Sulphurea, developed during an artist's residency in Rapolano Terme (SI), investigates how the territory of the province of Siena is continuously shaped by the geothermal activity of the subsoil, which manifests itself through the presence of sulphurous waters. \Men experiences it continuously through their body and senses: by isolating the context and details that reveal its source, Sulphurea recreates a microcosm, a world within the world, from which to start again for a more conscious reading of the territory.
