Visitors to Rome can now see one of the most important private collections of ancient Greek and Roman marble sculptures. The 90 works from the Torlonia Collection opened this week in the newly rebuilt Palazzo Caffarelli, overlooking the Roman Forum. Among the works is a marble fountain that was made in ancient Greece. Experts on ancient Rome believe the fountain once stood in the garden of the general and statesman Julius Caesar. At the time, it was already hundreds of years old. The 620-piece Torlonia collection is believed to be the greatest private collection of classical art in the world.
