One of the consequences of watching horror movies is the interest in the origins of various monsters. Since many such films feature demons, their backgrounds and origin stories have always been a point of curiosity. Time is always an issue and Juanita Feros Ruys obliges that hurried sense by packing a lot of information into her short book Demons in the Middle Ages. Covering the basics in the introduction, she moves on to discuss demons in the desert—the bane of the early monastic, and demons in the monasteries of populous Europe. A chapter on the Scholastics describes how early science was applied to incorporeal beings, and a final chapter on learned magic, i.e., raising demons via magic books, finishes off this brief study.
What is particularly striking here is that the Bible says surprisingly little on the topic. It says, however, just enough to kickstart the Late Antique and Medieval interest in the subject. Vast amounts of speculation were raised in the Middle Ages concerning what exactly demons were and what they were made of and what they could or couldn’t do. Ruys points out the trajectory of the male necromancer giving way to the female witch just as early modernity was getting started. The results, we all know, were horrific. Throughout it is remarkably clear that belief in demons was strong. People took them very seriously—the Bible says they’re there, so there. Belief, as always, has consequences. Beginning with the Scholastics, however, a reasoned understanding of the spiritual world was deeply desired.
Reason and faith aren’t really the strangers they’re often portrayed to be. Medieval monks could be quite clever and scientific in their outlook. Human mental faculties, created, as they believed, by God, were necessarily good. Something I’d never considered, but which Ruys explores, is the belief that God cannot experience emotions. Being an “unmoved mover” meant not experiencing emotion (which, she points out, includes a noun of movement). This also meant that demons, according to some, had no feelings. This is a very cold spiritual world, particularly when it’s put into conflict with the human one. Spiritual, rational beings subjected to emotions, we’re the ones at the mercy of supernatural beings more powerful than us, yet incapable of the warmth we crave. About a millennium and a half of shifting beliefs in demons crowd this tiny book. Although not intended to be especially profound, it gives the reader plenty to ponder. Including why some of us watch horror movies at all when religion can do the trick all by itself.
