The Altarpiece at its least Peaceful

Otto Dix's War Altarpiece or Triptychon Der Krieg (1929-1932):

Matthias Grünewald's Isenheim Altarpiece (1512-1516):

The Isenheim Altarpiece was made for a "hospital" or really more like a hospice for folks suffering from St. Anthony's Fire or ergotism. 

Thanks for the inspiration Mr. Hotdog
