Three days organised in 5 working sessions and an internal meeting to encourage a scientific and political debate in the presence (physical and virtual) of Ambassadors, Authorities, Researchers and Journalists, all hosted in the wonderful gallery frescoed by Pietro da Cortona of Palazzo Antici Mattei, seat of the Centre for American Studies, in whose rooms the poet Giacomo Leopardi lived for a few weeks from November 1822, staying in these rooms until April 1823, as a guest of his maternal uncle, Carlo Antici. Rooms that two centuries later have also inspired the REACT researchers.
