Polyptych - upper half closed by two doors. On the outside of the doors, the Virgin in the Temple (left), Marriage of the Virgin (right); inside the same doors, Moses and the Brazen Serpent (left) and the Deposition (right). Inside the upper half, in deep and delicate relief, the Crucifixion beneath a vaulted roof, staged on several levels.
lower half is shut with one hinged flap which telescopes open, and is carved on both sides: on the front, The Annunciation with the words spoken by the Virgin and by Gabriel within the scene as scrolls; on the other side, The Nativity, with smaller scenes of the Circumcision, Presentation in the Temple and Christ among the doctors. Inside the lower half, carved in deep relief is the Bearing of the Cross with St. Veronica.
