Georgiana Houghton @ Courtauld Gallery

Georgiana Houghton (1814-1884) was a Spiritualist medium who, in the 1860s and 70s, produced an astonishing series of largely 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. In 1871 Houghton rented a gallery in Bond Street and presented 155 of these works to an astonished London audience.  The exhibition is called Spirit Drawings.
