“With photography I have the means to expand the language in order to include the gestures and the figure of the author in the investigation...The blue ink sign flows beyond here, over the photograph of the painter at work, who is therefore an actor, not the author of the image that we observe. ”—Giulio Paolini
Together with the use of photography, the introduction of the figure of the author and of his relationship with the work constitutes, for Paolini, the main theme of reflection around the mid-1960s.
