Étienne-Jules Marey's chronophotographic gun
This is the photo of Étienne-Jules Marey's chronophotographic gun, now at the Musée des Arts et Métiers (Paris). With this instrument the French scientist was capable of taking 12 consecutive frames a second, all on the same picture, which gave him the possibility to study animals' behavior. Marey started his photographic experiments from Villa Maria, in Naples, where he was named "the mad man of Posillipo", as Neapolitan people always saw him gazing at birds with satisfaction, without shooting them.
