ISIS's unholy business of artefacts

So why is Isis blowing to pieces the greatest artefacts of ancient history in Syria and Iraq?

The archeologist Joanne Farchakh has a unique answer to a unique crime. First, ISIS sells the statues, stone faces and frescoes that international dealers demand. It takes the money, hands over the relics – and blows up the temples and buildings they come from to conceal the evidence of what has been looted.

"Antiquities from Palmyra are already on sale in London," the Lebanese-French archaeologist Ms Farchakh says. "There are Syrian and Iraqi objects taken by Isis that are already in Europe. They are no longer still in Turkey where they first went – they left Turkey long ago. This destruction hides the income of Daesh [Isis] and it is selling these things before it is destroying the temples that housed them.

"It has something priceless to sell and then afterwards it destroys the site and the destruction is meant to hide the level of theft. It destroys the evidence. So no one knows what was taken beforehand – nor what was destroyed."

Ms Farchakh has worked for years among the ancient cities of the Middle East, examining the looted sites of Samarra in Iraq – where "civilisation" supposedly began – after the 2003 US invasion. She has catalogued the vast destruction of the souks and mosques of the Syrian cities of Aleppo and Homs since 2011.

Ms Farchakh says Isis does not destroy all of Palmyra in one video to serve its purpose. "It started with the executions [of Syrian soldiers] in the Roman theatre. Then it showed explosives tied to the Roman pillars. Then it decapitated the retired antiquities director, al-Asaad. Then it blew up the Baal Shamim temple.

The longer the destruction lasts, Ms Farchakh believes, the higher go the prices on the international antiquities markets. Isis is in the antiquities business, is her message, and Isis is manipulating the world in its dramas of destruction. "There are no stories on the media without an 'event'. First, Daesh gave the media blood. Then the media decided not to show any more blood. So it has given them archeology. When it doesn't get this across, it will go for women, then for children."
