Abstract: One of the most mysterious aristonyms of the nineteenth century is that of Isidore Ducasse. But the count of Lautréamont is not his only pseudonym because the hero that he dramatises, Maldoror, identifies himself with another character: that of the author himself. The œuvre suggests more or less implicit links between the fiction and biography of Isidore Ducasse. In Ducassian poetics, the signature seems to ratify the creation of a fictive identity, both literary and fictional.
