Museum Mondays: Kobell’s Siege of Cosel, a study in breaths of gray

The Siege of Cosel, which was painted around 1808 is like a woman covered in veils. Gossamer layers of gray, recede ever fainter as he paints the foggy battle scene. Textbooks do not show this well. Even though the painting is massive — larger than a wall in most homes — these figures are sometimes as small as the head of a pin, only visible less than a foot away from the canvas. Seeing them makes the average museum guard nervous as you move scant inches from the canvas.
