Molanus criticises a particular type of statue of the Virgin Mary that could be opened up and held an image of the Trinity in this inner compartment. According to him, this creates a wrong illusion about the relationship between Virgin Mary and the Trinity.
Molanus explains the iconography of Virgin Mary trambling the Devil with her feet as the depiction of her life free of sin and her virginity.
Molanus concludes that a certain pictorial tradition of an unestablished story does not mean this story has become certain, but that this way of depicting is most probable.
Molanus argues that a recurrent depiction of the Virgin Mary during labour is incorrect and deviates from the Holy Scriptures and the teachings of the Church.
Molanus disapproves of artworks depicting apocryphal stories of Jesus and the Virgin Mary.
Artists follow the traditions of depicting Christ, Mary, and Apostles either by studying other paintings or the authorities
Molanus argues that artists should follow the pictorial tradition set by other artists or study the written sources regarding the subject.
