The aim of the research is to pay homage to two artists, such as the Italian photographer Luigi Ghirri and the French illustrator Jean Giraud, aka Moebius, a master of science fiction. Considering that the two artists examined may seem apparently not very similar, both in terms of poetics and in terms of the final results of their work, this essay seeks to demonstrate the existence of a common thread that links two worlds, two experiences, two different interpretations of art, two careful looks to scrutinize what is, to imagine what is not there.
