Abstract: « Oh ! Questa vita sterile, di sogno! » is one of the most famous verse of a Guido Gozzano’s poem. It expresses the reaction of the Crepuscolarismo movement against Symbolism. This reaction is founded on an imaginary that I have tried to explain thorough the work of Vittorio Pica, critic and essayist who have diffused the Symbolist and Decadent movement in Italy.
