Our book contains three studies of different French-language works, each with a distinct literary and linguistic perspective:Le Repos du septième jour: a Catholic drama through which the author had wanted to emphasize the necessity of introducing the divine work into our lives. The eschatological aspect of this work is enriched by a wealth of religious and literary resources, making it unique. Antoine de St. Exupéry's The Little Prince: where the humanism and philosophy uncovered leave no doubt that the tale is intended for readers of all ages. Based on this assumption, we will analyze the various aspects that make such a universal work a masterpiece for children and adults alike.The Franco-Egyptian autobiographical experience, in two works by Ahmad Rassim which are selected poems from his collection Le livre de Nysane and also from his diary entitled Le journal d'un pauvre fonctionnaire, is a phenomenon that escapes the theoretical straitjacket even after the Lejeunienne definition that would later shine through in the 1970s, marking the beginning of a literary controversy.
