Since 1997, each year the artists of the Corso Superiore di Arte Visiva of the Fondazione Antonio Ratti in Como have presented their most recent works, created following the experience of the course held the previous summer. The course, under the artistic direction of Annie Ratti and curated by Giacinto di Pietrantonio and Angela Vettese, is coordinated by Anna Daneri.

Eight months after the ninth edition, led by the artist Richard Nonas, Tracce di un seminario aims to explore, through an exhibition, the artistic development process of each student: Roberto Ago (Italy), Daniele Bacci (Italy), Melania Bugiani (Italy), Beatrice Catanzaro (Italy), Simone Cesarini (Italy), Nemanja Cvijanovi (Croatia), Maria Adele Del Vecchio (Italy), Elenia De Pedro (Italy), Gian Carlo Floridi (Italy), Alice Guareschi (Italy), Jin Ha (Korea), Giovanni Kronenberg (Italy/Switzerland), Alessandra Lopes Caffarena (Brazil), Renee Lotenero (USA), Marco Magni (Italy/Germany), Marianna Mandirola (Italy), Andrea Melloni (Italy), Renato Jaime Moranti (Italy/Spain), Alek O. (Argentina), Youbi Tchonang (Cameroon), Joaquin Peña-Toro (Spain), Dragana Sapanjo (Croatia), Alberto Trapani (Italy), Nikola Uzunovski (Macedonia), Kate Vickers (Australia).

At the venues of Careof and Viafarini, the network of experiences and creativity shared during the course is reconstituted, and the individual paths of each of the twenty-five participants emerge. A common thread is the particular focus on the relationship between art and space, a theme strongly present in the work of Richard Nonas.

On the occasion of the exhibition, a book dedicated to Richard Nonas's course will be presented, published by Charta in the series Quaderni del Corso Superiore di Arte Visiva.

Among previously published volumes, dedicated to past visiting professors: Joseph Kosuth (1996), John Armleder (1997), Allan Kaprow (1998), Hamish Fulton (1999), Haim Steinbach (2000), Ilya Kabakov (2001), Marina Abramović (2002), Giulio Paolini (2003).
