From the artist Wayne Barlowe who wrote the aforementioned novel, God’s Demon.

Quoth:

My book GOD’S DEMON is, in theory, the first of three novels addressing Hell. This image is a bit of a teaser, a glimpse of one the second book’s main characters. For a variety of reasons I’d rather not elaborate upon here, I decided to separate this entity visually from all of the other demons in Hell and go with a somewhat more abstract form. Primitive masks and insects floated before my mind’s eye as I created It.
