The University of Chicago is fighting an attempt to seize thousands of ancient, clay tablets from their Oriental Institute. The tablets were brought to Chicago for study in 1937. American survivors of a bombing in Jerusalem nearly a decade ago want the tablets auctioned off as compensation for the attack, which they blame on Iran. But both Iran and the U.S. government say current law does not permit the tablets to be sold.
The OIM web site says this about their tablets: “The collection comprises thousands of original clay tablets inscribed in cuneiform, plus a large number of casts of such tablets excavated by Oriental Institute expeditions but now housed elsewhere.”
