In this story, an acclaimed sculptor retreats to a mountain-top castle to work on his greatest creation, a sculpture called "Good Versus Evil", two battling giants, one made from earth taken from sacred ground, the other from places of infamy, and built from the skeleton out. Somehow a lightning strike brings Evil to life, and on a rampage, but some unknown also brings Good to life, in time to rescue the sculptor and battle his rival, sending them both plunging off Bald Mountain to their doom.
I assume Ditko really liked these kinds of stories, given how often he returned to similar themes and visual motifs (allegorical sculptures and the like) in his later work that he wrote himself. I especially love the panel in this story of the artist first building the skeletons of the figures.
You know, I never considered it before, but given how often sculptors figure into Ditko's work, I wonder if he ever tried his hand at the form?
