“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. In “Sortir Au Jour”, the audience is invited to enter a space in which two films are screened at each end of the room. The soundtracks of the films are displayed through two distinct sets of both loudspeakers and headphones, in a manner which allows them to be either isolated or overlaying – this play with the porosity between the two parts of the installation resonating with the concepts at stake in the project. The characters and objects appearing throughout the films are born from the hybridization of symbols and concepts from physics and mythology (divinities, equations, prayers, thought experiments, deceased traveling towards afterlife, particles…). Oscillating between acceptance and resistance, they undergo the force of an increasing entropy: Their bodies merge, their words lose their performative power as their meanings extend, the distribution of their roles is confused, their architecture crumbles and their individualities diffuse; the unique reflects into otherness, and the sameness grows into multiplicity. Implicitly, this story invites the audience to rethink their own individuality and relation to the other, the collective or the environment from a shifted perspective; a perspective offering the openness of poetry, freed from the weight of models based on the opposition of good and evil or of true and false. “Sortir Au Jour” is a travel between the immense and the small, its very construction drawing a parallel between the tiniest particles and the realm of the greater gods of ancient Egypt. Story of the universal and of the intimate simultaneously, the narrative spreads vertically through various scales and levels while spreading horizontally in time. The discursive and sensible aspects of “Sortir Au Jour” (in other words research and practice) have been developed in a constant back and forth during the six semesters of my studies in the Master Transdisciplinarity. Those two aspects have been reacting to each other and brought into a dialogue: ideas have shaped forms as much as forms have shaped ideas. This porosity appears particularly clearly in the written part of the master’s work: documenting the latter and reflecting on it, this publication is directly connected with the video installation; simultaneously, it has its own autonomy as a hybrid format between artistic research and production, in which the theoretical is infused with the poetic, the theoretical grows through fiction and the visual nourishes the thinking process.
