The meaning of the saints heads surrounded by a circle means they were all hypnotized. 2000 years ago people believed hypnosis to be supernatural shit. The truth is that hypnosis is a genetic inborn defect of human brain. Hypnotized brain becomes corrupted and loses the capacity of logic, therefore loses the capacity of analytical and critical thinking. The problem is that the demented degenerates still believe hypnosis to be something occult and esoteric. Stay away from demented christians and satanists.
