Curiosity here. Where did you get the info for the various symbols and circles you used on these pages and some of your other pages? I'm mostly interested in their occult meaning; I haven't seen most of these before.
I used to have quite some books with seals and sigils, which i used to combine in older drawings. Through the years, i started to create my own sigils, some based on authentic ones, others completely made up. An old book i kept, called "de geschiedenis van de hel", deals with the definition of hell through all sorts of religions, centuries, etc... and shows many "autographs/marks" from demons, seals and occult symbols on which i based mine as well. Some of them have a meaning, others are combined just for personal interpretation of the Mythos.
