Hilma af Klint was an abstract artist before the term existed—a visionary, trailblazing figure who, inspired by spiritualism, modern science, and the riches of the natural world around her, began in 1906 to reel out a series of huge, colorful, sensual, strange works without precedent in painting. The subject of a recent smash retrospective at the Guggenheim Museum, af Klint was for years an all-but-forgotten figure in art historical discourse before her long-delayed rediscovery. Director Halina Dryschka’s dazzling, course-correcting documentary describes not only the life and craft of af Klint, but also the process of her mischaracterization and erasure by both a patriarchal narrative of artistic progress and capitalistic determination of artistic value.
