Spiritual, mystic and natural boundaries haunt the writings of Henri Bosco. Critics such as Bachelard have studied Bosco's interpretation of the natural elements and noted his sensitive portrayal of the protagonists with a focus on their unconscious desires by the use of this device. In Le Mas Theotime Bosco has unleashed his artistic and poetic creativity in addition to his passion for nature. Indeed, of all of Bosco's novels, perhaps this one exemplifies the quintessential harmony of man with nature. As suggested by Jean-Claude Godin: " ... il n'y a que dans Le Mas Theotime oil elles soient veritablement au coeur du recit ... La reverie de la terre debouche alors sur toutes les images de l'intimite heureuse." (Godin 176) It is also the essence of Provence, its legends and its natural beauty that plays an integral role in this novel. Not only does Bosco explore the natural elements, but he also explores the religious myths that so influence our society. This thesis will explore, through a symbolic and religious interpretation, the boundaries which prevail throughout. Le Mas Theotime incorporates Bosco's true genius as a writer who brings to his reader the possibility of a personal rendition and view of the story. His is not a straightforward and evident recollection of events, but rather a voyage through and involvement in the lives and minds of the characters.
