Determining the exact date of the painting
What was the most important discovery? The work was dated incorrectly. Examination of the layers of paint proved that the panel does not date from 1561 but 1563. A further remarkable revelation was the confirmation by XRF images that the word dul ('mad with rage'), which appeared to have been inscribed on the painting, was just an accidental scratch in the preparatory layer. Previously, it was seen as a reference to the title of the painting.
Restoring the original colours
The restoration process removed the heavily yellowed varnishes and localised overpainting from the original paint layer. The bright colours have been restored to their former glory, and the scene has recovered its space and depth. Dull Gret's wooden support has also been adapted for optimal conservation. In this way, many future generations of art lovers will still be able to enjoy this fantastic masterpiece.
