Although some treasures may have been acquired illegally, the evidence for this is often ambiguous. Experts agree that Greece could mount no court case because Elgin was granted permission by what was then Greece's ruling government. Lord Elgin’s bribes were the common way of facilitating any business in the Ottoman Empire, and do not undermine Britain’s solid legal claim to the Parthenon marbles, based upon a written contract made by the internationally-recognised authorities in Athens at the time. The veracity of the document can never be fully dismissed as it is a translation. And while some Benin bronzes were undoubtedly looted, other “colonial trophies” were freely sold to the imperial powers, indeed some were made specifically for the European market.
