In the Basilica of Saint Mary Magdalene in Vézelay, many column capitals are decorated with depictions of Christian stories. The representation shown in this picture visualizes the story of the Mystic Mill. It depicts two figures. One pours grain into a mill, and the other collects the processed flour in a bag. The image is unique in Romanesque sculpture and does not seem to depict any known biblical story. However, a stained glass window in the Abbey of Saint-Denis (France), created around 1140, identifies the figures in this representation as Moses and Saint Paul. This identification helps understand the image as an allegory of the transformation of the Old Laws from the Old Testament to the New Laws of the New Testament. The cross within the mill-wheel symbolizes the transformation process of the mill and Christ's journey to the cross.
