A body sails through cosmic waters. Recovering a mythological imaginary of creation (a cosmogony) in which the Universe (and the Earth) are shaped from a promordial liquid, we evoke a myriad of creation myths, present, for example, in the Tucano culture (tribes from the northeast of Amazon river), the budism and hinduism. Embodying this imaginary, "On the cosmic night" presents a creative body, that dives into the primordial waters and that spreads, from the center – center of the self and center of the universe –, personifying the idea of center present on the mythology of creation. From a small particle of matter, the "cosmic egg", all universe eclodes. The chaos-cosmos dynamics, the implosion-explosion movement appear on the different gestures of the cosmic body, but are also questioned by the fragmentary presence of the images (slides). These reveal the exercise of fabrication of these images, mixing relations of scale and matter, introducing a paralel imaginary – of encenation –, which supports the project.
