 The Annunciation draws heavily on van der Weyden 's 1430s Louvre Annunciation , his c . 1455 Saint Columba altarpiece , and the Clugny Annunciation ( c . 1465 – 75 ) , which is attributed to either van der Weyden or Memling . Memling almost certainly was apprenticed to van der Weyden in Brussels until setting up his own workshop in Bruges sometime after 1465 . Memling 's Annunciation is more innovative , with motifs such as the attendant angels that were absent in the earlier paintings . According to Till @-@ Holger Borchert , not only was Memling familiar with van der Weyden 's motifs and compositions , but he might have assisted with the underdrawing in van der Weyden 's workshop . The shutters on the right are copied from the Louvre panel , the knotted curtain appears in the Columba triptych 's " Annunciation " .
