Art for him did not consist in the search for the hidden laws of beauty - for him it could have only one aim, the aim of all religious art in the Middle Ages - that of providing a sermon in pictures, of proclaiming the sacred truths as taught by the Church. The central panel of the Isenheim altarpiece shows that he sacrificed all other considerations to this one overriding aim. Of beauty, as the Italian artists saw it, there is none in the stark and cruel picture of the crucified Savior. Like a preacher at Passiontide, Grunewald left nothing undone to bring home to us the horrors of this scene of suffering: Christ's dying body is distorted by the torture of the cross; the thorns of the scourges stick in the festering wounds which cover the whole figure. The dark red blood forms a glaring contrast to the sickly green of the flesh. By His features and the impressive gesture of His hands, the Man of Sorrows speaks to us of the meaning of His Calvary. His suffering is reflected in the traditional group of Mary, in the garb of a widow, fainting in the arms of St John the Evangelist, to whose care the Lord has commended her, and in the smaller figure of St Mary Magdelene with her vessel of ointments, wringing her hands in sorrow. On the other side of the Cross, there stands the powerful figure of St John the Baptist with the ancient symbol of the lamb carrying the cross and pouring out its blood into the chalice of the Holy Communion. With a stern and commanding gesture he points towards the Savior, and over him are written the words that he speaks (according to the gospel of St John iii. 30): 'He must increase, but I must decrease.'
There is little doubt that the artist wanted the beholder of the altar to meditate on these words, which he emphasized so strongly by the pointing hand of St John the Baptist. Perhaps he even wanted us to see how Christ must grow and we diminish. For in this picture, in which reality seems to be depicted in all its unmitigated horror, there is one unreal and fantastic trait: the figures differ greatly in size. We need only compare the hands of St Mary Magdalene under the Cross with those of Christ to become fully aware of the astonishing difference in their dimensions. It is clear that in these matters Grunewald rejected the rules of modern art as it had developed since the Renaissance, and that he deliberately returned to the principles of medieval and primitive painters, who varied the size of their figures according to their importance in the picture. Just as he had sacrificed the pleasing kind of beauty for the sake of the spiritual lesson of the altar, he also disregarded the new demand for correct proportions, since this helped him to express the mystic truth of the words of St John.
Grunewald's work may thus remind us once more that an artist can be very great indeed without being 'progressive', because the greatness of art does not lie in new discoveries. That Grunewald was familiar with these discoveries he showed plainly enough whenever they helped him to express what he wanted to convey. And just as he used his brush to depict the dead and tormented body of Christ, he used it on another panel to convey its transfiguration at the Resurrection into an unearthly apparition of heavenly light. It is difficult to describe this picture because, once more, so much depends on its colors. It seems as if Christ has just soared out of the grave, leaving a trail of radiant light - the shroud in which the body has been swathed reflecting the colored rays of the halo. There is a poignant contrast between the risen Christ, who is hovering over the scene, and the helpless gestures of the soldiers on the ground, who are dazzled and overwhelmed by this sudden apparition of light. We feel the violence of the shock in the way in which they writhe in their armor. As we cannot assess the distance between foreground and background, the two soldiers behind the grave look like puppets who have- tumbled over, and their distorted shapes only serve to throw into relief the serene and majestic calm of the transfigured body of Christ.
