Mexico City -- The Mexican government is demanding that the Sotheby's auction house halt the planned sale of 51 pre-Colombian Mexican artifacts, arguing they are protected national historical pieces.
The National Institute of Anthropology and History says Mexico has sent a diplomatic note to the French government seeking assistance in heading off the sale scheduled in Paris for Friday and Saturday.
A description of the pieces listed on the French website of Sotheby's describes the collection as containing sculptures from Mexican and other pre-Hispanic cultures.
Sotheby's did not immediately respond to a request for comment.
A statement issued by the Mexican institute Wednesday says it objects to "the international trade in protected cultural objects" and says the pieces are "property of the nation."
