Hilma af Klint is now regarded as a pioneer of abstract art. Her work from the early 20th century predates the first purely abstract paintings by Kandinsky, Mondrian and Malevich. Now, for the first time, af Klint’s works, some 1,600 in all, have been collected in a Catalogue Raisonne. Af Klint’s work should be seen and appreciated in the series of paintings often depicting specific themes and this ground-breaking publication, divided into seven volumes, allows for this. Volume IV, within the series Parsifal she explored her inward self through the journey of a boy and a girl and their various levels of consciousness. In her Atom series, af Klint explored the inner parts of our existence through what scientists then considered the smallest particles in the world.
