Expo Milano 2015. Hundred large format photographs of a great photographer to grasp the nuances of this unrepeatable and unique image of our present time. Those who visited the Expo will relive the atmosphere all over again. Those who were not there will enjoy this late visit. Both will be able to better understand what they have absorbed through the huge media coverage of the event, stripped of clichés thanks to Nigel Sato's outsider' view.

A sequence of images whose common thread is the memory of the human species, the memory we carry within us, and which, when prompted to surface in consciousness, gives rise to associations—sometimes very remote, as remote as the history of intelligence, sometimes recent, relating to contemporary cultural institutions. Thus, fossils of memory, like viruses hydrated by the encounter with something capable of nourishing them, come back to life and become fully effective.
