Barbara's panel. Brand Philip noted the similarities between the panel and Dürer's 1514 charcoal drawing Portrait of the Artist's Mother at the Age of 63. Fedja Anzelewsky agreed with the attribution, noting that both portraits bear, on their reverse, the catalogue number recorded in the Imhoff inventories, as well as "precisely the same design of masses of dark clouds". Anzelewsky speculated that the father's portrait, which was not listed in the 1628 Imhoff inventory, had been broken off and sold to Rudolph II of Austria. Hans Hieronymus Imhoff's lukewarm description of Barbara's portrait—"the mother of Albrecht Dürer in oil colors on wood, [but] there are many who do not believe it to be a work of Dürer"—led Brand Philip to conclude that Albrecht's panel was likely sold individually as the more accomplished and marketable of the two. The attribution is widely accepted today. In 2013 Stephan Kemperdick noted the sophistication of the Nuremberg portrait and that its three-dimensional modeling of the head displays a level of skill beyond Wolgemut and his circle. The two panels were reunited in 2012 during a Dürer exhibition in Nuremberg having been separated since sometime between 1588 and 1628. References Notes Citations Sources Allen, L. Jessie.
