This analysis shows that Reinaldo Arenas' work is one of exile and alienation. Arenas, as a human being as well as an author, suffered all forms of exile, and these influence the structure of his work. In his literary work, as well as in his life, all the definitions of exile given by sociology are present; that of inner exile, to which Arenas added a new characteristic, and that of territorial exile as well. His work represents the vision of the marginated, imprisoned, persecuted, rejected. The purpose of his novels and poetry is to reveal, from a historical reconstruction, the explanation of Cuba's constant political problems.
