Hope Mirrlees (8 April 1887–1 August 1978) was a British translator, poet and novelist. She is best known for the 1926 Lud-in-the-Mist, a fantasy novel and influential classic,  and for Paris: A Poem, a modernist poem that critic Julia Briggs deemed "modernism's lost masterpiece, a work of extraordinary energy and intensity, scope and ambition."
Born in Chislehurst, Kent and raised in Scotland and South Africa, Mirrlees attended the Royal Academy of Dramatic Art before going up to Newnham College, Cambridge to study Greek. While at Cambridge, Mirrlees developed a close relationship with famous classicist Jane Ellen Harrison, Mirrlees' tutor and later her friend and collaborator.
Mirrlees and Harrison lived together from 1913 until the elder's death in 1928.  Although they divided their time mainly between the United Kingdom and France, often returning to Paris to continue Harrison's medical treatments, their travels also took them to other European countries. Both of them studied Russian, Mirrlees earning a Diploma in Russian from the École des Langues Orientales of Paris, and went on to collaborate on translations from the Russian. Mirrlees and Harrison visited Spain in 1920, and there took Spanish lessons.
After Harrison's death, Mirrlees converted to Catholicism. In 1948, Mirrlees moved to South Africa and remained there until 1963, when the first volume of her "extravagant biography" of Sir Robert Bruce Cotton was published (the second volume is unpublished). Two volumes of poetry, Poems and Moods and Tensions, were also privately published.
Mirrlees was a friend of Virginia Woolf,who described her in a letter as "her own heroine – capricious, exacting, exquisite, very learned, and beautifully dressed." Her circle of celebrity friends also included T. S. Eliot; Gertrude Stein, who mentions Mirrlees in Everybody's Autobiography; Bertrand Russell; and Lady Ottoline Morrell.
Mirrlees' 600-line modernist poem, Paris: A Poem, published in 1918 by Leonard and Virginia Woolf's Hogarth Press, was the subject of considerable study by scholar Julia Briggs, and is considered by some literary critics to have had an influence on the work of her friend, T. S. Eliot, and on that of Virginia Woolf.
Mirrlees set her first novel, Madeleine: One of Love's Jansenists (1919), in and around the literary circles of the 17th Century Précieuses, and particularly those salons frequented by Mlle de Scudéry. Mirrlees later used medieval Spanish culture as part of the background of her second novel, The Counterplot (1924).
Lud-in-the-Mist was reprinted in 1970 in mass-market paperback format by Lin Carter, without the author's permission, for the Ballantine Adult Fantasy series, and then again by Del Rey in 1977. The "unauthorised" nature of the 1970 reprint is explained by the fact that, as Carter indicated in his introduction, he and the publishing company could not even ascertain whether the author was alive or dead, "since our efforts to trace this lady [Mirrlees] have so far been unsuccessful."
Since 2000, Mirrlees' work has undergone another resurgence in popularity, marked by new editions of her poetry, an entry in the Dictionary of National Biography and several scholarly essays by critic Julia Briggs, new introductions to Lud-in-the-Mist by writer Neil Gaiman and scholar Douglas A. Anderson, essays and a brief biography by writer Michael Swanwick, and translations of Lud-in-the-Mist into German and Spanish.
Joanna Russ wrote a short story, The Zanzibar Cat (1971), in homage to Hope Mirrlees and as a critique of Lud-in-the-Mist – and indeed the entire genre of fantasy, describing Fairyland "half in affectionate parody, but the other half very seriously indeed".
Hope-in-the-Mist, a book-length study of Mirrlees and her work by Michael Swanwick, was published by Temporary Culture in 2009.
The Collected Poems of Hope Mirrlees will be published by Fyfield Books (Carcanet Press) in 2011 (edited by Sandeep Parmar). It will include previously unpublished poems, the full text of Paris, her later poems and prose essays from the 1920s. Sandeep Parmar is currently writing a biography of Mirrlees as well.
