The exhibition "(RE)VERSVS. Reuse and Redemption in the Patrimony of the Vatican Library and in the Art of Sidival Fila" is the result of a profound reflection by the artist and the curators of the Vatican Library on the theme of reuse - redemption, conceived as two different, and at times opposing, possibilities of using and valorising an ancient, or simply previous or extraneous, material in a new and different way. It presents a recovery of fragments and discards of manuscripts, textiles, marbles and other materials that, in the case of reuse, defines their new purpose, while in the case of redemption celebrates them in themselves, in their ontological value, regardless of their possible new utility. The exhibition concludes in the Sala Barberini with the site-specific installation 'Natura Artificialis', a work that represents the Brazilian artist's integral vision, the starting point of his critical view of the human race and the erroneous idea of nature seen solely as being at the service of man.
