Completed around 1470 in Bruges, Hans Memling’s extraordinary Triptych of Jan Crabbe was dismantled centuries ago and the parts were scattered. The inner wings from the altarpiece are among the finest paintings owned by the Morgan Library & Museum, where they have long been on permanent view in museum founder Pierpont Morgan’s study. Hans Memling: Portraiture, Piety, and a Reunited Altarpiece, opening on September 2, reunites the Morgan panels with the other elements of the famous triptych: the central panel from the Musei Civici in Vicenza, Italy, and the outer wings from the Groeningemuseum in Bruges, Belgium.
