lost jesus painting peter paul rubens paris mansion osenat

A long-lost painting of Jesus Christ's crucifixion by 17th-century Flemish master Peter Paul Rubens, titled *Christ on the Cross* (1613), was discovered in a Parisian mansion by auctioneer Jean-Pierre Osenat last September. The large Baroque work, measuring 42 by 29 inches, was authenticated by German curator and art historian Nils Buttner, chairman of the Centrum Rubenianum, through X-ray imaging and pigment analysis. It will be auctioned by Osenat's auction house in Fontainebleau on November 30, with no estimate yet released.
