o drap'd figure where is thy top half?

Since the top of the figure IS missing, one can read the inscription that asks,
O death where is thy sting
O grave where is thy victory
Was the figure always incomplete, or is it Mother Nature's dark humor that's weathering the stones at Greyfriars Kirkyard? The nearby Flodden Wall, in contrast, stands strong after 500 years, and is testament to a more sobering event of a Gettysburg hue, although probably not the darkest.
