Like Humanism, a literary movement of European thought during the Renaissance which is characterized by a return to ancient texts as a model of life, writing and thought (1304-1374), Otwere is also interested in teaching Embosi language, mbosi literature and culture. In his past considered as traditional literature, the institution Otwere entered the annals of written literature after the negritude, movement created in the late 1930s that brings together French-speaking African and African writers to highlight African cultures. According to several sources, the first form of French-speaking African literature appeared in 1920. Otwere, despite its presence in the Mbosi milieu since pre-colonial times, only officially became known as literature in the 1970s when Congolese researchers give special attention. In this work we will present the metamorphoses of Otwere, its stages of transformation, that is to say, from its traditional oral form to today's so-called modern or written.
