This chapter reconstructs Gabriele D’Annunzio’s ethnonationalist mythography of Italian rebirth, arguing that it centers on a sustained metaphor of ‘Renaissance’ that unifies disparate elements of his thought into a coherent symbolic system, made widely recognizable through repetition, intertextuality, and the ritualization of cultural memory. The first section examines how D’Annunzio integrated the cult of expectation into a nationalist, para-religious vision that extended the patriotic narratives of the Risorgimento and built upon the Renaissance legacy. The second section discusses how D’Annunzio fashioned himself as a transhistorical mediator who bridged tradition and modern renewal, focusing on how his writings conceptualize landscapes, artworks, and memory as palimpsests of Italian greatness. Placed in dialogue with Roger Griffin’s notion of epiphanic modernism, D’Annunzio’s visionary aesthetic became a vehicle for recovering a transcendent national essence. Finally, the chapter examines D’Annunzio’s self-representation as the perfect humanist in Il libro segreto (1935), which reflects his lifelong politicization of Renaissance humanism.
