I’ve found something that explains it as the Eye of Providence. It’s on our one dollar bill.
The symbol may have had Egyptian roots trying to explain their god watching over them but now has become Christianized into Christian symbolatry just as people have. There is no more Egyptian culture calling the Pharoah god and they didn’t have the full knowledge of Our eternal all-knowing God through Jesus but there is Christianity which continues because we’ve received the knowledge of God through the Holy spirit.
Jesus converts not only people but cultures.
When I see it it brings me to think of the eye of God or the beatifiic vision.
By the way there is already a post started on this.
