After a long battle two rare sixth-century B.C. marble sculptures that once belonged to the New York businessman Maurice Tempelsman go on view Tuesday at Italy's presidential palace. For nearly 30 years rumors circulated that tomb robbers had dug up the statues on a hillside in the ancient Greek settlement of Morgantina in Sicily. After amassing evidence that they were looted, Italian investigators began seeking a handover of the acroliths statues usually made with wooden torsos but with stone heads and extremities in the late 1980s. Mr. Tempelsman, a diamond importer perhaps best known for having been the companion of Jacqueline Kennedy Onassis, remained unswayed until the Italian government threatened to sue him, an official said Monday. "He hadn't wanted to give them up because he'd paid for them; that's what he told me," said Mario Bondioli Osio, who formerly headed of an Italian commission that sought to recover the country's lost cultural patrimony. Mr. Tempelsman, who was said to be traveling and unavailable for comment, bought the acroliths from the London dealer Robin Symes in 1980 for a reported 1 million. In 2002 Mr. Bondioli Osio, Mr. Tempelsman and the University of Virginia worked out a deal under which Mr. Tempelsman would give the university partial ownership of the statues for five years and then cede them entirely. On Jan. 1 the acroliths their wooden bodies long ago lost, leaving two heads, three hands and three feet became the property of the university, which promptly returned them to Italy. The statues, one of which is shown above, arrived in Rome on Friday along with nine classical antiquities from the private collection of the New York philanthropist Shelby White that were ceded to Italy in January under a separate pact. Italy says Ms. White's artifacts were also looted from Italian soil.
