We explore the lives and work of a group of extraordinary women, from the twelfth-century mystic, composer, and artist Hildegard of Bingen to the nineteenth-century English spiritualist Georgiana Houghton, whose paintings swirl like a cosmic Jackson Pollock; the early twentieth-century Swedish artist, Hilma af Klint, who painted with the help of her spirit guides and whose recent exhibition at New York's Guggenheim broke all attendance records to the 'Desert Transcendentalist', Agnes Pelton, who painted her visions beneath the vast skies of California. We also learn about the Swiss healer, Emma Kunz, who used geometric drawings to treat her patients and the British surrealist and occultist, Ithell Colquhoun, whose estate of more than 5,000 works recently entered the Tate gallery collection. While the individual work of these artists is unique, the women loosely shared the same goal: to communicate with, and learn from, other dimensions.
