If there was a statute of limitation on stolen artifacts, the British Museum's years of ownership of the Rosetta Stone has past it. After all, Egyptology was but a fetus when the Napoleonic expedition discovered it and there were no rules that detailed who got what upon discovering Egyptian artifacts. However, it is a very significant (and iconographic) artifact that plays one of the greatest roles to Egyptology...the re-learning of the ancient literary language of the Egyptians, that is! My goodness! If Hawass can regain this artifact, then the Germans should have no more excuses to withhold the bust of Nefertiti from her native country!
