On 2014, December 14: appointment for a lecture on Energy in Art by Andrea Amato, scholar of Energetic Building Biology, Biocompatibility and Environment Harmonization. With reference to the work n. 315, the lecturer dicusses about space and time and how a work can influence the environment's energy and the observer's emotion. The awareness of the space depends on the consciousness of the observer or is it something quite clear a priori? Can the time occupy a space inside the work? In a work past and future coexist in a timeless present; the artist is able to stop time for ever and the public, observing the work, can leave in the work something of himself.
