«In order to study and promote this shared Dutch, Portuguese and Florentine cultural heritage, which can only be understood, reevaluated and appreciated by adopting a multicultural and multimedia approach, we created a consortium that brought together the Biblioteca Medicea Laurenziana, the NIKI-Nederlands lnteruniversitair Kunsthis­torisch Instituut, the University of Groningen, the CHAM-Centro de Humanidades della Faculdade de Ciencias Sociais e Humanas at the Universidade Nova de Lisboa (NOVA\FCSH), the Accademia della Crusca, the Centro lnteruniversitario di Studi di Storia Globale GLOBHIS (Universita di Firenze, Trieste, Piemonte Orientale e Tuscia), the Polo Museale della Toscana and the Archivio di Sta to di Firenze. The synergies and complementary knowledge and expertise offered by these cultural institutions in Ita­ly, the Netherlands and Portugal made it possible to organize the exhibition, the cata­logue, the digital repository and the international conference. Starting with the study and reevaluation of the Carte di Castello, these integrated initiatives are exploring and researching the complex dynamics of the connected world of the mid-nth century, with particular emphasis on the history of cultural, financial and political relations between Tuscany, the Netherlands and Portugal.»
