Renato Barilli opens the course by introducing his theory on the relationship between art and contemporary technologies, emphasizing how the revolutions in artistic languages from the late 19th to early 20th century are intrinsically linked to technological innovations. Referring to the evolution of electrical and electromagnetic technologies, the instructor shows parallels with the works of artists such as Paul Cézanne, Georges Seurat, and Paul Gauguin, who were the first to manifest opposition to visual mimicry and a different conception of space: no longer linear and perspectival, but synthetic, tactile, and immersive.
