I was thinking it looks like the caduceus. It just so happened that I was reading Simanek's report for the first time tonight. Literally, 3 minutes ago. I read this "At the center is the sun, an invisible electro-magnetic battery in the form of a helix . . ." So I started thinking that the sun is a double helix. And that "fire rainbow" was an image of the sun's center. Remember Moses had the Israelites stare at the two serpents on the staff. Perhaps this was a form of sun gazing for healing purposes as some people still do today. As do I.
