In the month of March 2006 the workshop Conservation and Cleaning of Marble Sculptures was held at the Lina Bo and P.M. Bardi Institute, in partnership with the Círculo dos Antiquários de São Paulo [Antique Dealers Circle of São Paulo]. Fifteen professionals in the field of conservation and restoration of art objects were able to brush up on their knowledge and learn new techniques, enabling them to execute future work in marble conservation in Brazil. During the workshop, work was carried out on the cleaning and conservation of the Roman statue Diana the Hunter, an artwork dating from 1 A.D., belonging to the collection of the Lina Bo and P.M. Bardi Institute. The workshop was taught by Prof. Dr. Piero Frizzi, who teaches at Palazzo de Spinelli, in Florence, Italy.
