Although I enjoy finding parallels between fictional works of different genres in different media, page viewers might regard some of my parallels as somewhat bizarre. For example, whereas, in Poul Anderson's History of Technic Civilization (prose sf), Fr Axor seeks evidence for a second Divine Incarnation off Earth, in Jamie Delano's Hellblazer: Original Sins (New York, 1992) (graphic fantasy), John Constantine helps the demon Nergal to sabotage the Resurrection Crusade's attempt at a second Incarnation on Earth. However, Constantine then allows the plant elemental to use his, Constantine's, human body to beget a new "'conjunction between nature and super-nature.'" (p. v) (The figure on this Operation Chaos cover resembles the monster-turned-elemental, Swamp Thing.)
Bizarre, indeed. However, fantasy and sf are two exercises in imagination and intellect: narrative ideas and plots are logically deduced from imaginative premises. See, in particular, Operation Chaoshere, here and here.
