26/8/18. Invented in 1788, the panorama reached the height of its popularity at the time of the 1900 Universal Exhibition. Vast circular canvases installed in purpose-built rotundas were designed to be viewed from centrally placed platforms and attracted an admiring public. The aim was to produce a perfect illusion. Thus the relationship between viewer and 'reality' underwent a profound mutation, opening up a new logic according to which the world was transformed into a spectacle and images substituted for direct experience.
