Co-incidentally the film has started another round of what belongs to who(m) The Turkish govt is currently "lobbying" ie moaning their bags off at the Russian govt for the return of Schliemann's treasures, that the Rooskies looted from Germany in 1945 as spoils of war, then denied they had them for almost 50yrs, while the Turks have p[ossession of the site and therefore a claim to everything that may or has been found there. Germany is also claiming them saying that they are legitimately theirs because a German found them. The Greek govt wants them as they are from a purely Greek culture and historical background, in the Bronze Age the ancestors of the Turks were living in central Asia.
While in principle I'd like to see them go back to their place of origin, I'm afraid the Turks have a really bad track record of looking after antiquities. You can wander around Turkey and just pick up bits of statuary etc from the roadside or aout of fileds and no-one cares (except when you get to the airport, and there's ways round that too )
Mind you, we've really got no moral high ground over this in Britain, seeing as we've got a huge proportion of the ancient world shoved away in the British Museum that we looted at gunpoint or ripped some farmer off for. Elgin Marbles anyone?
