It's an entrancing picture.
It reminds me of a story I once read, where a guy is playing around with black magic. He draws a pentagram on the floor, and a demon appears bound in it. Of course, the guy is in trouble now. Nor can he get rid of the demon. The only thing he can do is draw another pentagram, and the demon will have to move to be bound in that one instead.
Then he hits upon a way to get out of this mess.
He draws the pentagram on the belly of the demon.
(Sorry, but I have forgotten the name of the story and the author).
