cosmo-perceptions in Brazil, as ways of understanding the universe and humanity’s place within it. Cosmo-perceptions, she argues, manifest in both cultural events and the smallest gestures of daily life—in silences, vibrations, and sensations—and shape how societies and subjects come into being. She highlights epistemological principles through which land, territory, and life are conceived as expressions of the sacredness of the environment. Knowledge, in this sense, is not only safeguarded in archives, monuments, or other official sites of memory but continually recreated in what she calls ‘environments of memory’: the oral repertoires, gestures, and embodied habits through which it is transmitted. In Martins’ work, time is experienced through the body, particularly through performance practices like dance, theatre, and rituals. These embodied actions serve as vessels for memory and knowledge, making space for non-linear temporalities. They inscribe knowledge in performance, dissolve the boundary between orality and writing, and work toward dismantling colonial structures, while reactivating ancestral practices effaced by them.
