I was trying to find a significance of Redrum in The Shining, the Kubrick version.....I know it's murder backwards. But I found this in the table of the goetia demons.....it sounds like his name backwards.....without the Red. Close. Knifes symbolize air, knowledge, mental clarity (or not).
Here's the description:
(g) Pseudomonarchia daemonum - Johann Wier (1583)
Murmur is a great duke and an earle, appearing in the shape of a souldier, riding on a griphen, with a dukes crowne on his head; there go before him two of his ministers, with great trumpets, he teacheth philosophie absolutelie, he constraineth soules to come before the exorcist, to answer what he shall aske them, he was of the order partlie of thrones, and partlie of angels, and ruleth thirtie legions.
