This article aims to offer some observations on Fabio Pusterla's most recent collection, Fiumi, nefrite, vortici (2025), focusing on his relationship with two important figures, Vasily Grossman (author of the novel Stalingrad) and, above all, Arthur Rimbaud. In particular, it highlights certain traces of unconscious material that resurface mainly in two texts, Le acque sotterranee and Ultimo fiume. The analysis focuses on the presence of the aquatic element and the symbol of the river, which has been central to Pusterla's work since at least his collection Cenere, o terra (2018). Finally, another Rimbaud — that of L’Éternité — also reappears in the last poem of Fiumi, nefrite, vortici.
