Moonstranger, I think the major arcana symbols are a mixed bag really. Some of the symbols more ancient than others. Whether or not they represent an intelligible and consistent system of scientific laws, philosophy, or hidden truths is a subject of great debate. I personally believe that, like with many things, the tarot symbolism has many threads woven together by many people over time. Occultists and others have claimed to have discovered all kinds of systems hidden within the symbols but no one has demonstrated or proven that their theories are factual anywhere other than in their own imaginations.
