Georgiana Houghton (1814-1884) was a Spiritualist medium who, in the 1860s and 70s, produced an astonishing series of abstract watercolours. Detailed explanations on the back of the works declare that her hand was guided by various spirits, including several Renaissance artists, as well as higher angelic beings. Houghton was a prominent figure of the early spiritualist movement in Victorian England, which played a significant role in various spheres of nineteenth-century culture and was later championed by such influential figures as Sherlock Holmes author Sir Arthur Conan Doyle. Houghton’s spirit drawings are remarkably complex and layered watercolors. Technically highly accomplished, their bold colors and fluid forms have a mesmerizing and deeply absorbing effect. Although produced in a very different context, Houghton’s abstract works have close connections to the ways in which 20th century artists developed abstract languages of art to transcend the everyday realm of representation and consciousness. Today, less than fifty of her works are known.
