I'm sure most people haven't been following this, but for awhile now Italy has been suing the Getty over about 50 pieces of art that they claim are stolen and want returned. They just reached a settlement which involves returning most of the items, including a 5th century BC statue of Aphrodite, but are still wrangling over one of the pieces, the 3rd century BC "Getty Bronze," aka the "Victorious Youth."

However someone questioned why the Getty was returning greek artifacts to italy, so i was looking through wiki about the two named items. The Aphrodite one they are returning is from a Greek settlement on Sicily, so that one's a bit tricky. However the "Victorious Youth" article above says that it was reclaimed from a shipwreck, probably of a Roman vessel returning home with looted goods.

So Italy is pissed that the Getty is unjustly stealing what they rightfully looted :)
