In reply to jethro kiernan: You mean its actually a metaphor for man's misuse of the environment? The one, lonely stump reaching up, as if for help, to a dull, lifeless, helpless sky? The crowding trees representing humankinds crowding of our stricken planet. And the slope, ah yes the slope, leading down, down, down to Gates of Hades, sombre in funereal black.
Or, it could just be a deid tree.
