The fondazione merz is preparing to celebrate its fourth anniversary by publishing i quaderni, a series of slender books aiming to inform the public of all the activities promoted by the Torinese institution. Each issue will be based upon an event of particular importance – to be documented with images in a manner that is better and more comprehensive than the eventual catalogue – and so recreate the entire season of which it is a part, recording the gossamer threads the things of art follow. Threads that echo an interrupted dialogue with Mario Merz, with his works that are preserved and presented by the fondazione, and with his writings, an unpublished selection of which will be presented in each issue of i quaderni. Every quaderno will be rounded off with a section of Technical notes, with the lists of works exhibited, and a Chronology presenting, in synoptic tables, the complex itinerary packed with performances, readings, didactic activities, congresses, planned by the scientific committee which, alongside its president, Beatrice Merz, comprises Richard Flood (The New Museum, New York), Dieter Schwarz (Kunstmuseum, Winthertur) and Vicente Todolí (Tate Modern, London). This first quaderno is dedicated to Sol LeWitt, the most important representative of Minimal art in Europe and America.
