Partant du constat de l'omniprésence de Lucien dans son corpus, notre thèse se propose de dresser un panorama des autoreprésentations auctoriales dans l'ensemble de l'œuvre de Lucien de Samosate, mais dans une perspective résolument théorique. En effet, parce qu'il se constitue comme point focal de sa propre œuvre, Lucien a souvent tendance à faire l'objet d'une lecture biographique de la part de la critique. Cette thèse se donne pour objet de redonner à l'autoreprésentation de l'auteur son sens de geste poétique. En choisissant le terme de figure, auquel on donne ici un sens plus restreint qu'à celui de persona, on s'intéressera uniquement aux moments où l'auteur fait explicitement l'objet de son propre discours.La première partie de notre thèse consiste donc en une importante typologie des mises en scène de soi chez Lucien: on part des apparitions les plus explicites de l'auteur en contexte référentiel, dans le corpus oratoire ou biographique, pour traiter ensuite de la partie fictionnelle du corpus. L'un des objectifs de ce travail est en effet de redonner à Lucien sa place de pionnier dans l'invention de l'autofiction.La seconde partie de notre thèse tire les conclusions poétiques de cette typologie, en dégageant aux autoreprésentations de l'auteur une double fonction : d'abord, elles doivent dire l'individu social et intellectuel, mais dans une démarche qui transcende les genres et la séparation traditionnelle entre référentialité et fiction. Ensuite, les figures de l'auteur ont pour fonction de servir de vecteur à un message métapoétique extrêmement riche, qui va de la théorie de la fiction à celle de la réception. / The starting point of this PhD thesis was the constatation of Lucian's omnipresence within his own corpus. This phenomenon often led critics to have an excessively biographical approach to this author. The aim of this thesis is thus to give an account of the vast scope of self-representations within Lucian's corpus, in a theoretical perspective, in order to show that the staging of the self can be seen as a poetical gesture. The first part of this work thus consists in a typology of all the auctorial self-representations that can be found within Lucian's œuvre. It ranges from the most explicit forms of authorial presence, in referential works, such as prolaliai and biographies, to the most fictional part of the corpus. The aim of this work is to establish Lucian's position as a pioneer in the invention of autofiction.The second part of this thesis draws the theoretical conclusions of this typology, by showing that authorial self-representations have two main functions : first, they help defining Lucian's social and intellectual identity, beyond generic boudaries ; second, they serve a metaliterary purpose : as vicarious surrogates, Lucian's doubles appear as a powerful means of expressing his aesthetical views.

The work confronts prosaic pieces with noticeable autobiographical features. It deals namely with works of Edgar Dutka, Eliška Vlasáková and Antonín Bajaja. It was not a coincidence to choose right these three Czech authors. They have quite a few features in common. They all belong to the same generation. They are born in the 40's of the 20th century, so they have spent an essential part of their lives (childhood, adolescence and substantial part of their working age) in the second half of the 20th century - in the time of political convulsions and social changes. A childhood spent during this period has become their common literary theme. They all make their memories a literary piece. Each of them does it in a different way and with a different amount of accuracy. Their inspiration comes from their real life, from their memories. The next common feature of these three authors is that they all wrote some of their texts without a vision to make them public. They wrote them for themselves. Book editions were carried out after the year 2000. Last but not least mutual fact is that all of these three authors have been nominated for a prestigious literary price. Edgar Dutka's works show the interdigitation of fictional worlds and also the diffusion of these worlds in the real life of the author. Eliška...
