The purpose of this paper is to present several avenues of reflection linked first to the onomastics of the African episcopate of the Byzantine period, then to its development. A quick overview of the most typical characteristics of onomastics of this period will be presented, followed by a description of the remarkable development of this African episcopate between the sixth and the beginning of the eighth century. It will conclude with observations on the African onomastic repertoire of the Protobyzantine era, which reflects the evolution of mentalities within the very interior of the African Christian people and the different circles within it.
