OP, I guarantee the Artist is a Gnostic Occultist. I do recognize the style amongst a handful of designers and had a friend that worked for coca cola ads and attended the Denver Art School that told me some of the biz.

I estimate there are around 20 top Gnostic/Esoteric designers around the world

They also design the Fleur di Lis that is everywhere which is Gnostic family crest.
