Hilma af Klint 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.

Abstract art uses visual language of shape, form, color and line to create a composition which may exist with a degree of independence from visual references in the world.
