The chart is welded together

Woodroffe's Serpent Power puts the six wheels into English in 1919. Leadbeater's The Chakras adds the rainbow in 1927. The Golden Dawn's habit of mapping everything onto the Tree supplies the correspondence.

Eight years, two books, and a diagram that is now on every wall. The app dates it, keeps it, and refuses to antique it — the same treatment given to the Kybalion's 1908 and Kircher's 1652.
