What if experts discovered a vast collection of works by an unknown artist who would completely rewrite modernist art history? That’s exactly what’s happened—with the added significance that the artist was a woman. Sweden’s Hilma af Klint is now largely credited with painting the western world’s first abstract work, in 1906, several years before Wassily Kandinsky took that credit. This exquisitely crafted and engaging documentary celebrates af Klint’s expressive, and unabashedly feminine, masterpieces—which look like they come straight out of today’s galleries, with their blend of the mystical and the natural worlds.

Interviews are interspersed with reenactments of af Klint painting the huge, swirling pieces laid out on a floor, as she was known to do.
