Hilma af Klint (1862-1944) was a Swedish artist and mystic whose paintings are considered among the first abstract works known in Western art history.
A considerable body of her work predates the first purely abstract compositions by Kandinsky, Malevich and Mondrian.
She belonged to a group called "The Five", comprising a circle of women inspired by Theosophy, who shared a belief in the importance of trying to contact the so-called "High Masters" - often by way of séances.
Her paintings, which sometimes resemble diagrams, were a visual representation of complex spiritual ideas.
