Capitoline Wolf created in the Middle Ages?

One of the most famous symbols of Rome is the Capitoline Wolf, a bronze statue depicting a mother wolf suckling Romulus and Remus. But now experts believe the statue was created during the Middle Ages, with parts as late as the 15th century.

Researchers at the University of Salento used radiocarbon and thermoluminescence tests to determine the real age of the Capitoline Wolf which they believe is sometime in the 12th century. The twins may have been added in the 15th century.
