Considered as an archetype, the child is a human constant, presented in different ways across time and cultures. By referring to the hidden child beneath him, to this "myth of interiority", Richard Millet attempts to rebuild his inner being through gathered and coordinated mythographies, in order to clearly illuminate the dark truth of the first years of life and those following the loss of the childhood. The purpose of our work is to clarify the paths of this quest of the childhood using first the symbolic places and time, Corrèze and Lebanon are the privileged places of the author’s childhood and his characters, flickering between the past or the first age and the present of the adult. Second, the myth of the childhood is interpreted through the imagination and the recurrent mythical figures : the image of the child in the Bible and the Christian tradition, the image of both the family and the infernal dark abyss where the child fell apart after the loss if his childhood. Finally, the images of death demonstrated in all the different forms of loss, haunt the milleten child, not only the fictional character but also the writer. So this is a game between autobiography and the fiction in writing. The birth of a milleten myth is supposed to appear through the creation of some iconic characters like Pascal Bugeaud, fictional reflection of the author, and through the internal intertextuality between the works. Therefore, the childhood of Richard Millet is involved in the contemporary literature in a romantic way, showing the perpetual conflict between the childhood, the man and the outside world.
