This unprecedented co-production between the Grand Palais and Centre Pompidou finally brings Hilma af Klint's visionary work to France. Long before Kandinsky or Malevich, she painted radical abstractions—spirals, cosmic diagrams, and monumental color fields—inspired by spiritualist séances and Theosophy. The exhibition reveals her secret magnum opus, the Paintings for the Temple cycle (1906–1915), including the legendary Ten Largest series, kept hidden for decades at her own request and unseen until 1986.
