Although one might sink into this concert of sensory impressions, an essential component of the Rome experience is added: The countless historical stimuli that arouse curiosity and spiritual stimulation in us. These are not only the physical evidence like the buildings themselves, but also the continuity between them in the processing of the past. The multiply reused spolia and reused components refer to lost works from bygone eras. In other places they come to light directly through the excavation work carried out since the Enlightenment. The architectural and formal processing of classical buildings by the artists of the Renaissance also contributes to this continuity in perception. The borders of the Roman epochs merge into a lasting total work of art.
