Nativity Triptych 1460s Oil on oak panel, 140 x 193 cm (central panel, 89 x 43 cm (each wing) Metropolitan Museum of Art, New York This free copy of Rogier van der Weyden's Middelburg Altarpiece (Staatliche Museen, Berlin) derives not from the completed work itself but from Rogier's sketched design for it, which included the inscription scrolls that were later left out. The anonymous painter must either have seen these sketches and other models in Rogier's workshop, or copied them from material left on his death; the quality of the triptych, however, is not good enough to make it a product of Rogier's workshop.Artist:UNKNOWN MASTER, Flemish Title: Nativity Triptych Painted in 1451-1500 , Flemish - - painting : religious
