"One of the most significant changes between the original and the second version of the Art was in the visuals used. The early version used 16 figures presented as complex, complementary trees, while the system of the Ars Magna featured only four, including one which combined the other three. This figure, a "Lullian Circle," took the form of a paper machine operated by rotating concentrically arranged circles to combine his symbolic alphabet, which was repeated on each level. These combinations were said to show all possible truth about the subject of inquiry."
