The work is based on the mimetic reproduction in resin and fiberglass of a stone found in a publicspace, whose origin is unknown. The material this replica is made of is very light, but the way it isoil painted suggests the weight and robustness of a real stone. It remains suspended above thepublic, in an absurd presence in the manner of Magritte, which lifts us into a waking dream, at a timewhen truths are imposed on us - belief as a paradigm - with the creation of alternative facts or truefictions, which act in language, in communication, and which drastically influence contemporarylife. In this context, the title is a key element, since from this false truth, it suggests a belief or ideathat cannot be questioned or changed, that cannot be changed, that cannot be rationalized, animmutable truth, like a stone that (apparently) cannot be moved or even touched.
