Matthias Grünewald and Niclaus of Haguenau - Isenheim Altarpiece, Underlinden Museum at Colmar, Alsace - France. (1512-1516)
The altarpiece has two sets of wings, displaying three configurations:
Wings closed: with the exception of certain holy days, the wings of the altarpiece were kept closed, displaying The Crucifixion framed on the left by the martyrdom of Saint Sebastian pierced by arrows, and on the right by Saint Anthony the Great, remaining placid although he is being taunted by a frightening monster.
Outer wings opened: the outer wings of the Isenheim Altarpiece were opened for important festivals of the liturgical year, particularly those in honour of the Virgin Mary. Thus are revealed four scenes: the left wing represents the Annunciation during which the archange Gabriel comes to announce to Mary that she will give birth to Jesus, the son of God.
Inner wings opened: the sculptures of Saint Augustine and Guy Guers, Saint Anthony, Two Bearers of Offerings, Saint Jerome, Christ and the Twelve Apostles are by Niclaus of Haguenau. Visit of Saint Anthony to Saint Paul the Hermit and Saint Anthony tormented by Demons.
