A label discussed and often rejected, decadentism nevertheless manifests an interpretative effectiveness that is still relevant. The passage from the nineteenth century to the twentieth century is at stake: for the literature of our country, in fact, the entry into the twentieth century has led to radical changes, particularly in the field of poetry, is very visible and marked the discontinuity with the previous century. Decadentism is a moment of transition between two different practices of literature: the expression of the crisis of nineteenth century values, but not yet true twentieth century. The volume provides a concise but comprehensive picture of this "ism" without forgetting its main figures: Gabriele D'Annunzio and Giovanni Pascoli, but also Antonio Fogazzaro and Gian Pietro Lucini. And, of course, father of all: Giosue Carducci.
