This is the symbol used to ward off demons in the darker places of the home and church, which I mentioned recently. Recent experiments suggest it is at least somewhat effective.
In order for us to understand the medieval and renaissance mindset, we have to understand what they were reading.
Trying to rebuild the assumptions and cultural context of the authors of books of magic is essential, and thus becoming well versed in the literary and scientific canon of those eras is helpful and perhaps mandatory.
At the very least, it is deeply beautiful and enriching.
When I pay homage to the ancestors, I add the names of practitioners of magic whom I have known but are no longer among the living.

Djinn are not “demons but nicer, and with an exotic mystique.” That’s wishful thinking, and has a rancid touch of orientalist douchebaggery that its wise to be on guard against.
Practical metaphysics is not the Monster Manual. There’s no need for more flavors of ookie spookie, particularly when the new flavor of month isn’t even truly justified in source texts.
It’s not that there may not be additional species of critter out in the spiritual planes, but faddism is a danger and bad research often leads to bad outcomes.
