Of all the novels and stories which Mary Wollstonecraft Shelley left in manuscript, only one novelette, Mathilda, is complete. It exists in both rough draft and final copy. In this story, as in all Mary Shelley's writing, there is much that is autobiographical: it would be hard to find a more self-revealing work. For an understanding of Mary's character, especially as she saw herself, and of her attitude toward Shelley and toward Godwin in 1819, this tale is an important document. Although the main narrative, that of the father's incestuous love for his daughter, his suicide, and Mathilda's consequent withdrawal from society to a lonely heath, is not in any real sense autobiographical, many elements in it are drawn from reality. The three main characters are clearly Mary herself, Godwin, and Shelley, and their relations can easily be reassorted to correspond with actuality.
