Those buying antiquities that had once allegedly passed through the Lebanese market need to be on their guard when conducting their due diligence search. Items include the major silver hoard, the Morgantina treasure, that was clearly derived from Sicily. The Sevso treasure was claimed to have been derived (among a number of locations). The Sarpedon krater was reported to have a Beirut connection. Likewise the statues of the Dioskouroi on loan to New York's Metropolitan Museum of Art are linked to Sidon when other documentary evidence points to a findspot in Syria.
Back in 2010 I even draw attention to Late Antique (Byzantine) mosaics with a Lebanon link. Does this sound familiar?
