The globalized world is characterized by an erectile tendency that leads to an increasing disproportion between different cultures. Such a disproportion is synonymous with a peril for some cultures. In order to avoid the disparity of local cultures, some writers are referring to the novel as a media of oral traditions. It is the case for Fatou Diome with the works Le Ventre de l'Atlantique and Impossible de grandir. The two novels clearly appear as the memories of Serere traditions in Senegal. Thus, it seems accurate to read this corpus to the purpose to testify a literary approach to patrimonialization. The study is directly connected with the question of oral traditions backup by the means of the novel. The links between scripturality and traditional speech betray the characteristic of the novel writing as a media serving oral traditions. Consequently, the analysis is giving an interest to media interactions between novel and oral genres. This intermediality is underlined through an intertextual reading of the corpus. Therefore, the study is based on the hypothesis stipulating that the texts in the corpus are manifestations of a "secondary orality" that allows the protection and the diffusion of endogenous heritage.
