Workshops routinely produced copies of paintings that were coveted for their spiritual powers or for the status of their authorship and/or ownership. Such factors prompted Queen Isabella of Castile to order a copy of Rogier van der Weyden's "Mary Altarpiece" (Gemäldegalerie, Berlin), which was given by her father, King Juan II, to the Carthusian monastery of Miraflores, near Burgos, Spain, in 1445. This picture is the right panel of Isabella's triptych and can tentatively be attributed to her court artist Juan de Flandes on the basis of documentary and technical evidence.
