Query: The Great Shadow - A Fiction Lived, a Life Ficcioned

The Great Shadow is one of the novels of the only Sa-Carneiro's book dedication to Fiction. But is is central in the identification of the key-structure that allows that his works talk about his life, and vice-versa. No one, has constructed as Sá-Carneiro did, a romantical project that would make his life the total fulfillment of his poetical project. And The Great Shadow brings us the fantasmagorical story of a man pursuited by his shadow, appealing, stressing and killing his own reflection of himself; his shadow is himself, because the Other is the only condition he has to live and see himself. This obsession with the Other will lead him to death by suicide. As in the book: in a profound despair, the protagonist kills himself and his shadow, as a way to finish his life of agony and self-division. A book that situates us in the drama of the Portuguese First Modernism, by the hand of our most desgraceful and auto-biographical poet.
