The projection and screens in this installation are access points meant to connect the present to an ancestral past. Evoking the ritualism of Aztec cosmology, this experience recalls lumbreras – circular excavation holes in archeological sites, such as the recently found Tzompantli (skulls ceremonial rack) at the Templo Mayor in Tenochtitlan (Mexico City). The use of obsidian crystal as a nuclear filter in the chamber is also essential. Through the obsidian glass we glimpse the celestial dance of the suns and moons as well as the agitation of the countryside and the outburst of the landscape, but it is also the look that the dark obsidian mirror returns to us.
