Consequently, to modern day, two versions are widely circulated: one where Malkuth has 1 path, owing to Reuchlin's original; and another where Malkuth has three paths, owing to several later versions; both having 22 paths in total, corresponding each to a Hebrew letter, owing to Kircher's syncretism. With the resurgence of occultism in the 19th century, many new versions appeared, but without major innovations. In the 20th century, Aleister Crowley might have resurfaced the idea of Daath as an 11th hidden sphere between Kether and Tiphareth in his book "Liber 777", syncretizing the concept with Kircher's symbols and von Rosenroth's diagrams. With the discovery of new planets, people might have tried to introduce more astrological symbols to their own versions of the diagram. As a result, there is no general agreement about the position of Uranus, Neptune and Pluto. However, in particular, it has been noted that Pluto bears resemblance with Daath: Pluto is a former planet, the last traditional celestial body to be discovered, and Daath is a hidden sphere, the last to be introduced. In the 21st century, enthusiasts might have rushed to attribute these collaborative works spanning centuries and involving several people through complex interactions to single authors. Thus, sometimes, the version where Malkuth has 3 paths is termed the "Tree of Emanation", and the version where Malkuth has 1 path is termed the "Tree of Return".
