This article aims to analyse the functions of the apocalyptic model in Les Écailles du ciel (1986) by Tierno Monénembo. Representing first a system of intelligibility for the characters to make sense of the events, the apocalypse serves also, on the level of narration, to structure the disastrous history of colonial and dictatorial Guinea. The construction of complex temporalities allows for going beyond teleology and nuancing the impact of the narrated events. Finally, a post-apocalyptic narrative emerges, told by a narrative voice situated after the « end of times ». This voice cannot be considered as the voice of an individual subject, insofar as it seems to be the repository of everything that needs to be told after the destruction of the world. I will therefore suggest thinking of this voice as belonging to a post-apocalyptic subjectivity who reinvents the function of the traditional griot, singularly modifying its contours.
