An artistic and theoretical investigation on fossil fuels, industrial agencies in nature and their reflections on social structures and power systems. With the goal of inspecting the operation of the arts in the cosmopolitical battles of the present especially in the new geological epoch called Anthropocene – the article analyses performance and sculpture as practices that could materialize crossings of temporalities and dimensions, reflecting on the encounter between the scales of the human and the planet. Bruno Latour’s Actor-network theory is a departing point for conceptual speculations, developed with the freedom and experimentation that moves artistic research.Une étude artistique et théorique sur les combustibles fossiles, les assemblages industriels dans la nature et ses réflexes dans les structures sociales et les systèmes de pouvoir. Afin d’examiner le rôle des arts dans les conflits cosmopolitiques du présent – en particulier en ce qui concerne le nouvel âge géologique de l’anthropocène – l’article observe la performance et la sculpture comme des pratiques artistiques qui peuvent matérialiser les passages des temporalités et dimensions, en reflétant la rencontre entre les échelles l’humain et la planète. La théorie de l’acteur-réseau de Bruno Latour est le point de départ des articulations conceptuelles, dessinées avec la liberté et l’expérimentation caractéristiques de la recherche artistique.An artistic and theoretical investigation on fossil fuels, industrial agencies in nature and their reflections on social structures and power systems.
