The altarpiece is divided horizontally into heavenly and earthly spheres. The upper section shows Christ offering a crown to his mother, who is placed above her empty sarcophagus. Confronting her disappearance and replacement by miraculous flowers, the startled apostles are grouped around the massive stone coffin in the panel's lower area.
When closed, the altarpiece has on the outside of its wings a large Annunciation, the angel Gabriel and the Virgin being separated by two small panels. Above the angel, in the lunette, Prophet Micheas is depicted. The Latin name of the Prophet is indicated on the frame.
