From the early 1960s, he explored art-making from a conceptual point of view, asserting himself as an independent figure both with respect to the militant art that characterized the 1968 movement in Italy and with respect to the Arte Povera group, despite participating in some of their events at the invitation of G. Celant.
Since his first showing in a collective exhibition in 1961, and his first personal exhibition in 1964, he has held countless exhibitions in galleries and museums all over the world. His work has been featured in numerous international public collections.
A trained graphic designer, he has always shown a particular interest in the editorial field and the written word. From the outset, he has accompanied his artistic research with reflections collected in books he edited himself, from Idem, published in 1975 by Einaudi (Turin) with an introduction by Italo Calvino, to Quattro Passi. Nel Museo Senza Muse published in 2006 by the same publisher, and L’autore che Credeva di Esistere, published by Johan & Levi (Milan) in 2012. From 1969, he also created sets and costumes for theatrical performances, including projects conceived with Carlo Quartucci in the 1980s and the recent scenography sets for two works by Richard Wagner directed by Federico Tiezzi (2005, 2007).
