ROME — A statue of a human-headed winged bull from the Northwest Palace in Nimrud, Iraq, that was bulldozed by the Islamic State last year to great outcry has been faithfully recreated using modern technology and put on exhibit at the Colosseum in Rome to spur discussion of the possible reconstruction of war-torn archaeological sites.

Full-scale reconstructions were also made of two damaged Syrian sites: the archive room of Ebla and a portion of a ceiling from the Temple of Bel in Palmyra, as examples of how conflict can devastate a nation’s fragile heritage.

“Nimrud was the first place to be destroyed,” said Frances Pinnock, the co-director of the Ebla expedition, the most important Italian archaeological expedition to Syria. “It was a palace known as the Versailles of the ancient Near East, and so it was chosen because it was symbolic.”

“We included Ebla because it represents abandonment, what happens to a site when a mission is no longer present to protect it,” said Ms. Pinnock, who is a member of the scientific committee for the exhibit.
