It’s well-known how the work of Medardo Rosso (Turin 1858 – Milan 1928) is considered “unstable”, the result of the spatio-temporal vibrations that distinguish its impressive but uncertain presence. The artist used to photograph his sculptures, their installation and position in space, putting a final “seal” on the whole with a further photograph of the whole sequence, thus stressing that the photograph itself was very much part of his poetic. In studying the research and aims of Rosso, Angelo Garoglio reveals his vision to us, presenting images of the great master’s works to the public. In particular, it will be possible to admire the shots of Madame X, a masterpiece the sculptor himself considered his “favourite daughter”, donated with seven others to Ca’ Pesaro in 1914 during the XIth Venice Biennale.
