Golden Dawn Guys & Gals
Hi Ravenest,
Yes, there are 3 double triangles (top and bottom) aka "septenaries" across from left to right. The last triangle, aka "ternary" is just the top triangle because it is made up of the last 3 cards, which is Sun, Judgement, and World....with Fool left over. It is the end of that journey through the deck. So, if you have room on the board you could put the last triangle/ternary alongside the 3 septenaries. Then you would have 4 triangles across the top of the board and three triangles that make up the bottom triangles....no bottom triangle for the 4th/last one.
A lot of people are put off by the seeming difficulty of this Papus method, but once you understand what the pattern is, the layout creates itself. It is a most enlightening layout. Supposedly based on the Kabbala, but those Golden Dawn guys argued so much about which card fit the Kabbala alphabet that this sort of fell by the wayside. I also laid out the Tree of Life, and still have it laid out next to this one, but I find the Papus one resonates for me. I have learned so much from it
You are right about it being easy...it is. Once you lay it out and get familiar with it, you will be able to visualize it without any effort at all.
