From a philosophical-political approach to culture isolated from the assumptions of a modern-colonial-capitalist space-time, this essay examines the production of diverse spatio-temporal regimes. Museums, as emergent products of the spatio-temporal device of modern exhibition, stress the tradition-transmission relationship. Tradition implies an operation of separation that sacralizes a territory and a historical narrative --even when shown as secularized-- while unifying, stabilizing and hierarchizing the version of an abstract, absolute, progressive, linear space-time over multiple spaces and times which it intends to proscribe. This does not occur without an intrinsic relationship with transmission as a process that includes an impossible point of closure based on which the possibility of change, which tradition seeks to control, rests. Based on a case study of museification processes associated with the 100th Anniversary of the city of Río Grande (Tierra del Fuego, Antarctica and South Atlantic Islands, Argentina), this essay explores four spatio-temporal regimes, and identifies several operations (profanation, inoperability, others) dismantling the spatio-temporal hierarchies that fix tradition. In this sense, supplementation process as the thought of the alteration, that is, change in terms of event occurrence, stands out. Supplementation thus involves an emancipatory thought in action, which dismantles the hierarchies and inequalities in the processes of museification linked to modernity.
