London’s Islamic art sales concluded last week with a notable absentee – Saif al-Islam Gaddafi. It turns out that the son of the Libyan leader was a buyer of mid-range items at previous auctions. Bidding through a London-based agent, he was collecting for an as-yet-unfinished museum of Islamic art in Tripoli. This buying has now stopped but Islamic art dealers were buzzing with the news that some consignors have been contacted because an unidentified buyer has failed to pay for purchases at the sales last October. From there, many concluded that Saif Gaddafi could be involved. Sotheby’s and Christie’s refused to comment.
