The world is now acquainted with both Hilma af Klint, born in 1862, and her art, the colorful abstract paintings that boldly invoke the cosmos and its geometries. But as a young woman, unlike her contemporaries Kandinsky and Mondrian, af Klint’s work was casually dismissed and left to collect dust in the attic. The full extent of her achievement wasn’t recognized until 2018, when a Guggenheim survey of her work unexpectedly broke records for the largest ticket sales in the history of that institution. Recently, a new group of eight watercolors by af Klint—created between 1913 and 1915—came to light. The rare set is on view at Zwirner’s 69th Street location. —E.C.
