“Sortir Au Jour” (Coming Forth By Day) is a video installation gathering two films of 45 minutes, which tells the story of a world slowly loosing its structure. This artistic production is the fruit of a research in which I do a crossed reading of two narratives: The funerary rites of ancient Egypt on the one hand, and the concept of thermodynamic entropy on the other. This crossed reading constitutes the transdisciplinary shift of the project, in that I learn from both mythological and scientific disciplines and their respective methods in order to extract and shape a third narrative; the research of a scientific understanding and the moral conceptions from ancient Egypt are redirected towards the creation of a model of poetic nature. Playing with concepts of unicity, duality and multiplicity, of sameness and otherness, “Sortir Au Jour” proposes the hypothesis of a tendency towards an undifferentiated state, which would take place in both physical and metaphysical worlds. The transdisciplinary approach which builds the narrative is combined with a multidisciplinary practice which gathers sound art, text, dance, performance and sculpture, all of them included within the video format.
