David Carrier reviews the book Hilma af Klint: The Art of Seeing the Invisible, edited by Kurt Almqvist and Louise Belfrage (Ax:son Johnson Foundation, 2015).

Although finding certain aspects of the text wanting, Carrier concludes "Perhaps … to understand af Klint we need to avoid a rigid distinction between spiritualist diagrams and abstract painting. After all, Renaissance altarpieces, which originally served sacred functions, nowadays are treated as works of art and so placed in museums."
