Políptico de Gante
In 1934 the panel of "The Just Judges", which formed the lower left panel of the Ghent Altarpiece, by Jan van Eyck or his brother Hubert Van Eyck was stolen and had not been recovered. Van der Veken decided in 1939 to make a copy of the panel using a two centuries old closet shelf as the support. He made the copy of the missing painting on the basis of a copy that Michiel Coxie (1499-1592) had produced in the mid-sixteenth century for Philip II of Spain and was kept at the Royal Museums of Fine Arts of Belgium. He interrupted his work during the Second World War and resumed work in 1945, this time in the Saint Bavo Cathedral in Ghent where the Ghent Altarpiece had been moved to the Vijdtkapel. In order to harmonize his copy with the appearance of the other panels of the Ghent Altarpiece he applied a layer of wax to create a similar patina. Van der Veken subtly indicated that his work was a copy by giving one of the horsemen the facial features of the then Belgian king Leopold III.
