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 Raisonné. 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. Throughout her life af Klint used research-oriented methods trying to understand the spiritual contexts of the world. She investigated plants and other objects in their geometrical form. Nature was perfect; we humans just needed to look at it more closely. This concept is investigated in Volume V. Produced with the permission of the Hilma af Klint Foundation and featuring introductions by Daniel Birnbaum and Kurt Almqvist, a separate slip cased edition containing all seven volumes will be available in autumn 2021.
