Wandering in this labyrinth of public and historical spaces is fascinating because of the powerful sensory impressions that are literally presented to us: the powerful Mediterranean light with its numerous nuances, which Caravaggio once masterfully captured. The generous, even lush public spaces like the gigantic volume inside the Pantheon, embraced by two thousand year old walls. The variety of smells and noises that flow towards us between park landscapes, car lanes, bars and church interiors. The surfaces of stones touched by thousands of pilgrims and worn down marble steps. The travertine facades of the palazzi and churches, which, like a canvas, subtly reflect the colors of the surroundings and the deep blue sky.
