Abstract: From the “disturbing” discovery of a sacrificial poetics marked by melancholy, Bonnefoy was nourished by Nervalian experiences, lived, dreamed, written in verse as in prose, in Paris, in Valois or in Italy, welcoming the lucidity of the poet as a salutary source of influence for an ethical practice of poetry, putting the dream in Sylvie in correspondence with her experience of Elsewhere and Here, drawing on it, beyond the gnosis, the hope of presence as the very act of poetry.
