Mary Shelley determined to write his biography. In a letter of 17 November 1822, she announced: "I shall write his life—& thus occupy myself in the only manner from which I can derive consolation." However, her father-in-law, Sir Timothy Shelley, effectively banned her from doing so.Sir Timothy Shelley made his allowance to Mary (on behalf of Percy Florence) dependent on her not putting the Shelley name in print. Mary began her fostering of Percy's poetic reputation in 1824 with the publication of his Posthumous Poems. In 1839, while she was working on the Lives, she prepared a new edition of his poetry, which became, in the words of literary scholar Susan J. Wolfson, "the canonizing event" in the history of her husband's reputation. The following year, Mary Shelley edited a volume of her husband's essays, letters, translations, and fragments, and throughout the 1830s, she introduced his poetry to a wider audience by publishing assorted works in the annual The Keepsake. Evading Sir Timothy's ban on a biography, Mary Shelley often included in these editions her own annotations and reflections on her husband's life and work. "I am to justify his ways," she had declared in 1824; "I am to make him beloved to all posterity." It was this goal, argues Blumberg, that led her to present Percy's work to the public in the "most popular form possible". To tailor his works for a Victorian audience, she cast Percy Shelley as a lyrical rather than a political poet. As Mary Favret writes, "the disembodied Percy identifies the spirit of poetry itself". Mary glossed Percy's political radicalism as a form of sentimentalism, arguing that his republicanism arose from sympathy for those who were suffering. She inserted romantic anecdotes of his benevolence, domesticity, and love of the natural world. Portraying herself as Percy's "practical muse", she also noted how she had suggested revisions as he wrote. Despite the emotions stirred by this task, Mary Shelley arguably proved herself in many respects a professional and scholarly editor. Working from Percy's messy, sometimes indecipherable, notebooks, she attempted to form a chronology for his writings, and she included poems, such as Epipsychidion, addressed to Emilia Viviani, which she would rather have left out. She was forced, however, into several compromises, and, as Blumberg notes, "modern critics have found fault with the edition and claim variously that she miscopied, misinterpreted, purposely obscured, and attempted to turn the
