The bottom half of the Visconti card features a rider on a horse. This man or woman wears a white tunic and red trousers. White and red are the colors that represent the polarities/duality in alchemy. The color white of the horse refers to the purification of animal nature.
Above the landscape with the horseman, castles, water and boats, a golden crown, symbol for ‘the crowning of creation’, stands out.
The card of the Charles VI, or Estensi, deck (right) contains an additional element that puts us on the trail of Sophia. The woman on the card has a black aureole, signifying that she represents one of the four cardinal virtues: Prudentia (Prudence, Wisdom), Justitia (Justice), Fortitudo (Strength), and Temperantia (Temperance).
The only one of the four virtues still missing from this tarot deck is Prudentia, wich is Latin for wisdom. The Greek word for wisdom is Sophia. In the Bible, Wisdom/Sophia is the name for the kundalini energy. For a substantiation of this statement, see my book.
In the past centuries when ‘heretical’ spirituality could not be communicated without repercussions, artists incorporated alchemical and other forbidden esoteric knowledge into their paintings. For those who have an eye for it, there are works of art in all museums and churches with references to the process of kundalini awakening. Below are two illustrations of Prudentia that incorporate kundalini symbolism. The serpent is a standard attribute of Prudentia.
