One of the highlights in the exhibition is a painting by Jan Steen. It shows a family celebrating Sinterklaas. One of the children has been given a stick, that stick is the rod. There was no singing at that time Those who are sweet get treats, those who are naughty get the rodbecause the rod had a completely different meaning. If a child had been given the rod then, he would have reached the age where he no longer received presents.
