The tree at the centre separates the worlds of the Old and New Covenant. On one side the branches are bare, on the other side leaved. The Old Testament man (foreground, left), who was driven out of Paradise (background, left) and then condemned by the law (represented by Moses with the ten commandments and two prophets (?) on the right behind him), is driven into damnation (purgatory, foreground left) by Death and the Devil. At the top left Christ is shown as the Judge of the World. On the right side St John the Baptist shows a naked sinner the crucified one, blood spurts from his chest and falls on the Believer's head. On the far right the resurrected Christ stands in front of his tomb, triumphant over the dragon (Death) [sic] and a skeleton (Hell) [sic]. In the background the adoration of the brazen serpent is shown as the antetypus of the crucifixion, the Virgin = Mary is represented praying on a hill. An interpretation has yet to be found for the old man in the foreground on the right.
