“It took me four years to paint like Raphael,” said Pablo Picasso, “but a lifetime to paint like a child.” Picasso began producing art in 1894, the year he turned 13, and his career stretched long beyond his contemporaries, continuing until his death, in 1973. The last decade of his life was imbued with a sense of urgency and intensity, as he withdrew from the public eye and took his energy to the studio. While the many groundbreaking phases of his career are under constant scrutiny, his late work, extremely exploratory, is comparatively unexamined. This exhibition at Moderna Museet highlights more than 50 works from those years, final expressions of unbridled creativity. —Maggie Turner
