After being taken by German authorities, it was handed over to Michael Müller-Karpe in Mainz for analysis. Müller-Karpe is a a leading expert on Mesopotamian metalwork. He concluded it was of Iraqi origin and unlikely to have come from Troy, the provenance claimed by the auction house. He believed it more likely would have been deposited in a royal grave at Ur.
After a delay (discussed in the previous posts), Müller-Karpe and his institution returned the vessel to German authorities though the Iraqis feared the German government would allow the sale of this allegedly stolen object.
It has recently been reported that the Iraqis have successfully blocked the sale of the gold vessel and that it has returned to Iraq (S. Adel, "Iraq blocks sale of Mesopotamian artifacts in German auction," Azzaman News, 14 October 2009) . Since the American-led invasion of Iraq in 2003, the Iraqis have successfully blocked the sale of 28 suspect items in Germany.
