“Her work oscillates between the delicate mythological approaches,” the curator Bettina M. Busse says of the German artist Rebecca Horn, “and brings at the same time the full brutality of life.” At 20, Horn worked with glass fibre without a mask and damaged her longs. After a long convalescence she returned to art, but increasingly focused on bodily forms. Horn embraces the paradoxical—strength versus weakness, for instance. A sense of poetry, fragility, permeates her work, whether it’s performance, drawing, film, or kinetic sculpture. She often uses wings and white feathers to suggest a sense of fallibility infused with the mystical. This exhibition is Horn’s first large retrospective in Austria in the last 30 years. —E.C.
