Michelangelo Pistoletto picks up this dare and shows us six "dining tables of cultures", projected thinking at the form of the seas that link different people, landscapes and cultures: from Mediterranean sea to Baltic, from South China sea to Caribbean sea, without forgetting Black and Red sea. If a sea joins, an island can be the setting of a world in which art claims a responsible change in society: in San Servolo island near Venice, the italian artist presented Cittadellarte, some installations that show a different social structure in politics, communication, works, economics and so on. Even the book's construction reflects Pistoletto's sensibility towards nature: every page, included cover, are made of aluminium. Some of these are punched and, like open doors, show the concepts on which is based the new civilization pushed by Cittadellarte.
