An auctioneer doing a routine property inspection in Paris walked into a townhouse and came out with one of the most significant art discoveries in years. The painting on the wall had not been seen by the art world for over four centuries.

A Routine Visit That Changed Everything

Jean-Pierre Osenat, founder of the Osenat auction house in Versailles, had appraised thousands of properties. In September 2024 he was called to a Paris townhouse to assess its contents before a sale. Among the items hanging on the wall was a painting of the crucifixion. He took it to Antwerp.

Known Only Through Engravings

Peter Paul Rubens completed Christ on the Cross in 1613. It was documented at the time - other artists made engraved reproductions of it - and then it simply disappeared. For over 400 years, art historians knew the painting existed but no one could find it. The last recorded owner was the 19th-century French painter William Bouguereau, after which it passed through his family and was lost to the public record entirely.

The Call That Confirmed It

The Centrum Rubenianum in Antwerp - the official Rubens research committee - agreed to examine the work. Art historian and Rubens expert Nils Buttner led the authentication. Microscopic analysis of the paint layers revealed blue and green pigments precisely consistent with Rubens' known technique for rendering human skin. When the analysis was complete, Buttner called Osenat directly: "Jean-Pierre, we have a new Rubens."

Sold After 400 Years of Silence

The painting went under the hammer at the Osenat auction house in Versailles on November 30, 2025. It sold for 2.3 million euros ($2.7 million). For four centuries it had passed quietly through private hands, as the art world searched for it armed with nothing but engravings of a canvas they had never seen.
