When I visited Rome for the first time, which again was recently, about five years ago, it's hard not to notice that there's a number of obelisks. My first thought was, I wonder why they would build Egyptian hieroglyphics and being an idiot. Of course, they didn't build them. The French took many things from Rome and the British made them give many of them back. They couldn't get all of them. As you point out about maybe about half, some of the more important ones got returns.
