My article's intention is to draw a path through the pages of Discourse of an Italian concerning romantic poetry questioning the text on the matters of Ferine and Divine, like the ones that emerge from the particular Leopardi's reading of Xenophanes' fragment about Gods in bovine and horse-like forms. The desire of the presence of Similarity that Leopardi gets from Xenophanes establish the creating mechanism and the anthropological foundations of Greek fables. Ferine and Divine are referent of the desire of Similarity and, therefore, they represent the prerogatives of defense of ancient fables as illusion of imagination. Some anthropomorphous figures of Small Moral Works , in particular the Imp and the Gnome represent the literary outcome of the interpretation of Xenophanes' fragment made by Leopardi on the pages of Discourse .
