Some extremely clever person took the image above, which was published in the Rosicrucian pamphlet Speculum sophicum rhodostauroticum – 1618, and worked out the sacred geometry encoded there.

He also found several other hidden secrets in the lines, including something that corresponded exactly with the Cygnus Constellation.

I’m out of my depth here but willing to learn more :o)
