One story tells how during a terrible famine, a malicious butcher lured three little children into his house, where he killed them, placing their remains in a barrel to cure, planning to sell them off as ham. Nicholas, visiting the region to care for the hungry, saw through the butcher’s lies and resurrected the pickled children by making the Sign of the Cross…

Though this story seems bizarre and horrifying to modern audiences, it was tremendously popular throughout the late Middle Ages and the Early Modern Period and widely beloved by ordinary folk. It is depicted in stained glass windows, wood panel paintings, tapestries, and frescoes. Eventually, the scene became so widely reproduced that, rather than showing the whole scene, artists began to merely depict Saint Nicholas with three naked children and a wooden barrel at his feet. According to English, eventually, people who had forgotten or never learned the story began misinterpreting representations of it. The fact that Saint Nicholas was shown with children led people to conclude he was the patron saint of children; meanwhile, the fact that he was shown with a barrel led people to conclude that he was the patron saint of brewers.
