Forse che sì forse che no (Maybe Yes, Maybe No) is a novel published in 1910 by Gabriele D'Annunzio. As all D'Annunzio's novels, Forse che sì forse che no echoes to a certain extent one of D'Annunzio's own experiences. In particular, this novel echoes D'Annunzio's summer of "erotic frenzy with Donatella [Cross]." D'Annunzio originally planned to title the novel Vertigine. He later attempted to change even Forse che sì forse che no, because they made him notice that the rhythm matched the Neapolitan popular song Funiculì, Funiculà. It is considered the "last great D'Annunzian novel." Source: Wikipedia (en)
