From this “fake sun” a rope hangs to the floor level of the nave. This rope allows visitors to swing over the entire nave and their pendular motion influences the solar equations above: if no one participates the Sun is quiet and calm, as there is movement the projections get more turbulent and the Sun begings to rotate along its vertical axis. The shadow of participants is projected onto the apse of the church and a second tracking system automatically generates smoke which is mapped onto the architecture in such a way that it accumulates on the ceiling of the apse.
The installation is inspired by the Christian Botafumeiro, the Foucault pendulum demonstrating the rotation of the earth, or the form of torture and execution of the Inquisition that Edgar Allan Poe described in his 1842 story “The Pit and the Pendulum”. Nave Solar is designed to evoke the myth of Icarus, the TV games of Luis Manuel Pelayo, and the synchronization of pendulum clocks that Huygens discovered in 1665.
