From Hegel to Heidegger and Agamben, modern Western philosophy has been haunted by how to think the connections between death, humanness and animality. This article explores how these connections have been represented by Italian writers Tommaso Landolfi (1908–79) and Stefano D'Arrigo (1919–92). Specifically, it investigates how the death of a nonhuman animal is portrayed in two works: ‘Mani’, a short story by Landolfi collected in his first book Il dialogo dei massimi sistemi (Dialogue on the Greater Harmonies) (1937), and D'Arrigo's massive novel Horcynus Orca (Horcynus Orca) (1975). Both ‘Mani’ and Horcynus Orca display how the fictional representation of the death of a nonhuman animal challenges any philosophical positions of human superiority and establishes instead animality as the unheimlich mirror of the human condition. In fact, in both stories, the animal — a mouse and a killer whale, respectively — do die and their deaths represent a mise en abyme that both arrests the human narrative and sparks a moment of acute ontological recognition.
