In this picture taken in 2014, the medieval portable altar of Eilbertus a part of the Guelph treasure, is displayed at the Bode Museum in Berlin. The treasure’s complicated history found itself at the U.S. Supreme Court.

In this picture taken Jan. 9, 2014 the medieval portable altar of Eilbertus a part of the Welfenschatz, is displayed at the Bode Museum in Berlin. One of Germany’s most precious collections of medieval Christian art is at the center of a complicated ownership dispute between the foundation that oversees the Berlin museums and the heirs of Jewish art dealers who claim their ancestors had to sell the objects to the Nazis under pressure in 1935. For years, both sides have claimed they’re the legitimate owners, arguing their cases without finding a successful solution, so on Wednesday Jan 15, 2014, in a highly anticipated meeting, a German government-created commission will come together to make a recommendation on who should rightfully own the so-called Welfenschatz -or Guelph Treasure.
