In 2012, the Cleveland Museum of Art announced that it had made a “stellar” acquisition: a monumental portrait head of Drusus Minor, the volatile son of the Roman emperor Tiberius. But this impressive marble sculpture was recently removed from its gallery and will not be placed back on display. As Steven Litt reports for The Plain Dealer, museum officials have decided to return the portrait to Italy, after determining that it was swiped from a provincial museum near Naples in the 1940s. 

According to a CMA press release, when the museum first acquired the sculpture, it believed that the artifact had belonged to an Algerian collection since the 19th century. But the history of the sculpture’s ownership was called into question when a companion portrait came on the market.
