A 3,000-year-old stone tablet from Babylonia is being flown home after experts in the U.K. verified its provenance and determined that it was likely looted during the Iraq War, Agence France-Presse reports. The tablet was handed over to Iraqi Ambassador Salih Husain Ali during a ceremony Tuesday, putting an end to years of legal work following an initial discovery at London’s Heathrow Airport in 2012. “It is a very important piece of Iraq’s cultural heritage,” said British Museum director Hartwig Fischer, praising the “extraordinary and tireless work” of border officials. The tablet, known as a kudurru, records the gifting of land by the Babylonian king Nebuchadnezzar I to one of his subjects, curator Jonathan Taylor told AFP. The erosion of the stone’s surface makes it hard for historians to glean much more, however. “The basic identification is quite straightforward,” Taylor said.
