The first five issues of DIVISARE BOOKS are dedicated to an important and unpublished series of drawings of Italian architect Dario Passi (1939), a key player in the ‘Tendenza’, the Italian architectural movement of the sixties, seventies and eighties which re-introduced the symbolic signs of history into contemporary creation. Echoing the architectural research of Aldo Rossi and Giorgio Grassi on the one hand and the work of artists such as Enzo Cucchi or Francesco Clemente on the other, Passi’s architectural research still awaits to be studied and fully acknowledged by the architectural criticism. The drawings collected in these publication bear witness to his architectural research throughout the first half of the 80’s, a decade during which Passi worked to his last architectural projects such as the urban development for the Lungotevere Flaminio in Rome (published on DIVISARE BOOKS #33), the design competitions for the Opéra La Bastille in Paris and the Lützowplatz in Berlin as well as his participation to the 4th International Architecture Biennale in Venice directed in 1986 by Aldo Rossi.
