Mary Shelley
She began writing what she assumed would be a short story. With Percy Shelley's encouragement, she expanded this tale into her first novel, Frankenstein: or, The Modern Prometheus, published in 1818. She later described that summer in Switzerland as the moment "when I first stepped out from childhood into life". The story has been fictionalised several times and formed the basis for a number of films. In September 2011 the astronomer Donald Olson, after a visit to the Lake Geneva villa the previous year, and inspecting data about the motion of the moon and stars, concluded that her waking dream took place "between 2am and 3am" 16 June 1816, several days after the initial idea by Lord Byron that they each write a ghost story. Authorship of Frankenstein Since Frankenstein was published anonymously in 1818, readers and critics argued over its origins and the contributions of the two Shelleys to the book. There are differences in the 1818, 1823, and 1831 editions, and Mary Shelley wrote, "I certainly did not owe the suggestion of one incident, nor scarcely of one train of feeling, to my husband, and yet but for his incitement, it would never have taken the form in which it was presented to the world." She wrote that the preface to the first edition was Percy's work "as far as I can recollect." James Rieger concluded Percy's "assistance at every point in the book's manufacture was so extensive that one hardly knows whether to regard him as editor or minor collaborator" while Anne K. Mellor later argued Percy only "made many technical corrections and several times clarified the narrative and thematic continuity of the text." Bath and Marlow On their return to England in September, Mary and Percy moved—with Claire Clairmont, who took lodgings nearby—to Bath, where they hoped to keep Claire’s pregnancy secret. At Cologny, Mary Godwin had received two letters from her half-sister, Fanny Imlay, who alluded to her "unhappy life"; on 9 October, Fanny wrote an "alarming letter" from Bristol that sent Percy Shelley racing off to search for her, without success. On the morning of 10 October, Fanny Imlay was found dead in a room at a Swansea inn, along with a suicide note and a laudanum bottle. On 10 December, Percy Shelley's wife, Harriet, was discovered drowned in the Serpentine, a lake in Hyde Park, London. Both suicides were hushed up. Harriet’s family obstructed Percy Shelley's efforts—fully supported by Mary Godwin—to assume custody of his two children by Harriet. His lawyers advised him to improve his case by marrying; so he and Mary, who was pregnant again, married on 30 December 1816 at St Mildred's Church, Bread Street, London. Mr and Mrs Godwin were present and the marriage ended the family rift. Claire Clairmont gave birth to a baby girl on 13 January, at first called Alba, later Allegra. [note 7] In March of that year, the Chancery Court ruled Percy Shelley morally unfit to assume custody of his children and later placed them with a clergyman's family. Also in March, the Shelleys moved with Claire and Alba to Albion House at Marlow, Buckinghamshire, a large, damp building on the river Thames. There Mary Shelley gave birth to her third child, Clara, on 2 September. At Marlow, they entertained their new friends Marianne and Leigh Hunt, worked hard at their writing, and often discussed politics. At Marlow, Mary edited the joint journal of the group's 1814 Continental journey, adding material written in Switzerland in 1816, along with Percy's poem "Mont Blanc". The result was the History of a Six Weeks' Tour, published in November 1817. That autumn, Percy Shelley often lived away from home in London to evade creditors. The threat of a debtor's prison, combined with their ill health and fears of losing custody of their children, contributed to the couple's decision to leave England for Italy on 12 March 1818, taking Claire Clairmont and Alba with them. They had no intention of returning. Italy William "Willmouse" Shelley, painted just before his death from malaria in 1819 (portrait by Amelia Curran, 1819) One of the party's first tasks on arriving in Italy was to hand Alba over to Byron, who was living in Venice. He had agreed to raise her so long as Claire had nothing more to do with her. The Shelleys then embarked on a roving existence, never settling in any one place for long. [note 8] Along the way, they accumulated a circle of friends and acquaintances who often moved with them. The couple devoted their time to writing, reading, learning, sightseeing, and socialising. The Italian adventure was, however, blighted for Mary Shelley by the deaths of both her children—Clara, in September 1818 in Venice, and William, in June 1819 in Rome. [note 9] These losses left her in a deep depression that isolated her from Percy Shelley, who wrote in his notebook: My dearest Mary, wherefore hast thou gone, And left me in this dreary world alone? Thy form is here indeed—a lovely one— But thou art fled, gone down a dreary road T
