How does this artwork elucidate its Provenance?
A wedding-feast by or after Bosch belonged to the Rubens collection in Antwerp.
The painting at Boijmans was bought in Antwerp by an English painter.  It has been sawed down and the upper corners subsequently shaped into steps.  At the time it showed a portrait and only when the overpainting was removed did the tempera painting of the wedding come to light.  “What was revealed was a poor, not to say, wholly disfigured, painting”.
