During the XVth Century one seldom finds a representation of the Death of the Virgin as the central theme of a tryptich. The Holy Spirit floating over the globe is as unusual for the iconography of this theme, as are the diabolic beasts abounding in the ground. The latter, just as the fly and the spider on the bedside are meant as symbols of sin. The decoration of the deathbed of Mary is reminiscent of the representations of the Arc of the Covenant. The commission of the tryptich is to be seen in the context of contemporary discussions over the Immaculate Conception. However, it is not anymore possible for us to decide which side's arguments were meant to be supported by this painting. The apostle lifting up a censer belongs to the same Rahmenthemen as the doctor lifting up the uroscope.
