Pablo Picasso and Alberto Giacometti were godlike creators. The former is credited with the groundbreaking Cubist movement, which led to many offshoot movements—Futurism, Dada, Constructivism, De Stijl, and Art Deco—and the latter is hailed as one of the fathers of modern sculpture. Picasso was 20 years older than Giacometti, but they navigated the same artistic circles and became friends in the spring of 1937. Giacometti frequently visited Picasso’s studio on the Rue des Grands-Augustins, but there was a competitive edge. “Alberto tries to make us regret the works he hasn’t done,” Picasso once said sardonically. Meanwhile, Giacometti secretly judged Picasso’s turbulent family life and his many lovers. It was shortly after 1937 that Giacometti began to make the small figures that led to the large hieratic forms for which he is famous. This exhibition brings the two men together, looking at their shared existentialism and the many facets of their relationship. —E.C.
